Bacterial Protein Expression | Thermo Fisher Scientific

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).
