4-Aminophenyl beta-D-galactopyranoside (PAPG, 4-APG) is used as a substrate for the development of beta-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 beta-galactosidase(s).[1][2] CAS No: 5094-33-7 Molecular Formula: C12H17NO6 Molecular Weight: 271.27 Appearance: White to off-white powder Purity: 90% (1H-NMR) Identity (IR): Conforms to structure Water: 5% Solubility (1% dH2O): Water, 50mg/ml.
