General description
Native calpain-1 from human erythrocytes. Ca2+-dependent cysteine proteinase with low Ca2+ requirement (half-maximal activation = 2 µM). Participates in the ATP release reaction of platelets stimulated with thrombin.
Packaging
Please refer to vial label for lot-specific concentration.
Physical form
In 20 mM imidazole, 5 mM β-mercaptoethanol, 1 mM EDTA, 1 mM EGTA, 30% glycerol, pH 6.8.
Preparation Note
Following initial thaw, aliquot and freeze (-70°C).
Prepared from blood that has been shown by certified tests to be negative for HBsAg and for antibodies to HIV and HCV.
Analysis Note
Comparable to reference lot by SDS-PAGE
Other Notes
One unit is defined as the amount of enzyme that will hydrolyze 1 pmol Suc-LLVY-AMC in 1 min, 25°C using the Calpain Activity Assay Kit, Fluorogenic (Cat. No. QIA120). Note: 1 caseinolytic unit = 1 fluorogenic unit.

Neuronal calcium sensor-1 (NCS-1) is a high-affinity, low-capacity Ca(2+)-binding protein expressed in many cell types. We previously showed that NCS-1 interacts with inositol 1,4,5-trisphosphate receptor (InsP(3)R) and modulates Ca(2+)-signaling by enhancing InsP3-dependent InsP(3)R channel activity and intracellular Ca(2+) transients. Recently

Endogenous fragments of p53 protein were identified in human cytomegalovirus (HCMV)-infected human lung fibroblasts, particularly a 44-kDa N-terminal fragment [hereafter referred to as p53(ΔCp44)], generated via calpain cleavage. The fragment abundance increased in a biphasic manner, peaking at 6-9 hours and
