BL21(DE3) E. coli are ideal for use with bacteriophage T7 promoter-based expression systems ( e.g. , pRSET, pCR¤T7, and pET). BL21(DE3) carry the lambda DE3 lysogen. Recombinant proteins that are non-toxic to E. coli are generally expressed at higher levels in BL21(DE3) cells than in BL21(DE3)pLysS or BL21(DE3)pLysE. However, the basal expression levels of heterologous genes are significantly higher in BL21(DE3) than in BL21(DE3)pLysS or BL21(DE3)pLysE.

BL21(DE3)pLysE E. coli are ideal for use with T7 promoter-based expression vectors. Like BL21(DE3)pLysS E. coli , BL21(DE3)pLysE carry the lambda DE3 lysogen. In addition, BL21(DE3)pLysE cells contain the pLysE plasmid, which constitutively expresses T7 lysozyme. T7 lysozyme reduces the basal expression of target genes by inhibiting T7 RNA polymerase. The pLysE plasmid in BL21(DE3)pLysE expresses higher levels of T7 lysozyme than the pLysS plasmid in BL21(DE3)pLysS. The BL21(DE3)pLysE strain provides tighter control of T7 RNA polymerase, which is necessary when the recombinant protein to be ex...
