HMS174 strains provide the recA mutation in aK-12 background. Like BLR, these strains maystabilize certain target genes whose productsmay cause the loss of the DE3 prophage.

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.

HMS174 strains provide high transformation efficiencies and the recA mutation in a K-12 background. Strain may stabilize certain target genes whose products may cause the loss of the DE3 prophage.
