Traditional Cloning Workflow
pBR322 DNA is a commonly used plasmid cloning vector in E. coli (1). The molecule is a double-stranded circle 4,361* base pairs in length (2). pBR322 contains the genes for resistance to ampicillin and tetracycline, and can be amplified with chloramphenicol. The molecular weight is 2.83 x 106 daltons.
*Sequencing data from Watson (confirmed at New England Biolabs, Inc.) has shown pBR322 to be 4,361 base pairs, not 4,363 base pairs as previously reported.
Product SourcepBR322 is isolated from E. coli ER2686 (dam +dcm + EcoK M-) by a standard plasmid purification procedure.
