Product Information
- GalNAc-b-1,3-Gal-a-1,4-Gal-b-1,4-Glc-b-pNP
4-Nitrophenyl beta-galactoside (pNP-Gal) is a chromogenic substrate commonly used in enzymatic assays to detect and quantify the presence of beta-galactosidase. It is hydrolyzed by the enzyme to release 4-nitrophenol, which produces a yellow color that can be measured spectrophotometrically. Similarly, 4-Nitrophenyl beta-glucoside (pNP-Glc) can be used to assay beta-glucosidase activity. 4-Nitrophenyl beta-globotrioside (pNP-Glo) is a similar compound that has been designed as a substrate for glycosidases that cleave terminal beta-galactosyl-(1->3)-N-acetylgalactosamine residues. In these assays, the release of 4-nitrophenol can be measured to determine the activity of the enzyme under study. The use of chromogenic substrates like pNP-Glo allows for the rapid and reliable detection of glycosidase activity in a variety of biological samples.
