AB 5-alpha chemically competent E.coli cells are comparable to the DH5_ªÊstrain of E. coli. AB 5-alpha cells carry recA1 and endA1 mutations that minimize recombination and improve plasmid stability and quality. They also contain aÊlacZ marker that provides _-complementation of the _-galactosidase gene for blue/white color screening and are ideal for cloning, sub-cloning, library construction, and plasmid isolation.
