Chlorophenol red β-D-galactopyranoside sodium
β-Galactosidase Subtrate
Chlorophenol red β-D-galactopyranoside sodium is a chromogenic substrate specifically designed for the enzyme β-galactosidase. Upon hydrolysis by β-galactosidase, it releases chlorophenol red, resulting in a color transition from pale yellow to purple-red in neutral to alkaline conditions. This shift can be quantitatively assessed through spectrophotometric analysis at wavelengths of 540-572 nm, making it an invaluable tool for colorimetric assays in enzyme activity studies and related research applications.
