Those skilled in the art, in light of the teachings of this disclosure, will understand that alternative embodiments of the subject matter claimed herein are possible and will understand how to combine sequences taken from known vectors in order to construct such alternative embodiments. By way of example, existing vectors from the foregoing list may be modified by inserting additional origins of replication, or additional expression cassettes (non-limiting examples of expression cassettes are presented as SEQ ID NOs 48 and 49) comprising suitable promoter and termination sequences, or additional DNA binding sequences, or coding sequences for the hybrid protein (NHP) described herein. Those skilled in the art will understand and adopt the various alternatives known in the art, and will do so using techniques well known in the art. In particular embodiments, suitable origins of replication for use in embodiments include an origin of replication comprised within pDOJHR as well as the pB44 and pUC (E. coli) origins of replication. These are presented herein as SEQ ID NOs 28, 30, 29 respectively. In some embodiments adjacent functional components of a vector are joined by linking sequences.

In embodiments the vector comprises a eukaryotic expression cassette (a non-limiting example comprising GFP coding sequences is presented as SEQ ID NO: 49) containing a marker sequence to confirm both transformation and gene expression in the target eukaryotic cell. It will be understood that in alternative embodiments a range of alternative marker proteins and sequences are possible and for example in selected embodiments and without limitation the marker sequence encodes GFP (green fluorescent protein), RFP (red fluorescent protein), CAT (chloramphenicol acetyltransferase), luciferase, GAL (beta-galactosidase), or GUS (beta- glucuronidase). Those skilled in the art will readily understand and use all such marker sequences and reporter genes using standard techniques and materials readily available in the art.

Vectors according to embodiments comprise one or more prokaryotic expression cassettes. A non-limiting example of a prokaryotic expression cassette suitable for the expression of sequences in gram positive bacteria, and in embodiments in staphylococcus and bifidobacteria is presented as SEQ ID NO: 48. In embodiments such a cassette comprises a hybrid protein and embodiments of such hybrid proteins are disclosed herein.

TABLE 1: Sequences of exemplary CPP (transduction) domains

In this disclosure the term "DNA binding domain" means a protein sequence able to reversibly but tightly or with high affinity bind specifically to a suitable DNA sequence. In embodiments a DNA binding sequence may be a Zinc finger binding domain, and while a wide range of suitable domains and their complementary DNA binding sequences will be readily identified by those skilled in the art, a number of illustrative examples are disclosed in US Patent No. 6007988, issued on December 28, 1999. In particular embodiments hereof, the DNA binding motif or domain is or is derived from, Mer R, Zinc finger, or Histone like DNA binding protein or is or is derived from the HU protein or is or is derived from a homeobox DNA binding protein. It will be understood that the HU protein is generally considered a homeobox-like protein. While many types of DNA binding domains will be readily identified by those skilled in the art using available databases, screening methodologies and well known techniques, non-limiting examples of suitable DNA binding domains for use in alternative embodiments can be derived from a wide range of DNA binding proteins. In embodiments suitable DNA binding domains may be of any general type, including but not limited to helix-turn-helix, Zinc finger, leucine zipper, winged helix, winged helix turn helix, helix loop helix, HMG box, Wor 3 and RNA guided binding domains. Illustrative examples of DNA binding proteins whose DNA binding domains may be utilized in embodiments include histones, histone like proteins, transcription promoters, transcription repressors, transcriptional regulators, which may be drawn from a wide range of alternate sources and operons. In this disclosure the terms "polypeptide", "peptide", "oligopeptide" and "protein" are used interchangeably herein to refer to a polymer of amino acid residues. The terms apply to amino acid polymers in which one or more amino acid residues is an artificial chemical analogue of a corresponding naturally occurring amino acid, or is a completely artificial amino acid with no obvious natural analogue as well as to naturally occurring amino acid polymers. In embodiments the eukaryotic expression cassettes comprised in the vectors comprise suitable Kozak sequences, and the possible variations thereon and positioning thereof will be readily understood by those skilled in the art. One non limiting example is presented as SEQ ID NO: 49.

A peptide or peptide fragment is "derived from" a parent peptide or polypeptide if it has an amino acid sequence that is homologous to the amino acid sequence of, or is a conserved fragment from, the parent peptide or polypeptide. It will be understood that such sequences will, in alternative embodiments, comprise natural amino acids or will comprise artificially created amino acids. All of the foregoing will be readily identified by those skilled in the art.

In embodiments vectors have sequences which differ from the disclosed examples. It will be understood by those skilled in the art that a range of sequence variations are possible that do not affect or do not prevent the suitability of the vector for the purposes disclosed herein. By way of example and not limitation those skilled in the art will recognise that certain DNA sequences can be varied without materially affecting the function of the vector and others cannot. Again by way of illustration and not limitation, those skilled in the art will recognise and adopt sequence modifications known to enhance the function of a selected sequence, and will reject sequence modifications known to diminish such function. With particular reference to protein coding sequences those skilled in the art will recognise variable and conserved regions and will recognise mutations likely to change the structure and/or function of the relevant protein or polypeptide and those unlikely to do so. In general it will be understood that in particular variant embodiments the nucleic acid sequence of a vector will be 100% identical to one of the examples disclosed, or will be at least about, or about, or less than about 99%, 98%, 97%, 96%, 95%, 94%, 93%, 92%, 91 %, 90%, 89%, 88%, 87%, 86%, 95%, 84%, 83%, 82%, 81%, or 80% identical to one of the examples disclosed and that in embodiments such sequence identity will extend over all or only part of the length of the vector. It will be understood that in embodiments vectors will comprise alternative origins of replication, promoters, polyadenylation sites and the like. In embodiments vectors will comprise sequences inserted in the expression cassettes, and in embodiments vectors will have no insertions in the expression cassettes.

In embodiments the hybrid protein or polypeptide sequence encoded by a sequence comprised in an expression cassette according to an embodiment is 100% identical to one of the examples disclosed, or is at least about, or about, or less than about 99%, 98%, 97%, 96%, 95%, 94%, 93%, 92%, 91%, 90%, 89%, 88%, 87%, 86%, 95%, 84%, 83%, 82%, 81%, or 80% identical to one of the examples disclosed as SEQ ID NOs 24, 25, 26, 27 and such sequence identity extends over all or only part of the length of the protein or polypeptide.

In embodiments homologies and sequence identities extend over all or only a part of the sequence or sequences of interest. In embodiments homologies and sequence identities are limited to particular functional or sequence domains. In embodiments, homologies and sequence identities continuous and in embodiments are separated by regions of lower sequence identity or homology. Construction of vectors: In embodiments vectors and sequences set out herein are synthesized de novo using known techniques and commercially available DNA synthesis services. Standard techniques for the construction of the vectors of the present invention are well-known to those of ordinary skill in the art and can be found in such references as Sambrook et al., Molecular Cloning: A Laboratory Manual, 2nd ed., Cold Spring Harbor Laboratory Press, New York, (1989). A variety of strategies are available for ligating fragments of DNA, the choice of which depends on the nature of the termini of the DNA fragments and which choices can be readily made by the skilled artisan. In embodiments the sequences of vectors are determined using suitable DNA, RNA and protein sequence manipulation software, and the desired sequence is synthesized using suitable synthesis methods, a wide variety of which are readily available and will be immediately understood and implemented by those skilled in the art.

As described herein, an aspect of the present disclosure concerns isolated nucleic acids and methods of use of isolated nucleic acids. Plasmid Preparations: Plasmid preparations and replication means are well known in the art. See for example, U.S. Pat. Nos. 4,273,875 and 4,567,146 incorporated herein in their entirety. Some embodiments of the present invention include providing a portion of genetic material of a target microorganism and inserting the portion of genetic material of a target microorganism into a plasmid for use as an internal control plasmid.

