Invitrogen™ BL21-AI™ One Shot™ Chemically Competent E. coli

Invitrogen™ BL21-AI™ One Shot™ Chemically Competent E. coli

One Shot® BL21-AI™ E. coli are chemically competent cells designed for applications that require tight regulation and strong expression of toxic proteins from any T7 promoter-based expression systems. One Shot® BL21-AI™ Chemically Competent cells have a transformation efficiency of >1×108 cfu/ µg plasmid DNA.

Features

• Ideal for inducing expression of toxic protein
• Gene expression is regulated by the addition of L-arabinose to culture
• Suitable for use with any T7 promoter-based plasmids
• Supplied in a convenient One Shot® format

Contents

• BL21-AI™ Chemically Competent E. coli are provided in single-use, 50-µl aliquots, with S.O.C. medium and supercoiled control plasmid.
