Synonyms: CPRG
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 .

MTT Formazan is a purple water-insoluble product formed by the reduction of yellow soluble MTT by succinate dehydrogenase in the mitochondria of viable cells. The amount of MTT Formazan produced is proportional to cellular metabolic activity, and it can serve as an indicator for evaluating cell viability and proliferation. MTT Formazan exhibits solvent-dependent solubility properties, and its absorbance value can be measured by spectrophotometry to reflect cellular status. MTT Formazan also supports the assessment of cell viability in bacterial MTT assays. MTT Formazan can be used in photoacoustic microscopy to enhance the imaging effect of viable cells, especially in applications in the fields of three-dimensional cell culture and tissue engineering .