Nucleic acids used as a template for amplification are isolated from cells according to standard methodologies. (Sambrook et al., 1989) The nucleic acid may be genomic DNA or fractionated or whole cell RNA. Where RNA is used, it may be desired to convert the RNA to a complementary cDNA. Pairs of primers that selectively hybridize to nucleic acids corresponding to specific sequences are contacted with the isolated nucleic acid under conditions that permit selective hybridization. Once hybridized, the nucleic acid primer complex is contacted with one or more enzymes that facilitate template-dependent nucleic acid synthesis. Multiple rounds of amplification, also referred to as "cycles," are conducted until a sufficient amount of amplification product is produced.

Next, the amplification product is detected. In certain applications, the detection may be performed by visual means. Alternatively, the detection may involve indirect identification of the product via chemiluminescence, radioactive scintilography of incorporated radiolabel or fluorescent label or even via a system using electrical or thermal impulse signals (Affymax technology; Bellus, 1994). Primers: The term primer, as defined herein, is meant to encompass any nucleic acid that is capable of priming the synthesis of a nascent nucleic acid in a template-dependent process. Typically, primers are oligonucleotides from ten to twenty base pairs in length, but longer- sequences may be employed. Primers may be provided in double-stranded or single-stranded form, although the single-stranded form is preferred. Specific primers used to amplify portions of vectors and nucleotide sequences according to embodiments are presented as SEQ ID NOs 35-40. Those skilled in the art will readily select alternative suitable primers for particular requirements.

Template Dependent Amplification Methods: A number of template dependent processes are available to amplify the sequences present in a given template sample. One of the best known amplification methods is the polymerase chain reaction (referred to as PCR) which is described in detail in U.S. Pat. Nos. 4,683,195, 4,683,202 and 4,800,159, and in Innis et al., 1990, each of which is incorporated herein by reference in its entirety.

A reverse transcriptase PCR amplification procedure may be performed in order to quantify the amount of mRNA amplified. Methods of reverse transcribing RNA into cDNA are well known and described in Sambrook et al., 1989. Alternative methods for reverse transcription utilize thermostable DNA polymerases. These methods are described in WO 90/07641 filed Dec. 21 , 1990. Polymerase chain reaction methodologies are well known in the art. Other amplification methods are known in the art besides PCR such as LCR (ligase chain reaction), disclosed in European Application o. 320 308, incorporated herein by reference in its entirety.

In another embodiment, Qbeta Replicase, may also be used as still another amplification method in the present invention. In this method, a replicative sequence of RNA which has a region complementary to that of a target is added to a sample in the presence of an RNA polymerase. The polymerase will copy the replicative sequence which may then be detected. Nucleic Acid Synthesis: Those skilled in the art will readily recognize a range of methods and apparatuses for synthesizing desired nucleic acid sequences. By way of example and not of limitation in a series of embodiments plasmids were synthesized in silico by GeneArt®, Life Technologies™

While the scope of the of methods for making embodiments includes any suitable methods (for example, Polymerase Chain Reaction, i.e., PCR, and nucleic acid sequence based amplification, i.e., NASBA) for amplifying at least a portion of the microorganism's genetic material, for one example, the present invention describes embodiments in reference to PCR technique.

Amplification of a genetic material, e.g., DNA, is well known in the art. See, for example, U.S. Pat. Nos. 4,683,202, and 4,994,370, which are incorporated herein by reference in their entirety. By knowing the nucleotide sequences of desired genetic material or target nucleic acid sequence, specific primer sequences can be designed In one embodiment of the present invention, the primer is about, but not limited to 5 to 50 oligonucleotides long, or about 10 to 40 oligonucleotides long or more about 10 to 30 oligonucleotides long. Suitable primer sequences can be readily synthesized by one skilled in the art or are readily available from third party providers such as BRL (New England Biolabs™), etc. Other reagents, such as DNA polymerases and nucleotides, that are necessary for a nucleic acid sequence amplification such as PCR are also commercially available.

Separation Methods: Following amplification, it may be desirable to separate the amplification product from the template and the excess primer for the purpose of determining whether specific amplification has occurred. In one embodiment, amplification products are separated by agarose, agarose-acrylamide or polyacrylamide gel electrophoresis using standard methods. See Sambrook et al., 1989.

Alternatively, chromatographic techniques may be employed to effect separation. There are many kinds of chromatography which may be used in the present invention: adsorption, partition, ion-exchange and molecular sieve, and many specialized techniques for using them including column, paper, thin-layer and gas chromatography (Freifelder, 1982).

Identification Methods: Amplification products must be visualized in order to confirm amplification of the desired sequences. One typical visualization method involves staining of a gel with ethidium bromide and visualization under UV light. Alternatively, if the amplification products are integrally labeled with radio- or fluorometrically-labeled nucleotides, the amplification products may then be exposed to x-ray film or visualized under the appropriate stimulating spectra, following separation.

In one embodiment, visualization is achieved indirectly. Following separation of amplification products, a labeled, nucleic acid probe is brought into contact with the amplified marker sequence. The probe preferably is conjugated to a chromophore but may be radiolabeled. In another embodiment, the probe is conjugated to a binding partner, such as an antibody or biotin, where the other member of the binding pair carries a detectable moiety.

In one embodiment, detection is by Southern blotting and hybridization with a labeled probe. The techniques involved in Southern blotting are well known to those of skill in the art and may be found in many standard books on molecular protocols. See Sambrook et al., 1989. Briefly, amplification products are separated by gel electrophoresis. The gel is then contacted with a membrane, such as nitrocellulose, permitting transfer of the nucleic acid and non-covalent binding. Subsequently, the membrane is incubated with a chromophore-conjugated probe that is capable of hybridizing with a target amplification product. Detection is by exposure of the membrane to x-ray film or ion-emitting detection devices.

In general, prokaryotes used for cloning DNA sequences in constructing the vectors useful in the invention include for example, any gram negative bacteria such as E. coli, E. coli strain K12 and bifidobacteria and staphylococcus Other microbial strains which may be used include P. aeruginosa strain PA01 , and E. coli B strain and bifidobacteria. These examples are illustrative rather than limiting. In particular embodiments steps in the construction of vectors may include cloning and propagation in suitable E. coli strains or in suitable bifidobacterium strains.

In general, plasmid vectors containing promoters and control sequences which are derived from species compatible with the host cell are used with these hosts. The vector ordinarily carries a replication site as well as one or more marker sequences which are capable of providing phenotypic selection in transformed cells. For example, a PBBR1 replicon region which is useful in many Gram negative bacterial strains or any other replicon region that is of use in a broad range of Gram negative host bacteria can be used in the present invention.

