Application

4-Aminophenyl β-D-galactopyranoside (PAPG, 4-APG) is used as a substrate for the development of β-galactosidase(s) (GUS)-dependent assay systems via the formation of an electroactive product. It may be used to create affinity matricies for the capture or purification of β-galactosidase(s).[1][2]
