Tribo™ DH5α Competent Cells are an E. coli strain DH5α that provides high transformation efficiencies. Cells can be used in a wide variety of applications for cloning and subcloning. The lacZΔM15 marker provides α-complementation of the β-galactosidase gene, allowing blue/white screening of colonies on plates containing X-gal or Bluo-gal. DH5α competent cells support the replication of M13mp vectors but do not support plaque formation.
