Takara X-alpha-Gal \250 mg

Takara X-Gal is a chromogenic substrate used to detect -galactosidase activity. In yeast, -galactosidase is a secreted reporter that is expressed from the MEL1 gene in response to GAL4 activation. -galactosidase accumulates in the media and hydrolyses X-Gal causing yeast colonies to turn blue. X-Gal can be used with Matchmaker GAL4-based products to confirm protein interactions. - TAKBGN (Additional S&H or Hazmat Fees May Apply)
