應用
4-Nitrophenyl β-D-galactopyranoside has been used:
- as a substrate to assess the activity of glycosaminoglycan (GAG)-degrading enzymes
- as a substrate to study the kinetic properties of recombinant Leuconostoc mesenteroides glycosidase (BgLm1) and determine β-glucosidase activity
- to prepare substrate solution in a modified universal buffer

alpha-Galactosidase (alpha-D-galactoside galactohydrolase, EC 3.2.1.22) from watermelon was covalently immobilized on chitin. The immobilized alpha-galactosidase exhibited an activity of 0.61 U per g of carrier and an activity yield of 67%. The properties of free and immobilized alpha-galactosidase were also

Enzymes are often quantified by measuring their biological activity. Capillary electrophoresis is gaining its position in this field due to the ongoing trend to miniaturize biochemical assays. The aim of this work was to compare pre-capillary (off-line) and in-capillary electrophoresis

This experiment was designed to synthesize 18 kinds of polyhydroxybenzophenones by using Friedel-Crafts reaction, and to measure the inhibitory activity on α-glucosidase with p-nitrophenyl-β-D-galactopyranoside (PNPG) as a substrate. Here, acarbose (IC(50) = 1674.75 µmol L(-1) ) was used as the reference
