X-Gal is a chromogenic substrate of b-Galactosidase. It is used in conjunction with IPTG for detection of b-Galactosidase activity in bacterial colonies in a colorimetric assay to detect recombinants (white) from non-recombinants (blue). X-Gal is cleaved at the b 1-4 bond between galactose and the…