The term "recombinant polypeptide", "recombinant protein: or "fusion protein" or "hybrid protein" or like terms is used herein to refer to polypeptides that have been artificially designed and which comprise at least two polypeptide sequences that are not found as contiguous polypeptide sequences in their initial natural environment, or to refer to polypeptides which have been expressed from a recombinant polynucleotide. In particular embodiments, fusion proteins contain joining sequences to join protein domains that are not normally associated. In broad concept, in embodiments, fusion proteins comprise at least one sequence selected from the group consisting of: a DNA binding domain, a secretion signal sequence, and a trans-activator of transcription that is functional in Eukaryotic cells. In further embodiments fusion proteins comprise a CPP domain and in embodiments the CPP domain comprises a TAT domain. The hybrid proteins comprising signal sequence, transduction domain and DNA binding domain, are also referred to herein as simply "hybrid proteins" or as "NHPs" depending on the context. It will be understood that the different domains comprised in hybrid proteins according to embodiments may be present in any arrangement and any combination and any numbers of copies consistent with their function. Thus in embodiments signal sequences may be internal or may be terminal signal sequences and there may be multiple copies of one or more of each of the domains. In embodiments vectors may comprise one, two, three, four or more DNA sequences suitable for binding by the one or more DNA binding domains comprised in a hybrid protein according to embodiments. In embodiments vectors comprise a prokaryotic expression cassette for expressing an NHP in the gram positive bacterium and a eukaryotic expression cassette for expressing a candidate gene or sequence in a eukaryotic cell. .It will be understood that in alternative embodiments the prokaryotic expression cassette will contain other proteins desired to be expressed in the target gram positive bacterium, instead of one of the hybrid proteins disclosed herein. Thus in embodiments, vectors may be used to express a sequence or gene of interest in a prokaryotic cell.

In this disclosure the terms SHT, SZT, SLT, SMT are acronyms indicating currently preferred forms of the NHP. In the foregoing acronym descriptors Z indicates the presence of at least one Zinc finger DNA binding domain an example of the DNA sequence coding for which is presented as SEQ ID NO: 6 and the amino acid sequence as SEQ ID NO: 46 , H means the presence of at least one HU DNA binding domain an example of the DNA sequence coding for which is presented as SEQ ID NO: 44 and the amino acid sequence at SEQ ID NO: 44, T means a CPP or protein transduction domain examples of which are presented as SEQ ID NOs 11 through 17.

L represents a Lac-I DNA binding domain which is presented herein as SEQ ID NO: 47, it being understood that the inventors have found that hybrid proteins comprising the Lac-I DNA binding domain are not effective for the purposes hereof and are not embodiments of the subject matter claimed herein.

In embodiments presented the signal sequence is an alpha-L-arabinosidase signal sequence SEQ ID NOs 22, 23 but in alternative embodiments is the alpha amylase signal sequence SEQ ID NOs 18, 19 or a truncated version thereof SEQ. ID NOS. 20, 21 , are non-limiting alternatives. In embodiments the transduction domain T is Tat SEQ ID NO: 11 , but a number of non-limiting possible alternatives are presented herein. Sequences of exemplary SHT, SMT, SZT hybrid proteins are presented as SEQ ID NOs 24, 26 and 27. It will be understood that variant signal domains, CPP domains and DNA binding domains may be comprised in the hybrid proteins. Thus by way of example and not limitation, the S or signal sequence domain may be any suitable signal sequence, non-limiting examples being the alpha arabinosidase signal sequence, the alpha amylase signal sequence, and truncated versions of these and other signal sequences. The foregoing sequences, or their corresponding DNA sequence, are presented as SEQ ID NOs 18 through 23.

Possible CPP domains (identified as "T" in the abbreviations for the hybrid proteins according to embodiments) include Tat, Antp. Rev, VP22, PbetaMPG (gp41-SV40), Transportan (galanan mastoparan) and Pep1 (TRP rich motif SV40), or the biologically effective portions thereof. Amino acid sequences of the foregoing are presented as SEQ ID NOs 11-17. It will be understood that in embodiments the foregoing hybrid protein constructions will be comprised in the prokaryotic gene expression cassette of the vector and the foregoing prokaryotic expression cassette will be designed to be functional in a desired bacterial strain. In particular embodiments such strain is a gram positive bacterium and in embodiments is bifidobacterium. In embodiments it will be staphylococcus. It will likewise be understood that in embodiments the desired DNA for transformation into a target cell comprises a mammalian gene expression cassette for expression of a candidate sequence in the target cell. In embodiments the mammalian cell is a human cell.

The term "expression cassette" is used herein to describe a DNA sequence context comprising one or more locations into which a selected sequence may be inserted so as to be expressible as RNA. In general an expression cassette will comprise a promoter, transcription start site, transcription termination site. A sequence inserted at an appropriate location, between the transcription start and termination sites, will then be expressed when the cassette is introduced into a suitable host cell. In embodiments the choices of flanking sequences will be chosen to function in a chosen cell. Those skilled in the art will thus insert suitable sequences to be expressed in appropriate expression cassettes so that sequences desired to be expressed in a prokaryotic cell will be in a suitable sequence context and those desired to be expressed in eukaryotic cells will likewise be in a suitable sequence context. Those skilled in the art will readily adjust the sequences, structure and other aspects of the cassette to suit particular purposes or to function in particular bacterial strains. In one series of embodiments the coding sequences for a hybrid protein according to embodiments is bounded by a HU promoter and transcription initiation site and a HU transcription termination site. In another embodiment (pFRG1.5, FIG. 1 , SEQ ID NO: 2) the promoter is a ribosomal RNA promoter found in bifidobacteria, and the terminator is a ribosomal RNA terminator found in bifidobacteria. In embodiments the eukaryotic expression cassette comprises a suitable Kozak sequence.

In this disclosure the term "secretion signal", "secretion sequence", "secretion signal sequence", "signal sequence" and the like, refer to a protein motif that is effective to cause secretion of the protein across a cell membrane. In embodiments a secretion sequence is, or is derived from the alpha-L-arabinosidase signal sequence or is an alpha-amylase signal sequence or is a truncated alpha amylase signal sequence. Protein sequences for the foregoing are presented as SEQ ID NOs 23, 19 and 21 respectively and the encoding DNA sequences are presented as SEQ ID NOs 22, 18 and 20 respectively. Those skilled in the art will readily identify and implement suitable signal sequences which are useable in alternative embodiments. One listing of possible signal sequences is to be found in the signal sequence database at <www.signalpeptide.de> and in other resources such as SPdb - Signal Peptide Resource at <http://proline.bic.nus.edu.sg>.

While thousands of suitable signal sequences will be identified by those skilled in the art, using available databases, screening methodologies and well known techniques, non-limiting examples of sources for suitable signal sequences for use in alternative embodiments can optionally be derived from a range of secreted enzymes and other proteins, examples including carbohydrases such as amylases, sucrases, galactosidases, monoshaccharide transferases, lipases, phospholipases, reductases, oxidases, peptidases, transferases, methylases, ethylases, cellulases, ligninases, secreted signalling proteins, toxins and all manner of other secreted proteins.

Construction of suitable vectors containing the desired coding and control sequences can be achieved employing standard ligation techniques. Isolated plasmids or DNA fragments are cleaved, tailored, and religated in the form desired to form the plasmids required. In embodiments the vectors are synthesized de novo using suitable nucleic acid synthesis procedures as explained elsewhere herein. A range of alternative promoters, polyadenylation signals, DNA binding domains, cell penetrating peptide domains, signal sequences and the like will be readily identified by those skilled in the art using conventional methods and resources.

For analysis to confirm correct sequences in plasmids constructed, the ligation mixtures may be used to transform a bacteria strain such as £ coli K12 and successful transformants selected by antibiotic resistance using suitable selection markers and in embodiments the selection markers are antibiotics such as tetracycline, ampicillin spectinomycin, penicillin, kanamycin, gentamycin, zeomycin, methicillin, hygromycin B and others, all of which will be immediately recognized and used by those skilled in the art. Plasmids from the transformants are prepared, analyzed by restriction and/or sequenced. In alternative embodiments bacteria may be selected using suitable auxotrophic selection markers, non-limiting examples of which include the LEU2 and URA3 selection markers whose nature and use are well understood by those skilled in the art. In particular embodiments the selection marker confers resistance antibiotics effective against both gram positive and gram negative bacteria and in embodiments this is spectinomycin, tetracycline or chloramphenicol or erythromycin. In alternative embodiments the vector comprises multiple selection markers to permit selection using different antibiotics in gram positive and gram negative bacteria.

