Chlorophenol red β-D-galactopyranoside sodium

Overview

Chlorophenol red-β-D-galactopyranoside (CPRG) sodium is an efficient and sensitive chromogenic substrate for β-galactosidase ( HY-P2869 ), widely used in colorimetric assays. Chlorophenol red-β-D-galactopyranoside sodium itself appears pale yellow. When it is specifically hydrolyzed by β-galactosidase, it releases chlorophenol red. The released chlorophenol red turns purple-red under alkaline or neutral pH conditions. This color change from yellow to red can be quantitatively detected at wavelengths of 540-572 nm using visible spectrophotometry.
