BL21 Competent Cells

BL21 competent cells are an all-purpose strain for high-level protein expression and easy induction.

High-level protein expression and easy induction

Can be used with non-T7 RNA polymerase protein expression systems

Allows the tightest control of protein expression for extremely toxic proteins

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.

This product is only available to U.S. Domestic Customers.

For research use only, not to be used in diagnostic procedures.
