Title:
マルチコピー遺伝子タンパク質発現系
Document Type and Number:
Japanese Patent JP7278261
Kind Code:
B2
Abstract:
The present invention belongs to the field of biotechnology, specifically to the field of recombinant protein expression. The present invention focuses on two problems commonly encountered during recombinant protein expression, low quantity of protein expression and genetic instability of cell lines used for recombinant protein expression. The basic principle of the present invention is to introduce several expression cassettes into a cell which expression cassettes all code for the same mature recombinant protein of interest, but which expression cassettes have different nucleotide sequences. Expression cassette means a polynucleotide sequence which comprises at least a promoter sequence, a start codon, a polynucleotide sequence coding for a protein which is intended to be recombinant expressed (POI), a stop codon and a terminator.