Host cells can be transformed with nucleic acid vectors of this invention and cultured in conventional nutrient media modified as is appropriate for inducing promoters, selecting transformants or amplifying genes. The culture conditions, such as temperature, pH and the like, will be apparent to the ordinarily skilled artisan.

"Transformation" refers to the taking up of vector or of a desired DNA sequence by a host cell whether or not any coding sequences are in fact expressed. Numerous methods are known to the ordinarily skilled artisan, for example, Ca salts and electroporation. Successful transformation is generally recognized when any indication of the operation of the vector or stable propagation of the introduced DNA occurs within the host cell.

It will be understood that the vectors and hybrid proteins disclosed herein are of particular value where standard or commonly used transformation procedures are not reliable.

As used interchangeably herein, the terms "nucleic acid molecule(s)", "oligonucleotide(s)", and "polynucleotide(s)" and "nucleic acids" and the like include RNA or DNA (either single or double stranded, coding, complementary or antisense), or RNA/DNA hybrid sequences of more than one nucleotide in either single chain or duplex form (although each of the above species may be particularly specified), as is consistent or necessary in context. The term "nucleotide" is used herein as an adjective to describe molecules comprising RNA, DNA, or RNA/DNA hybrid sequences of any length in single-stranded or duplex form. More precisely, the expression "nucleotide sequence" encompasses the nucleic material itself and is thus not restricted to the sequence information (i.e. the succession of letters chosen among the four base letters) that biochemically characterizes a specific DNA or RNA molecule. The term "nucleotide" is also used herein as a noun to refer to individual nucleotides or varieties of nucleotides, meaning a molecule, or individual unit in a larger nucleic acid molecule, comprising a purine or pyrimidine, a ribose or deoxyribose sugar moiety, and a phosphate group, or phosphodiester linkage in the case of nucleotides within an oligonucleotide or polynucleotide.

The term "upstream" is used herein to refer to a location which is toward the 5' end of the polynucleotide from a specific reference point.

The terms "base paired" and "Watson & Crick base paired" are used interchangeably herein to refer to nucleotides which can be hydrogen bonded to one another by virtue of their sequence identities in a manner like that found in double-helical DNA with thymine or uracil residues linked to adenine residues by two hydrogen bonds and cytosine and guanine residues linked by three hydrogen bonds (See Stryer, 1995, which disclosure is hereby incorporated by reference in its entirety).

The terms "complementary" or "complement thereof are used herein to refer to the sequences of polynucleotides which is capable of forming Watson & Crick base pairing with another specified polynucleotide throughout the entirety of the complementary region. For the purpose of the present invention, a first polynucleotide is deemed to be complementary to a second polynucleotide when each base in the first polynucleotide is paired with its complementary base. Complementary bases are, generally, A and T (or A and U), or C and G. "Complement" is used herein as a synonym from "complementary polynucleotide", "complementary nucleic acid" and "complementary nucleotide sequence". These terms are applied to pairs of polynucleotides based solely upon their sequences and not any particular set of conditions under which the two polynucleotides would actually bind. Unless otherwise stated, all complementary polynucleotides are fully complementary on the whole length of the considered polynucleotide. Digestion of DNA refers to catalytic cleavage of the DNA with a restriction enzyme that acts only at certain sequences in the DNA. The various restriction enzymes used herein are commercially available and their reaction conditions, cofactors and other requirements were used as would be known to the ordinarily skilled artisan. For analytical purposes, typically 1 pg of plasmid or DNA fragment is used with about 2 units of enzyme in about 20 pi of buffer solution. For the purpose of isolating DNA fragments for plasmid construction, typically 5 to 50 pg of DNA are digested with 20 to 250 units of enzyme in a larger volume. Appropriate buffers and substrate amounts for particular restriction enzymes are specified by the manufacturer. Incubation times of about 1 hour at 37°C are ordinarily used, but may vary in accordance with the supplier's instructions. After digestion the reaction is electrophoresed directly on a polyacrylamide gel to isolate the desired fragment.

Recovery or isolation of a given fragment of DNA from a restriction digest means separation of the digest on polyacrylamide or agarose gel by electrophoresis, identification of the fragment of interest by comparison of its mobility versus that of marker DNA fragments of known molecular weight, removal of the gel section containing the desired fragment, and separation of the gel from DNA. This procedure is known generally (Lawn, R. et al., Nucleic Acids Res. 9: 6103 6114 [1981], and Goeddel, D. et al., Nucleic Acids Res. 8: 4057 [1980]). Dephosphorylation refers to the removal of the terminal 5' phosphates by treatment with bacterial alkaline phosphatase (BAP). This procedure prevents the two restriction cleaved ends of a DNA fragment from "circularizing" or forming a closed loop that would impede insertion of another DNA fragment at the restriction site. Procedures and reagents for dephosphorylation are conventional (Maniatis, T. et al., Molecular Cloning, 133 134 Cold Spring Harbor, [1982]). Reactions using BAP are carried out in 50 mM Tris at 68°C. to suppress the activity of any exonucleases which may be present in the enzyme preparations. Reactions are run for 1 hour. Following the reaction the DNA fragment is gel purified.

Ligation refers to the process of forming phosphodiester bonds between two double stranded nucleic acid fragments (Maniatis, T. et al., Id. at 146). Unless otherwise provided, ligation may be accomplished using known buffers and conditions with 10 units of T4 DNA ligase ("ligase") per 0.5 pg of approximately equimolar amounts of the DNA fragments to be ligated.

Filling or blunting refers to the procedures by which the single stranded end in the cohesive terminus of a restriction enzyme-cleaved nucleic acid is converted to a double strand. This eliminates the cohesive terminus and forms a blunt end. This process is a versatile tool for converting a restriction cut end that may be cohesive with the ends created by only one or a few other restriction enzymes into a terminus compatible with any blunt-cutting restriction endonuclease or other filled cohesive terminus. In one embodiment, blunting is accomplished by incubating around 2 to 20 of the target DNA in 10 mM MgCI ₂ , 1 mM dithiothreitol, 50 mM NaCI, 10 mM Tris (pH 7.5) buffer at about 37°C. in the presence of 8 units of the Klenow fragment of DNA polymerase I and 250 μΜ of each of the four deoxynucleoside triphosphates. The incubation generally is terminated after 30 min. phenol and chloroform extraction and ethanol precipitation.

