5-alpha Electrocompetent E. coli Cells
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.
