AB 5-alpha chemically competent 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.
AB 5-alpha chemically competent cells are supplied as a pack of 10 convenient 100 μl/tube aliquots.
