Takara X-alpha-Gal \250 mg

X-α-Gal is a chromogenic substrate used to detect α-galactosidase activity. In yeast, α-galactosidase is a secreted reporter that is expressed from the MEL1 gene in response to GAL4 activation. α-galactosidase accumulates in the media and hydrolyses X-α-Gal causing yeast colonies to turn blue. X-α-Gal can be used with MatchmakerGAL4-based products to confirm protein interactions.
