Thiazolyl Blue (MTT) is a cell-permeable and positively charged tetrazolium dye that is used to detect reductive metabolism in cells. Thiazolyl Blue is taken up by cells through the plasma membrane and then reduced to formazan by intracellular NAD (P) H-oxidoreductases. Thiazolyl Blue is frequently used in colorimetric assays to measure cell proliferation, cytotoxicity, and apoptosis .

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 .

4-Aminophenyl-β-D-galactopyranoside, 98% is a highly efficient substrate for β-galactosidase. It is specifically hydrolyzed by this enzyme to release galactose and electroactive p-aminophenol. 4-Aminophenyl-β-D-galactopyranoside, 98% is widely used in colorimetric and electrochemical assays for detecting β-galactosidase activity and determining enzyme kinetics, such as in biosensing fields including cellular senescence, pathogen and contaminant detection. In addition, since β-galactosidase is often overexpressed in primary ovarian cancer, 4-Aminophenyl-β-D-galactopyranoside, 98% can also be applied to related research on primary ovarian cancer .

Potassium p-nitrophenyl sulfate (4-Nitophenyl Sulfate potassium) serves as a chromogenic substrate for arylsulfatases. Potassium p-nitrophenyl sulfate releases nitrophenol under the cleavage action of arylsulfatases, and the activity of arylsulfatases can be quantitatively determined via colorimetric detection at 400 nm. Potassium p-nitrophenyl sulfate is commonly used in enzyme inhibition assays and metabolite analog-related studies .
