Description

BL21(DE3) is a chemically competent E. coli cell suitable for transformation and high level protein expression using a T7 RNA polymerase-IPTG induction system.

BL21 strains are the most widely used hosts for protein expression from pET recombinants and have the advantage of being deficient in both lon and ompT proteases.
