X-Gal (Bromo-5-chloro-4-indolyl-3-ß-D-galactopyranoside)

Thermo Scientific X-Gal (5-bromo-4-chloro-3-indolyl-beta-D-galacto-pyranoside) is an inert chromogenic substrate for beta-galactosidase which hydrolyzes X-Gal into colorless galactose and 4-chloro-3-brom-indigo, forming an intense blue precipitate


Induction of the lacZ gene with IPTG leads to the hydrolysis of X-Gal and to the development of blue colonies.
