Mouse anti-M Calpain (Human/Mouse/Rat/Bovine/Porcine)
cat# RDI-MCALPNabMX $469.00
Presentation: 100ul of ascites containing 0.05% sodium azide.
Clone: 107-82
Isotype: Mouse IgG1
Immunogen: Purified bovine skeletal muscle 80 kDa subunit of m-calpain
Storage: -20° C, Avoid Freeze/Thaw Cycles
Use/Dilution: FACS 1:50
Immunocytochemistry 1:50
Western Blot 1:500
Data: detects the 80 kDa subunit of m-calpain in human platelets and erythrocytes, bovine platelets, heart and skeletal muscle, rat myoblasts, kidney, liver and spleen, and pig cultured cells. This antibody does not cross-react with u-calpain, n-calpain, calmodulin or calpastatin. This Mab has been successfully used in Western blot, immunocytochemistry and FACS procedures. By Western blot, this antibody detects an ~80 kDa protein representing m-calpain in bovine platelets. Immunocytochemical staining of mu-calpain in LLC-PK1 cells with MA3-942 results in diffuse cytoplasmic staining. This product has not been shown to be effective in immunoprecipitation experiments.
-This antibody recognizes an epitope between amino acids 502-699 (domain III/IV) of human calpain.
background: The calpain (calcium-dependent protease or calcium-activated neutral protease) system consists of two ubiquitous forms of calpain (mu-calpain and m-calpain), a tissue specific calpain (n-calpain), and a calpain inhibitory protein (calpastatin). The calpain system has been detected in every vertebrate tissue examined, andcontinued on back side has been suggested to play a regulatory role in cellular protein metabolism. This regulatory role may have important implications in platelet aggregation and pathologies associated with altered calcium homeostasis and protein metabolism such as ischemic cell injury and degenerative diseases. Inhibitors of calpain have been shown to block dexamethasone and low-level irradiation induced apoptosis in thymocytes suggesting that calpain has a regulatory or mechanistic role in apoptotic cell death.
Mu- and m-calpains are heterodimers consisting of 28 kDa and 80 kDa subunits. The 28 kDa subunit is identical in the two isoforms, but the 80 kDa subunits differ with ~50% sequence similarity. 28 kDa/80 kDa complexes are thought to be inactive proenzymes which, upon binding of calcium, undergo conformational changes that promotes cleavage of the 28 kDa subunit and results in enzyme activation.

Rabbit anti-M Calpain C term(Human/Mouse/Rat)
cat# RDI-MCALPNCabRX $469.00
Presentation: 100 ug of epitope affinity purified IgG (1 mg/ml) in PBS containing sodium azide and 50% glycerol
Host: Rabbit IgG
Immunogen: Synthetic peptide based on the C-terminal region from human m-calpain.
Storage: -20° C, Avoid Freeze/Thaw Cycles
Use/Dilution: ELISA: Assay dependent
Immunohistochemistry: Assay dependent
Immunoprecipitation: Assay dependent
Western Blot 1:5,000
Data: -detects m-calpain from human, mouse and rat samples.
-has been successfully used in Western blot, immunohistochemistry, immunoprecipitation and ELISA procedures. By Western blot, this antibody detects 80 and 58 kDa proteins representing m-calpain, as well as a series of further cleaved isoforms.
Background: Mu-Calpain, also known as Calpain-I, and m-calpain, also known as Calpain-II, are intracellular, calcium-dependent cysteine proteases. Mu-calpain has a micromolar sensitivity (thus the mu-) as compared to the millimolar calcium sensitivity of m-calpain. The calpains have papain-like activity, thus the -pain nomenclature. Both m-calpain and mu-calpain are ubiquitously expressed, and are countered by the endogenous calpain inhibitor, calpastatin. Other calpain family members (calpain-94, ncl-2, ncl-3, etc) have more limited tissue distribution, and perhaps different functions. The calpain family members consist of a common small subunit (Calpain-4), and a large variable subunit. It is not clear that all calpains contain a small subunit. Domains in the large subunit include the amino terminal domain-I, the proteinase domain-II, domain-III, and the EF-hand domain-IV.
