BL21 Chemically Competent Cell is specifically designed for chemical transformation of DNA. It is resistant to tetracycline (TetR) and permits a transformation efficiency of over 107 cfu/μg DNA (tested by pUC19 plasmid DNA).


E. coli B F- dcm omp T hsdS(rB-mB-) gal [malB+]K-12(λ S)


• Transformation efficiency: >107 cfu/μg (pUC19 DNA).
• TetR.
• Tight expression control ideal for toxic protein expression.
• Control plasmid II (Amp+) is used for detection of expression function of cell. The protein size is about 26 kDa.
