One Shot® BL21 Star™ (DE3) Chemically Competent E. coli

Category: Products & Services > Competent Cells & Strains > Expression Competent Cells

One Shot® BL21 Star™ (DE3) E. coli are chemically competent cells designed for applications that require high-level expression of non-toxic recombinant proteins from low copy number, T7 promoter-based expression systems (e.g., Champion™ pET vectors) . One Shot® BL21 Star™ (DE3) Chemically Competent cells are controlled for a transformation efficiency of 1 x 10 8 cfu/ µg plasmid DNA. • A genotype that promotes high mRNA stability and protein yield • Ideal for use with low copy number, T7 promoter-based plasmids • The single tube, single use format allows all transformation steps to take place i...
