BL21 (DE3) pLysS receptive cells produced by our company are receptive cells obtained by special processing of Escherichia coli BL21 (DE3) pLysS strain, which can be used for chemical transformation of DNA. Using pUC19 plasmid detection, the conversion efficiency can reach 107, and the conversion efficiency does not change after 6 months of storage at -70℃.
Genotypes: F-, ompT, hsdSB(rB-mB-), dcm, gal(DE3), pLysS, Cmr
Characteristics: This strain carries the plasmid pLysS and is therefore resistant to chloramphenicol. Plasmid pLysS contains genes expressing T7 lysozyme, which can reduce the background expression level of target genes, but does not interfere with the expression of target proteins. The bacterium is suitable for expressing both toxic and non-toxic proteins.
