and Implications To investigate the antioxidant capacity of calcium lactate on m-calpain activity, porcine m-calpain was preincubated with various combinations of hydrogen peroxide (H 2 O 2 ), calcium chloride (CaCl 2 ), and/or different concentrations of calcium lactate (CaLac). The m-calpain was activated by CaLac, and the extent of m-calpain oxidation by H 2 O 2 was decreased with increasing CaLac concentrations. These results suggest that CaLac addition to early postmortem muscle may lead a
