Molecular Biology Grade

4-Aminophenyl-β-D-galactopyranoside is a substrate for β-galactosidase. It is also a weak β-D-galactosidase inducer and can be used in affinity chromatography for isolation of galactose-binding. The 4-aminophenyl releases upon cleavage by β-galactosidase. It can then be assayed by electro-oxidation to 4-imino quinone while recording changes in the potential or current galvanic system.
