Product Description: Calpains are a family of cysteine proteases involved in the regulation of many protein substrates via limited proteolysis in
response to calcium signaling. This feature of calpains notably differs from proteasomes and autophagy, both of which degrade their protein
substrates. Two well-characterized members of the conventional calpain family in mammals are calpain 1 (mu isoform) and 2 (m isoform), which
are heterodimers of a specific 80-kDa large subunit and a common 28-kDa small subunit. Calpains have been implicated in numerous
calcium-regulated processes such as cell motility, cell cycle progression, cell death, and differentiation, making them ideal therapeutic targets.
The Calpain Assay Kit is derived from a modified colorimetric method (Arch Biochem Biophys 319:211,1995) for semi-quantitative analysis of
calpain activity in purified or crude samples. Casein is used as substrate in the assay kit and its breakdown is monitored by a protein-binding dye
present in Calpain Assay Solution. Sample calpain activity is measured by O.D.595nm. The kit is stable for at least one year under proper
storage and handling conditions.
