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 Gateway® pDEST™ vectors

Includes 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—One Shot® E. coli
