Overview
Calpain-1 (μ-Calpain) is a calcium activated neutral cysteine protease. It is a heterodimer of a Catalytic 80 kDa subunit and a 30 kDa subunit, which requires 50 μM Ca2+ for half-maximal activity in vitro. Its participation in events such as cell division, signal transduction, and long term potentiation has been suggested. Calpains have also been proposed to play a role in various pathological processes associated with altered metabolism and altered calcium homeostasis.
Prepared from whole blood shown to be non reactive for HBsAg, anti-HCV, anti-HBc, and negative for anti-HIV 1 & 2 by FDA-required tests.
