Characteristics 1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. Please refer to us for technical protocols.
3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
4. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
Purification The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.
Alternative Name Smac/DIABLO (DIABLO Antibody Abstract)
Background Apoptosis is a genetically programmed, selective process of cell death that occurs during normal cell differentiation and development of multicellular organisms. Inhibitors of apoptosis proteins (IAPs), hILP/XIAP, c-IAP1, c-IAP2, and survivin, suppress apoptosis by preventing procaspase activation and inhibiting mature caspase activity. Smac/DIABLO (second mitochondria-derived activator of caspases) eliminates the inhibitory effect of many IAPs, and has been shown to interact with hILP, c-IAP1, c-IAP2, and survivin. The interaction with hILP occurs through Smac/DIABLO binding to the second and third BIR domains of hILP. Smac/DIABLO protein contains an N-terminal mitochondria targeting sequence (MTS) and a procaspase-3 activation domain. The N-terminal MTS is cleaved after import into the mitochondria, and the activity of the mature Smac/DIABLO is dependent on homodimerization and release from the mitochondria. Overexpression of Smac/DIABLO in HeLa cells increases the sensitivity to UV-mediated apoptosis. Thus, Smac/DIABLO acts as an apoptotic activator through its binding to IAPs and activation of caspases.
