Cathepsin G Activity Assay Kit (Colorimetric)

Cathepsin G Activity Assay Kit (Colorimetric) (ab126780) is an assay where Cathepsin G will cleave the substrate and release the dye group, p-NA (4-Nitroaniline), which can be detected at 405 nm. In presence of the Cathepsin G specific inhibitor, the cleavage will be stopped. The kit provides a rapid, simple, sensitive, and reliable test for the activity of Cathepsin G.

Cathepsin G is an enzymatic protein belonging to the peptidase or protease families. The protein is found in azurophil granules of neutrophilic polymorphonuclear leukocytes. The encoded protease has a specificity similar to that of chymotrypsin C, and may participate in the killing and digestion of engulfed pathogens, and in connective tissue remodeling at sites of inflammation.
