o-Nitrophenyl-β-D-galactoside is a cell culture component for molecular genetics. It is chromogenic substrate for b-galactosidase and hence is useful in the detection of lacZ activity.
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.