The terms "polypeptide" and "protein", used interchangeably herein, refer to a polymer of amino acids without regard to the length of the polymer; thus, peptides, oligopeptides, and proteins are included within the definition of polypeptide. This term also does not specify or exclude chemical or post-expression modifications of the polypeptides of the invention, although chemical or post- expression modifications of these polypeptides may be included excluded as specific embodiments. Therefore, for example, modifications to polypeptides that include the covalent attachment of glycosyl groups, acetyl groups, phosphate groups, lipid groups and the like are expressly encompassed by the term polypeptide. Further, polypeptides with these modifications may be specified as individual species to be included or excluded from the present invention. The natural or other chemical modifications, such as those listed in examples above can occur anywhere in a polypeptide, including the peptide backbone, the amino acid side-chains and the amino or carboxyl termini. It will be appreciated that the same type of modification may be present in the same or varying degrees at several sites in a given polypeptide. Also, a given polypeptide may contain many types of modifications. Polypeptides may be branched, for example, as a result of ubiquitination, and they may be cyclic, with or without branching. Modifications include acetylation, acylation, ADP-ribosylation, amidation, covalent attachment of flavin, covalent attachment of a heme moiety, covalent attachment of a nucleotide or nucleotide derivative, covalent attachment of a lipid or lipid derivative, covalent attachment of phosphotidylinositol, cross-linking, cyclization, disulfide bond formation, demethylation, formation of covalent cross-links, formation of cysteine, formation of pyroglutamate, formylation, gamma-carboxylation, glycosylation, GPI anchor formation, hydroxylation, iodination, methylation, myristoylation, oxidation, pegylation, proteolytic processing, phosphorylation, prenylation, racemization, selenoylation, sulfation, transfer-RNA mediated addition of amino acids to proteins such as arginylation, and ubiquitination. (See, for instance Creighton (1993); Seifter et al., (1990); Rattan et al., (1992)). Also included within the definition are polypeptides which contain one or more analogs of an amino acid (including, for example, non-naturally occurring amino acids, amino acids which only occur naturally in an unrelated biological system, modified amino acids from mammalian systems, etc.), polypeptides with substituted linkages, as well as other modifications known in the art, both naturally occurring and non-naturally occurring.

As used herein, the term "operably linked" refers to a linkage of polynucleotide elements in a functional relationship. A sequence which is "operably linked" to a regulatory sequence such as a promoter means that said regulatory element is in the correct location and orientation in relation to the nucleic acid to control RNA polymerase initiation and expression of the nucleic acid of interest. For instance, a promoter or enhancer is operably linked to a coding sequence if it affects the transcription of the coding sequence.

In this disclosure the term "shuttle vector" means a DNA vector which is able to replicate in both gram positive and gram negative bacteria and comprises a eukaryotic expression cassette suitable to express a sequence or gene of interest when introduced to a eukaryotic cell and a prokaryotic expression cassette able to express a gene of interest in a eukaryotic cell. In embodiments a first and second strains of host bacteria are from different genera, in embodiments they are from different species, and in embodiments they are from different subspecies. In embodiments the gram negative bacteria is an E. coli and in embodiments the gram positive bacteria is lactococcus, lactobacillus, bifidobacterium, or staphylococcus. It will be understood that a wide variety of combinations of first and second strains of host bacteria are possible in alternative embodiments and the foregoing exemplary combination of E. coli with other strains is in no way limiting. In embodiments shuttle vectors are plasmids. Thus the nucleic acid vectors disclosed herein are shuttle vectors able to replicate in both gram positive and gram negative bacteria of suitable types.

A "promoter" refers to a DNA sequence recognized by the synthetic machinery of the cell, or introduced synthetic machinery, required to initiate the specific transcription of a gene. The phrase "under transcriptional control" means that the promoter is in the correct location and orientation in relation to the nucleic acid to control RNA polymerase initiation and expression of the gene. The particular promoter employed to control the expression of a nucleic acid sequence of interest is not believed to be important, so long as it is capable of directing the expression of the nucleic acid in the targeted cell.

In embodiments the target eukaryotic cell is a mammalian cell. In embodiments the mammalian cell is a human cell and in embodiments is a cancer cell. In embodiments the cancer cell is a lung cancer cell, a colon (colorectal) cancer cell, a kidney cancer cell, or an ovarian cancer cell. In particular embodiments the cell is HEK-29 (human embryonic kidney); HT29, CaCo2 (both human adenocarcinoma); HeLa, LL2 (lung carcinoma). In embodiments the cells are cultured cells.

Where a cDNA insert is employed, typically one will typically include a polyadenylation signal to effect proper polyadenylation of the gene transcript. The nature of the polyadenylation signal is not believed to be crucial to the successful practice of the invention, and any such sequence may be employed. Also contemplated as an element of the expression construct is a terminator. These elements can serve to enhance message levels and to minimize read through from the construct into other sequences.

Kits: In some embodiments, there are disclosed kits comprising the vectors disclosed herein. In embodiments the kits comprise a quantity of vector DNA. Embodiments of exemplary nucleic acid vectors and their sequences are presented as FIG. 1 and 2 and SEQ ID NOs 1 and 2. In embodiments kits comprise a quantity of NHP. In embodiments the kits comprise instructions.

The container means of the kits will generally include at least one vial, test tube, flask, bottle, syringe or other container means, into which the vector, cells and/or primers may be placed, and preferably, suitably aliquoted. Where an additional component is provided, the kit will also generally contain additional containers into which this component may be placed. The kits of the present invention will also typically include a means for containing the probes, primers, and any other reagent containers in close confinement for commercial sale. In embodiments a kit will include injection or blow-molded plastic containers into which the desired vials are retained and in embodiments a kit will include instructions regarding the use of the materials comprised in the kit.

In this disclosure "gene of interest", "sequence of interest", "candidate gene" or "cargo gene" and like terms, refer to a sequence or gene that it is desired to transform into a target cell or that it is desired to express in a target cell. In embodiments hereof such sequences and genes are incorporated into vectors capable of expression of such sequence in particular target cells.

In this disclosure the term "target cell" means a cell into which it is desired to introduce a candidate or cargo gene or sequence. In embodiments a target cell is a eukaryotic cell and in embodiments is a mammalian cell. In embodiments a target cell is a prokaryotic cell.

In embodiments, vectors contain sequences necessary for efficient transcription and translation of specific genes or sequences encoding specific mRNA or siRNA sequences, in a target probiotic cell and may thus comprise transcription initiation and termination sites, enhancers and the like. Similarly any expressed RNA may comprise suitable translation start sites, ribosome binding sites, and the like. All of which will be readily identified by those skilled in the art.

More generally the term "expression cassette" is used herein to describe a DNA sequence context comprising one or more locations into which a selected sequence may be inserted so as to be expressible when present in a suitable cell type. In general an expression cassette will comprise a promoter, transcription start site, transcription termination site and other necessary or desirable sequences. In embodiments the expression cassette comprises a multiple cloning site suitable to permit the convenient insertion thereinto of a DNA sequence having compatible ends, and is able to be expressed as a translatable RNA by suitable cell types. In embodiments, rather than having a multiple cloning site, each expression cassette has restriction cut sites flaking 5' and 3' ends of promoter, gene of interest and terminator. It will be understood that in order for a protein to be expressed the insertion of the DNA sequence must be in the correct reading frame. A sequence inserted at an appropriate location, between the transcription start and termination sites, will then be expressed when the cassette is introduced into a suitable host cell and in embodiments such host cell is bifidobacteria! cell. It will be understood that where a chosen nucleotide sequence is said to be inserted into an expression cassette, or where it is said that an expression cassette comprises or includes a chosen nucleotide sequence, then such chosen nucleotide sequence will be inserted into such expression cassette in a form suitable for transcription and/or translation to generate a biologically active form of any protein or oligopeptide encoded thereby or will be expressible in the form of a suitable RNA species. Those skilled in the art will readily adjust the sequences, structure and other aspects of the cassette to suit particular purposes or to function in particular bacterial strains.

For clarity, this disclosure refers to both first and second expression cassettes non-limiting examples of which are presented as SEQ ID NOs 48, 49. In embodiments the first expression cassette is a prokaryotic expression cassette a non-limiting example being presented as SEQ ID NO: 48 and serves to express a desired fusion protein according to embodiments and the second expression cassette is a eukaryotic expression cassette and in embodiments serves to express a candidate DNA in a target cell. Thus in embodiments fusion proteins are encoded by a prokaryotic gene expression cassette and a cargo gene or sequence of interest is comprised in a eukaryotic or mammalian gene expression cassette.

