These plasmids allow you to perform bacterial transformations, conferring new antibiotic resistance, as a visual way of demonstrating gene transfer.

• Purchase only the amount of plasmid you need
• Many plasmids already contain loading dye for added convenience

Plasmid pUC19: 2686 base pairs. Confers antibiotic resistance to ampicillin and complements defects in b-galactosidase in appropriate bacterial strains. Isolated from E. coli JM101.

pBR322: 4361 base pairs. Commonly used plasmid cloning vector for E. coli, and confers resistance to Ampicillin and Tetracycline.
