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 .

CAS No.: 146797-82-2
Arachidonoyl Thio-PC is a substrate of many phospholipase A2 (PLA2), including sPLA2, cPLA2 and iPLA2. Cleavage of sn-2 fatty acids by PLA2 results in the production of free thiols, which react with chromogenic reagents such as DTNB (Ellman's reagent) and DTP, allowing quantification of PLA2 activity. Isozyme-specific cPLA2 activity can be measured by depleting or inhibiting sPLA2 and iPLA2 activity in the assay.
