pBR322 Description

The pBR322 plasmid has a small relative molecular weight and has a replication initiation site, which ensures that the plasmid can only replicate in E. coli cells. There are two antibiotic resistance genes, ampicillin resistance gene and tetracycline resistance gene, which can be used as selective markers for transformants. With high copy number, each cell can accumulate 1000-3000 copies after chloramphenicol amplification, which provides great convenience for the preparation of recombinant DNA. At the same time, because of its artificial construction of plasmids, although with resistance genes, but can not transfer between natural host cells, and the use of safe strains, will not cause antibiotic resistance gene transmission.

PBR322 is an important plasmid constructed artificially and has universal plasmid. It was constructed by a complex recombination process of pSF2124, pMB1 and pSC101 three parental plasmids.

The size of plasmid vector pBR322 is 4361bp, and its relative molecular weight is the first advantage. The second advantage is that it carries a replication initiation site, which ensures that the plasmid can only replicate in E. coli cells. It has two antibiotic resistance genes, ampicillin resistance gene and tetracycline resistance gene. Selective markers for transformants are its third advantage.
