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).

The antibodies were prepared from antisera of rabbits immunized with bovine serum albumin containing covalently bound p-aminophenyl-beta-D-galactopyranoside (APG) and purified by affinity chromatography on APG-containing ovalbumin immobilized by BrCN-activated Sepharose 4B. The antibodies possessed a selective specificity for APG and