In embodiments the construction of suitable vectors containing the desired coding and control sequences is achieved using standard ligation techniques. Isolated plasmids or DNA fragments are cleaved, tailored, and religated in the form desired to form the plasmids required. In alternative embodiments vectors, inserts, plasmids and any other nucleic acid sequences of interest, are synthesized de novo using standard nucleic acid synthesis techniques. In series of embodiments plasmids were synthesized in silico by GeneArt®, Life Technologies™, (Gene Art/Life Technologies™, Im Gewerbepark B35, Regensburg, 93059 Germany). Examples of other commercial nucleic acid synthesis providers are: DNA2.0 1 140 O'Brian Drive Suite A, Menlo Park CA, 94025 whose website is to be found at www.dna20.com; and Genewiz, 1 15 Corporate Boulevard, South Plainfield, NJ 07080 with a website at www.genewiz.com.

The different hybrid proteins display significant differences in binding affinities. Fig. 3 depicts the ability of SHT and SZT (SEQ ID NOs 24 and 27 respectively) to bind to a plasmid DNA (pBRA2.0 FIG. 1 and SEQ ID NO: 1). Fig. 3 shows that as concentrations of SHT (SEQ ID NO: 24) and SZT (SEQ ID NO: 27) increase, plasmid migration on a gel electrophoresis assay are retarded. The NHP library was used to characterize plasmid DNA transfection into various mammalian cell lines including HEK-293, Hela, CaCo-2, LL2 and HT-29s. Various plasmids encoding the Green Fluorescent Protein (GFP) gene under control of the Cytomegalovirus promoter were bound to NHPs from the library. The NHP-bound plasmids were then incubated with the various cell lines, and examined under fluorescent microscopy to detect GFP expression. As expected, DNA binding domains alone did not result in plasmid transfection; however HT, LT, MT, ZT, SHT (SEQ ID NO: 24) and SZT (SEQ ID NO: 27) did result in plasmid transfection with ZT, SHT and SZT having the best transfection efficiencies. Reverse orientation NHPs such as TL, TZ, TS, TM and THS result in very limited plasmid transfection. This suggests that the TAT domain and DNA binding domains are necessary for plasmid transfection, specifically in the orientation with TAT domain on the amino-terminal. In addition, these findings also suggest that the secretion signal domain S, improves the transfection efficiency. Fig. 10 depicts SHT and SZT mediated transfection of the pBRA2.0 SHT plasmid (SEQ ID NO: 1) in HEK-293 and Hela cell lines. All other cell lines tested demonstrated consistent results. A portion of the NHP library was used to examine the ability to transform bacteria with plasmid DNA. The NHP library included HT, ZT, TH, TZ, SHT and SZT. NHP-mediated transformation assays were tested on Bifidobacteria longum, Staphylococcus aureus and Escherichia coli. It was demonstrated that only SHT (SEQ ID NO: 24) and SZT (SEQ ID NO: 27) were able to transform Bifidobacteria longum, whereas HT, ZT, TH and TZ were unable to, suggesting that the secretion signal is necessary for this transformation ability. This experiment was then repeated with Staphyloccocus aureus and Escherichia coli confirming that SHT and SZT have cross-species transformation abilities. Compared to the traditional transformation method from gram-positive bacteria, electrotransformation, the use of SHT has been demonstrated to be superior, resulting in a higher rate of transformants. As SHT and SZT transform diverse bacterial species, it is believed that other bacterial species, both gram-positive and gram- negative will be able to effectively be transformed via this method. This includes species difficult to transform, similar to Bifidobacteria longum, which genera include, lactococcus, Clostridium, bacillus, and streptococcus.

NHP-mediated gene delivery to both bacterial as well as mammalian target cells may therefore function through a cell-mediated internalization process. It is believed that the process requires the TAT domain and is enhanced with secretion signal domain. For bacterial cell transformation, it is believed that a species specific section signal plays a significant role in transformation efficiencies, based on the reduced transformation efficiencies observed in Staphylococcus aureus and Escherichia coli assays compared to Bifidobacteria longum.

EXAMPLE 2

PLASMID PREPARATION A DNA plasmid was designed and created to use Bifidobacteria longum as a vector for NHP- mediated gene delivery to mammalian cells (Figs. 1 and 2). The vector is comprised of 6 components that encode information allowing the bifidobacteria to carry out its designed function. The genetic components encoded include: (a) A mammalian expression cassette; (b) A prokaryotic expression cassette, encoding a novel hybrid protein; (c) A origin of replication in E. coli; (d) An origin of replication in bifidobacteria longum; (e) A selectable marker; (f) Specific DNA binding sites for the novel hybrid protein. A more detailed explanation of the structure of the two vectors is presented above in the descriptions of embodiments.

Briefly, in the plasmid pBRA2.0 SHT (FIG. 1 and SEQ ID NO: 1 ) the first expression cassette for expression in a gram positive bacterium comprises an HU promoter and terminator flanking the NHP encoding sequences as will be seen in FIG. 1. In pBRA2.0 SHT the second expression cassette for expression in a human cell, comprises the CMV (cytomegalovirus) promoter, a KOZAK sequence and a Thymidine Kinase polyadenylation/termination sequence, the foregoing flanking an insertion sequence for the insertion of a cargo sequence. This will be seen in SEQ ID NO: 1 wherein a GFP protein is inserted into the second expression cassette. In the embodiment pBRA2.0 SHT the vector comprises a pUC origin of replication for replication in E. coli and a pB44 origin of replication for replication in Bifidobacterium. DNA-BS denotes a nucleotide binding site (SEQ. ID. NO. 43) for a Zinc finger DNA binding protein (SEQ ID NO: 46).

Plasmid pFRG1.5 SHT is shown in FIG. 2 and SEQ ID NO: 2 and the numbers refer to the numbering of features in FIG. 2. The vector comprises gram-positive origin of replication, namely the PDOJHR origin of replication (2) whose sequence is comprised within SEQ ID NO: 28 and a gram negative origin of replication, namely the pUC ORI (1) presented as SEQ ID NO: 29. The prokaryotic expression cassette comprises a Ribosomal RNA promoter (8) and terminator (10) flanking coding sequences (9) for the hybrid protein SHT, defined elsewhere herein. The mammalian gene expression cassette comprises a CMV promoter (4) and a TK Poly A site and terminator (6). In this case the inserted gene is a GFP reporter sequence (5). The plasmid comprises DNA sequences (1 1 ) suitable for binding by the sequence comprised in the SHT hybrid protein. The selectable marker in the pFRG1.5 plasmid is a spectinomycin resistance gene (3).

Once the vector is inserted into the bifidobacteria, components (b), (d) and (0 are designed to activate due to interactions with the bifidobacteria cell machinery. As a result, the novel hybrid protein is expressed, binding to a specific binding site on the vector, and results in the entire vector-novel hybrid protein complex being secreted out of the bifidobacteria and delivered into mammalian cells. Once in the mammalian cell, the mammalian expression cassette component activates due to interactions with the cell machinery and it expresses the therapeutic gene to carry out a desired function. Components (c) and (e) are not therapeutically relevant but are required during the construction and validation of the technology.

The function of each component was tested experimentally after having the vector synthesized from GeneArt Inc.

