Description
4-Nitrophenyl α-D-galactopyranoside (PNP-alpha-D-Gal) is an artificial substrate of 4-nitrophenyl (pNP) glycopyranoside for detecting α-galactosidase activity. The amount of released pNP is significantly increased when 4-Nitrophenyl α-D-galactopyranoside is used as substrates[1].
4-nitrophenyl alpha-D-galactoside is an alpha-D-galactopyranoside having a 4-nitrophenyl substituent at the anomeric position. It is an alpha-D-galactoside and a monosaccharide derivative.

Drug Information
Biologically active molecules which are covalently bound to the enzymes or binding proteins normally acting on them. Binding occurs due to activation of the label by ultraviolet light. These labels are used primarily to identify binding sites on proteins. (See all compounds classified as Photoaffinity Labels.)
