Recombinant expression in BL21(DE3) E. coli is a relatively simple and cost-effective method for production of certain recombinant proteins. Many of these products are intended for use as therapeutic agents in humans and animals, and as such, must be highly purified. The manufacturing and purification process of these products leaves the potential for contamination by … Continue reading Introducing BL21(DE3) Host Cell Protein ELISA Kit
