| Product Description: | Mouse Monoclonal anti-Calpain 1 (107-82) |
| Clone: | 107-82 |
| Clonality: | Monoclonal |
| ListPrice: | 285 |
| Immunogen: | Purified bovine skeletal muscle 80 kDa subunit of M Calpain. |
| Epitope: | This antibody recognizes an epitope between amino acids 502-699 (domain III / IV) of human M Calpain. |
| Specificity: | 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 cultured pig cells. This antibody does not cross-react with Mu Calpain, N Calpain, calmodulin or calpastatin. |
| Cross Reactivity: | Cross-reacts with Human, Rat, Cow and Pig. Not yet tested in other species. |
| Packaging: | 0.1 ml purified Mouse ascites. |
| Uses: | Western blot: use at a dilution of 1/500.Immunocytochemistry: use at a dilution of 1/50.FACS: use at a dilution of 1/50.Not tested in other applications.Optimal dilutions / concentrations should be determined by the end user.By Western blot, this antibody detects an ~80 kDa protein representing M Calpain in bovine platelets. Immunocytochemical staining of M Calpain in LLC-PK1 cells results in diffuse cytoplasmic staining. |
| Localization: | Cytoplasmic. Cell membrane. Translocates to the plasma membrane upon Ca(2+) binding. |
| 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, and 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. |
