Descripción

Descripción general

Origami B host strains carry the same trxB/gor mutations as the original Origami strains, except that they are derived from a lacZY mutant of BL21. Thus the Origami B strains combine the desirable characteristics of BL21, Tuner and Origami hosts in one strain background. The trxB and gor mutations are selectable on kanamycin and tetracycline, respectively; therefore, this strain is recommended for use with pET plasmids carrying the ampicillin resistance marker bla.

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.

pLysS strains express T7 lysozyme, which further suppresses basal expression of T7 RNA polymerase prior to induction, thus stabilizing pET recombinants encoding target proteins that affect cell growth and viability.
