Beta-Galactosidase Assays
β-galactosidase, also called beta-gal or β-gal, is a hydrolase enzyme that catalyzes the hydrolysis of β-galactosides into monosaccharides. Substrates of different β-galactosidases include ganglioside GM1, lactosylceramides, lactose, and various glycoproteins. The β-galactosidase gene functions well as a reporter gene for two major reasons: its protein product is extremely stable and resistant to proteolytic degradation in cellular lysates, and most importantly, the enzyme is easily assayed.
