包装 1 g in poly tube 250 mg in poly bottle 5, 25 g in poly bottle 500 mg in poly tube Substrates Chromogenic substrate for β-galactosidase Application 2-Nitrophenyl β-D-galactopyranoside is an enzyme substrate used to detect lacZ activity and hence the presence of β-galactosidase. Biochem/physiol Actions β-galactosidase, breaks down lactose into galactose and glucose. β-Galactosidase is not lactose specific and can act on simple galactosides. 2-Nitrophenyl β-D-galactopyranoside hydrolysis results in the release of galactose and a yellow chromogenic compound. The test substrate does not depend on an induced or constitutive permease enzyme to enter the cell, therefore reactions are rapid and occur within a 24-hour period.
