BL21 Competent Cells

RUO

BL21 competent cells are an all-purpose strain for high-level protein expression and easy induction. The basic BL21 strain does not contain the T7 RNA polymerase gene and can be used with non-T7 RNA polymerase protein expression systems. BL21 has the tightest control of protein expression for extremely toxic proteins.
