| E. cloni EXPRESS BL21(DE3) Electrocompetent Cells are an E. coli strain that is ideal for routine
protein expression applications. NOTE: for expressing toxic proteins, we recommend Lucigen’s
OverExpress™ C41(DE3) and C43(DE3) Competent Cells.
BL21(DE3) is a lysogen of λDE3. This strain carries a chromosomal copy of the T7 RNA
Polymerase gene under the control of the lacUV5 promoter. This strain is suitable for production of
protein from target genes cloned into T7 driven expression vectors. E. cloni Express BL21(DE3) is
also deficient in the lon and ompT proteases. |
