Reliable prokaryotic systems to fit every expression scale

Producing large quantities of protein quickly and economically often requires using a bacterial host organism. We offer a variety of systems for the expression of recombinant proteins in Escherichia coli (E. coli). 

Featured bacterial protein expression categories

Ideal for nontoxic, recombinant protein expression in E. coli—pRSET and Invitrogen Gateway pDEST vectors

Includes Invitrogen Champion pET, our strongest promoter, to help you achieve maximum protein production

Tightly controlled expression of toxic proteins and optimized protein solubility—pBAD

Comprehensive selection of reliable and efficient BL21 strains—Invitrogen One Shot E. coli

Bacterial culture products, growth media, and reagents