A mammalian gene expression cassette

The ability of the vector to express the mammalian gene expression cassette was examined in various mammalian cell culture lines including LL2, Hela, Hek-293, HT-29 and CaCo-2 cells. A mammalian expression cassette that contained the Green Fluorescent Protein gene was used, allowing the use of fluorescent microscopy to detect proper function of the genetic component. Fig. 5 depicts pBRA2.0 SHT (SEQ ID NO: 1) transfection in HeLa and HEK-293 cell lines, and resulting mammalian expression cassette function. A prokaryotic gene expression cassette

The ability of the vector to express the prokaryotic mammalian gene expression cassette in Bifidobacteria longum was examined. To do this, immunoblot analysis on cell lysate of Bifidobacteria longum was performed. Fig. 9 depicts the immunoblot, with a band being detected at the predicted NHP size of 14 kDa in lane 9. An origin of replication in E.coli and selectable marker

To test this component, E.coli cells were transformed with pBRA2.0 SHT (SEQ ID NO: 1 ). After propagating them, plasmid were purified followed by gel electrophoresis to confirm positive transformants and the function of the origin of replication. Fig. 4 depicts the gel electrophoresis of pBRA2.0 SHT (SEQ ID NO: 1 , FIG. 1 ) purified from E.coli and confirms positive transformants. After transformation the culture was propagated in spectinomycin containing culture broth. Propagation in this broth suggests the plasmid is being replicated and the selectable marker functions.

An origin of replication in bifidobacteria longum and selectable marker

To test this component, bifidobacteria cells were transformed with pBRA2.0 SHT (SEQ ID NO: 1 , FIG. 1 ) purified from E.coli. After transformation the culture were propagated in spectinomycin containing culture broth. Propagation in this broth suggests the plasmid is being replicated and the selectable marker functions.

A specific DNA binding site for NHPs

To test this function, purified pBRA2.0 SHT (SEQ ID NO: 1 , FIG. 1) was used and bound with SHT and SZT (SEQ ID NOs 24 and 27) proteins. Fig. 3 depicts this binding assay with pBRA2.0 SHT migration being retarded with increasing NHP concentrations. Additionally, SHT and SZT mediated pBRA2.0 SHT delivery to various cell lines were performed. The positive result is the expression of the mammalian gene expression cassette encoding GFP. Fig. 5 depicts GFP positive cells post NHP-mediated pBRA2.0 SHT (SEQ ID NO: 1 , FIG. 1) transfection.

Collective Vector function:

After validating the components of the vector independently their collective function as a gene delivery system were examined. To do so, NHP-bound pBRA2.0 SHT (SEQ ID NO: 1 , FIG.1) was screened for in the supernatant of Bifidobacteria longum cultures. The first step was to detect pBRA2.0 SHT (SEQ ID NO: 1 , FIG. 1 ) plasmid DNA via PCR (Fig. 6). After rigorous centrifugation, supernatants of wild-type bifidobacteria, pTM13 positive transformants and pBRA2.0 SHT positive transformants were collected. pTM13 is the same vector as pBRA2.0 SHT without the prokaryotic gene expression cassette encoding NHP, as a result we anticipated no plasmid secretion in pTM13 transformants. After the PCR, positive controls confirmed the validity of the PCR reaction, whereas negative control, including wild- type and pTM13 positive transformants did not have template amplification. Only pBRA2.0 SHT positive transformants provided amplified template from isolated supernatant.

Second, pBRA2.0 SHT (SEQ ID NO: 1 , FIG. 1) was isolated from the supernatant, using plasmid purification protocols on the collected supernatant that included modified Qiagen™ prep kits, as well as traditional phenol-chloroform purification protocols (Figs. 7 and 8). The figures depict an isolated vector corresponding to the size of pBRA2.0 SHT (SEQ ID NO: 1 , FIG. 1), and upon restriction digest analysis, was confirmed to be pBRA2.0 SHT.

It is believed that increasing the expression of NHP and the copy number of the vector will provide sufficient NHP-bound vector to detect NHP-mediated gene delivery in mammalian cells. To do this, a vector having enhanced versions of component (b) and component (d) such as pFRG1.5 (SEQ ID NO: 2, Fig. 2). It is also believed that changing the components to become species specific, for another species is relatively straight forward, as other gene expression cassettes, origins of replications, and selectable markers can be identified through genomic analysis. Based on the current designs, it is believed that the vector can be specifically designed and tested to work in species similar to Bifidobacteria such as lactococcus, Clostridium, staphylococcus, streptococcus and bacilius.

CULTURE TECHNIQUES, SERIAL PASSAGES, PLATING AND STORAGE OF

BIFIDOBACTERIA.. CELLS Bifidobacterium longum cells were subcultured in screw capped anaerobic tubes containing 7- 7.5 mL RCB (Reinforced Clostridial broth). After 18-24 hours of incubation, the cells were plated on RCBA (Reinforced Clostridial agar) and incubated for 24-48 hours at 37°C under anaerobic conditions. A single colony was picked and again subcultured in screw capped anaerobic tubes containing 7-7.5 mL RCB. This procedure of 2 serial subcultures or passages (10% V/V) was used as a starter culture for all the experiments. After the cells reach an OD ₆₀₀ nm of 1.4-1.8, cell pellets were collected and frozen at -80°C for future use. Also, a glycerol stock of 2 mL of active culture is added to 0.5-1 mL 50% of sterile glycerol in a cryo vial and stored at -80°C. To obtain an active bacterial cell culture, the cells were constantly passaged every 2 days in sterile RCB tubes. EXAMPLE 4

ELECTROTRANSFORMATION IN BIFIDOBACTERIUM LONGUM Preparation of cells for electroporation

Bifidobacterium longum overnight culture (10% V/V) was inoculated in fresh Reinforced Clostridial broth (RCB) in 10 mL screw capped anaerobic tubes and incubated at 37°C under anaerobic conditions. This culture was serially passaged in sterile RCB tube again under anaerobic conditions at 37°C until an OD ₆₀ o _nm of 0.6-0.7 was reached. Once the cells reached mid-exponential phase, the cells were first chilled on ice and centrifuged at 4,500 rpm for 15 min at 4°C in a 15 mL Falcon tube. After centrifugation, the cell pellet was resuspended and washed twice with ice-cold 0.5 M sucrose in eppendorf tubes. After, the cells were resuspended in 1/250 of the original culture volume (10 mL), which is 300 pL of ice-cold electroporation citrate buffer consisting of 1 mM ammonium citrate + 0.5 M sucrose (pH- 6.) at 4°C for 2.5 hours.

Electroporation protocol

Plasmid DNA (400, 600, 800, 1000 ng: 800 ng best) were mixed with 80 pL cell suspension in a precooled Bio-Rad™ Gene Pulser™ disposable cuvette with an interelectrode distance of 0.2 cm. A Bio-Rad™ Gene Pulser™ was used to deliver a high-voltage electric pulse of 2000 V along with 25 pF capacitance and 200 Ω resistance. Following electroporation, the transformant mixture was transferred in eppendorf tubes containing 900-920 μί of sterile RCB containing 0.5 M sucrose and the cells were incubated at 37°C for 3-4 h inside the anaerobic glove bag. This procedure is required for cell recovery and the expression of antibiotic resistance marker. After cell recovery, the cells were subcultured on sterile RCB containing 25, 50, and 100 pg/mL of Ampicillin and Spectinomycin antibiotics respectively and incubated at 37°C for 2-4 days.

