4-Nitrophenyl 2-O-(a-L-fucopyranosyl)-b-D-galactopyranoside

Fuc-a-1-2-Gal-b-PNP

4-Nitrophenyl 2-O-(a-L-fucopyranosyl)-b-D-galactopyranoside is a chromogenic enzymatic substrate for the detection and quantification of glycosidases, such as fucosidases and galactosidases. Upon enzymatic cleavage, the substrate releases the p-nitrophenol chromophore, which can be quantified via colorimetric analysis. This pNP-conjugated compound enables the rapid, sensitive, and high-throughput detection of enzyme activity in various applications, including enzymatic assays, inhibitor screening, and mechanistic studies. Its precise specificity for a-L-fucopyranosyl and b-D-galactopyranoside moieties makes it an excellent tool for advancing research in glycobiology and related fields.
