BL21 (DE3) Escherichia coli Strains Description
BL21 (DE3) is an E.coli Expression strain, which is a protein expression host with T7 RNA polymerase as the expression system. The expression of T7 phage RNA polymerase gene is controlled by lacuv5 promoter in DE3 region of λ phage, which is integrated on the chromosome of BL21. The strain is suitable for the expression of nontoxic proteins.
