Datasheet: X-gal
Description:
X-Gal (5-bromo-4-chloro-3-indolyl-beta-D-galactopyranoside) is a noninducing chromogenic substrate for beta-galactosidase, which hydrolyzes X-Gal forming an intense blue precipitate. X-GaI is most frequently used in conjunction with IPTG in blue/white colony screening to detect recombinants (white) from non-recombinants (blue). It is also utilized for selection of beta-galactosidase reporter gene activity in transfection of eucariotic cells and for detection of beta-galactosidase in immunology and histochemistry applications.
Quality Control:
Purity of >98% by HPLC. Tested in the blue/white colony screening experiment.
