BL21(DE3)

F– ompT gal dcm lon hsdSB(rB- mB-) λ(DE3)
- an E. coli B strain with DE3, a λ prophage carrying the T7 RNA polymerase gene and lacIq
- Transformed plasmids containing T7 promoter driven expression are repressed until IPTG
induction of T7 RNA polymerase from a lac promoter.

BL21 (DE3) pLysS

F- ompT gal dcm lon hsdSB(rB- mB-) λ(DE3) pLysS(cmR)
- pLys plasmid chloramphenicol resistant; grow with chloramphenicol to retain plasmid
- Chloramphenicol resistant
- The pLysS plasmid encodes T7 phage lysozyme, an inhibitor for T7 polymerase which
reduces and almost eliminates expression from transformed T7 promoter containing plasmids
when not induced.
