Combo Pack of AB 5-alpha and BL21(DE3) Chemically Competent E.coli Cells

This Chemically Competent E.coli Cells Combo Pack allows fulfilling your cloning and protein expression needs. The Combo Pack contains 5 tubes of AB 5-alpha and 5 tubes of BL21(DE3) chemically competent E. coli cells in convenient packaging format (100 μl/tube aliquots). AB 5-alpha cells are directly comparable to DH5a™ cells. These cells are perfect for use in all cloning applications, including preparation of high-quality plasmid DNA. They offer efficient transformation even with large plasmids. The transformation efficiency is  ≥ 1x108 cfu/μg pUC19 plasmid DNA.  Applications Transformation of plasmids into bacterial cells Cloning, sub-cloning, library construction Blue/white color screening Catalog # CAB5BL21-201 Genotype: F- deoR endA1 recA1 relA1 gyrA96 hsdR17(rk-, mk+) supE44 thi-1 phoA Δ(lacZYA-argF)U169 Φ80lacZΔM15 λ- BL21(DE3) chemically competent E.coli cells are suitable for transformation, high-level protein expression and production of recombinant proteins in bacterial s
