5-Bromo-4-Chloro-3-Indolyl-?-D-Galactopyranoside
Application Notes
5-Bromo-4-chloro-3-indolyl b-D-galactopyranoside is used as indigogenic substrate for b - galactosidase, for detection of b - galactosidase-positive clones, and the identification of lac and bacterial colonies or phage plaques. X-Gal is a chromogenic substrate for ß-galactosidase that produces a rich blue color that can easily be detected visually over background. X-Gal is the substrate of choice for blue-white selection of recombinant bacterial colonies with the lac+ genotype.
