    CPRG

    Biochemical Assay Reagents Others
    Chlorophenol red-β-D-galactopyranoside (CPRG) is an efficient and sensitive chromogenic substrate for β-galactosidase (HY-P2869), widely used in colorimetric assays. Chlorophenol red-β-D-galactopyranoside 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 .
