5-alpha Electrocompetent E. coli Cells | Amid Biosciences
High efficiency electrocompetent AB 5-alpha E.coli cells are comparable to the DH5α™ strain of E. coli. AB 5-alpha cells carry recA1 and endA1 mutations that minimize recombination and improve plasmid stability and quality. They also contain a lacZ marker that provides α-complementation of the β-galactosidase gene for blue/white color screening and are ideal for cloning, sub-cloning, library construction, and plasmid isolation. Transformation efficiency ≥ 1x1010 cfu/μg pUC19 plasmid DNA.
E. coli genotype: F- endA1 recA1 relA1 gyrA96 hsdR17(rk-, mk+) deoR supE44 phoA Δ(lacZYA-argF) U169 Φ80lacZΔM15 λ– thi-1
