Title:
IMPROVED PROMOTER AND CARRIER COMPOSED OF SAME AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/128837
Kind Code:
A1
Abstract:
An improved promoter and application thereof; the improvement refers to the mutation of a nucleotide sequence, in the promoter area, between -35 area to -10 area into an endonuclease recognition site. The improvement may overcome the problem existing in blue-white screening vectors that poisonousness may be produced to the host, which leads to clone incapability, when transcription or translation product of a foreign gene is promoted by a strong promoter. Thus, the defect of false positive clone resulted from gene frame shift mutation which is caused by the deficiency of the vector of 1-2bp at the restriction enzyme cutting site can be avoided, and the false negative phenomenon of a panel being full of locus coeruleus due to smaller foreign DNA fragments and the insertion of foreign DNA not changing the reading frame of the gene can be eliminated.
