Calpain-Glo Protease Assay

The Calpain-Glo Protease Assay is a homogeneous, luminescent assay that measures calpain 1 (µ) and 2 (m) activities

The Calpain-Glo Protease Assay is a homogeneous, luminescent assay that measures calpain 1 (u) and 2 (m) activities. Calpains are a family of calcium-activated cysteine proteases involved in cleaving a wide variety of proteins. Calpains modulate the biological activities of their substrates via limited proteolysis. The Calpain-Glo Protease Assay provides a succinyl, proluminescent calpain substrate, Suc-LLVY-aminoluciferin, in a buffer system optimized for calpain and luciferase activities. The addition of the calpain reagent in an add-mix-measure format results in calpain cleavage of the substrate and rapid development of a glow-type luminescent signal produced by the luciferase reaction. The signal is proportional to the amount of calpain activity present. The assay is designed for use with purified enzyme preparations.
