2-Nitrophenyl-β-D-galactopyranoside
2-Nitrophenyl-β-D-galactopyranoside or ONPG is a chromogenic substrate for β-galactosidase. Upon hydrolysis, ONPG releases galactose along with a chromogenic yellow compound. Additionally, ONPG is a substrate useful for the determination of β-glucosidases.Product Specifications2-Nitrophenyl-β-D-galactopyranosideo-Nitrophenyl-beta-D-galactosideONP-beta-D-GalONPGFormula: C12H15NO8MW: 301.26 g/mol
