pBR322 Vector

Product Introduction

  • View sequence details
  • 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.
