Description
OverviewB834 is the parental strain for BL21 (1). These protease-deficient hosts are methionine auxotrophs and allow high specific-activity labeling of target proteins with 35S-methionine and selenomethionine for crystallography (2).

DE3 indicates that the host is a lysogen of λDE3, and therefore carries a chromosomal copy of the T7 RNA polymerase gene under control of the lacUV5 promoter. Such strains are suitable for production of protein from target genes cloned in pET vectors by induction with IPTG.
