X-alpha-Gal

X-alpha-Gal is a chromogenic substrate for alpha-galactosidase. Upon cleavage by alpha-galactosidase, a blue pigment is released that can be used as a marker of alpha-galactosidase activity. X-alpha-Gal has been used in the identification of S. cerevisiae and S. bayanus hybrid yeast.Formal Name: 5-bromo-4-chloro-1H-indol-3-yl alpha-D-galactopyranoside. CAS Number: 107021-38-5.
