Description

IPTG is a gratuitous beta-D-galactosidase inducer. In Escherichia coli IPTG functions by binding to the lac repressor and altering its conformation. This inactivation prevents the repressor binding to the operator of the lac operon and thus the repression of the beta-galactosidase coding gene lacZ. IPTG is a commonly used reagent in cloning procedures that require induction of beta-galactosidase activity and is used in conjunction with X-Gal or Lapis-β-D-Gal in blue-white color selection of recombinant bacterial colonies.
