FunctionCalcium-dependent cysteine proteinases, or calpains, are widely distributed in mammalian cells. There are 2 distinct molecular forms, calpains 1 and 2, which differ in the quantity of calcium required. Both calpains 1 and 2 are heterodimeric; each is composed of 1 heavy (about 80 kD), CAPN1 and CAPN2, respectively, and 1 shared light (about 30 kD) subunit, CAPNS1. The heavy subunit has a catalytic function, and the light subunit is regulatory (1).

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Calpain S1 antibody [EPR3324]; Immunohistochemistry staining of Calpain S1 in formalin-fixed, paraffin-embedded Human kidney tissue using 1/100 TA307652.
Flow Cytometry-Anti-Calpain S1 antibody [EPR3324](TA307652); Overlay histogram showing HeLa cells stained with TA307652 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody for 30 min at 22°C. The secondary antibody used was DyLight 488 goat anti-rabbit IgG (H+L) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was rabbit IgG (monoclonal) (1ug/1x10^6 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in HeLa cells fixed with 4% paraformaldehyde (10 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.