Selection of transformants

For selection, RCBS and RCBAS (Reinforced Clostridial medium with spectinomycin for vector PTM13) were used for selection of transformants. The concentrations used for selection of positive transformants were 50 pg/mL, 75 pg/mL, 100 pg/mL, 125 pg/mL and 150 pg/mL spectinomycin in tubes and agar plates. For preparing liquid selective media, the above- mentioned concentrations of spectinomycin were added to sterile RCBS tubes inside the anaerobic glove bag asceptically. For selection of transformants after electroporation, 50-100 pL of transformant mixture was plated using spread plate technique on to sterile RCAS agar plates pre-spread with appropriate concentrations of spectinomycin and incubated for 48-72 h at 37°C inside the glove bag. Control plates containing the same concentrations of spectinomycin were used for both sterile tubes and agar plates containing (10% V/V for liquid broth and 50-100 pL of culture for agar plates) wildtype Bifidobacerium longum cells. After 48-72 hours or even further sometimes, the positive transformant colonies were picked using a sterile loop inside the glove bag and subcultured in tubes containing selective RCBS with 125 pg/mL spectinomycin. No growth was observed on the control RCBAS plates with the same concentrations of spectinomycin even after a week.

Screening positive transformants:

Plasmid Isolation Harvest the cells (6-7 ml. culture) at 5,000 rpm at 4°C for 15 min after overnight growth from single colonies from the selective agar plates in 15 mL Falcon tubes. Wash the pellets with 1 mL of PBS once to remove excess end products in the medium. Resuspend pellets with 570 μΙ_ of solution A {6.7% sucrose, 50 mM Tris-HCI, 1 mM EDTA (pH-8.0)} and prewarm at 37°C for 5 min. Cell lysis was performed by the addition of 145 μΙ_ of solution B {25 mM Tris-HCI (pH-8.0), 20 mg/mL Lysozyme} and incubated at 37°C for 40-45 min.

The supernatant was added to a new eppendorf tube containing 700 μΙ_ of phenol:chloroform:isoamyl alcohol mixture (25:24:1) and mixed vigorously. Following that, the mixture was centrifuged at 14,000 rpm for 15-20 min at room temperature. After centrifugation, the upper aqueous phase was transferred to a new tube by careful aspiration or gentle pipetting and treated with 600 μΙ_ of isopropanol and the DNA was precipitated for 30 min on ice. Then, the tubes were centrifuged at 14,000 rpm for 15- 20 min at 4°C. After centrifugation, the supernatant was discarded and the pellets were washed with ice-cold (-20°C) 70% ethanol. After centrifugation at 14,000 rpm for 10 min, the supernantant was discarded and the pellets were air-dried for 5-10 min.

Then, the reaction was heat inactivated at 65°C for 10-15 min. The samples including transformant (cut, uncut) plasmid DNA, control: wildtype grown in the absence of antibiotic (cut, uncut), control: wildtype grown in the presence of antibiotic (cut, uncut), vector DNA (PTM13) cut/uncut, and DNA ladders were loaded on 1.5% agarose gel and electrophoresed to see the appropriate band patterns.

Other Plasmid Isolation Protocols

Buffers needed: TES (25 m Tris-CI, 10 mM EDTA, 50 mM sucrose); KOAc: 3 M K ⁺ , 5 M acetate (3 M potassium-acetate, 2 M acetic acid - glacial is 17 M); PBS, phosphate buffered saline pH 7.0. 1ml_ of fresh culture grown anaerobically at 37°C with mid-log phase OD (~8-10 h) was used for plasmid isolation. Centrifuge 20 min at 4,000 RPM at 4°C in centrifuge. Discard the supernatant, and wash in 5 mL of PBS buffer (pH 7.0). Centrifuge again and discard supernatant. Add 300- 400 μί TES containing 6 mg/mL lysozyme and 40 Mg/mL mutanolysin and resuspend the pellet in a 2 mL eppendorf tube. Incubate at 37°C for 60 minutes. With O'Sullivan's method, used 200 μί of 25% sucrose with 30 mg/mL lysozyme as resuspension buffer and incubated for 15-20 min at 37°C. Meanwhile, 0.2 N NaOH and 2% SDS was freshly made to perform lysis. Add 600 μί SDS/NaOH mix to each tube. Incubate on ice for 5 min. With O'Sullivan's method, also tried with 400 [si of lysis buffer (3% SDS and 0.2 N NaOH) and mixed by inversion and incubating at room temperature for 5-7 min. Add 500 μί KOAc (3M K\ 5M acetate). Incubate on ice for 2 min. Shake vigorously and centrifuge at 17,200 g/12,000 rpm, 4°C, for 15 min.

Remove supernatant (~1 mL) into a fresh 2 mL tube and discard the pellet and remaining supernatant. Add ½ volume (500 μί) of isopropanol. Centrifuge at 17,200 g/12,000 rpm (room temperature) for 10 min. Discard the supernatant. With O'Sullivan's method, the supernatant was collected in a new eppendorf and mixed with room temperature 650 μί isopropanol and centrifuged at 13, 500 rpm for 10 min at 4°C. Wash pellet with 1mL 70% ethanol. Air dry for 2-5 min on bench. Resuspend in 500 μί TE buffer. Add 500 μί 5M LiCI. Incubate on ice for 5 min. Centrifuge at 17,200 g/12,000 rpm for 10 min.

In the example a pBRA2.0 SHT plasmid containing the GFP marker was transformed into bifidobacteria! cells. The bifidobacteria! cells were confirmed as hosting the plasmid, and expressing the encoded NHP protein. Secretion of the pBRA2.0 plasmid from the bifidobacteria! cells was confirmed directly. pBRA2.0 SHT E. coli transformation assay to validate the function of the E. coli ORI pBRA2.0 SHT was purified from transformed E coli DH5a chemically competent cells to validate the £ coli ORI on pBRA2.0 SHT. Positive transformants were selected for on agar plates containing 100 pg/pL of spectinomycin. Cells were subject to plasmid purification using Qiagen QIAprep Spin Miniprep Kit following manufacturers protocols and subject to restriction enzyme digest using EcoR1 and visualized on a 0.8% agarose gel.

Validation of secretion of vector. PCR screening of pTM13 and pRBA2.0 supernatants, validation of pBRA2.0 SHT secretion

Cultures were grown to OD 1.8 where 1 mL of supernatant for wild-type, pTM13 (a plasmid not containing the SHT sequence) and pBRA2.0 SHT cultures were subjected to plasmid purification using Qiagen™ QIAprep™ Spin Miniprep Kit following manufacturers protocols. Resulting eluates were subject to PCR using pTM13/pBRA2.0 SHT specific primers to validate plasmid secretion from pBRA2.0 SHT transformants.

EXAMPLE 8 WESTERN BLOT ANALYSIS OF SZT, SHT VALIDATION OF BIFIDOBACTERIUM SPECIFIC

ORF

Wild-type, and pTM13, pBRA2.0-SHT and pBRA2.0-SZT transformed cultures were grown to an OD of 1.8. Samples were loaded onto an 0.8% PACM gel and subject to electrophoresis, and transferred to a membrane for immunoblot analysis using anti-TAT antibodies to detect the expression of our hybrid proteins SHT and SZT SEQ ID NO: 27, to validate the functionality of the Bifidobacterium specific promoter and terminator. Samples were prepped from freshly grown cells washed three timex in sterile PBS. Cells were pelleted and subject to sonication in deionoized water with three pulses of 20 seconds with 30 second intervals in an ice bath. Samples were quantified using via Bradford and aliquots of each sample were mixed with 4x SDS loading dye and boiled at 95 degree Celsius for 10 minutes and quenched on ice. These results suggest the promoter and terminator functionality of the HU design on pBRA2.0 is sufficient for protein expression. Results are shown in FIG. 9. 1.
