Species enclosed in parentheses are predicted to react based on 100% sequence homology. Species cross-reactivity is determined by Western blot.
Specificity / Sensitivity
Caspase-9 Antibody detects endogenous levels of full length caspase-9 (47 kDa) and large fragments of caspase-9. The antibody does not recognize other caspases.
Source / Purification
Polyclonal antibodies are produced by immunizing rabbits with a synthetic peptide (KLH-coupled) corresponding to residues surrounding aspartic acid 315 of human caspase-9. Antibodies are purified by protein A and peptide affinity chromatography.
Western Blotting
Western blot analysis of HeLa cells, untreated, staurosporine-treated (1 µM) or cytochrome c-treated (0.25 mg/ml), and Jurkat cells, untreated or cytochrome c-treated, using Caspase-9 Antibody (Human Specific).
Flow Cytometry
Flow cytometric analysis of Jurkat cells, untreated (blue) or etoposide-treated (green), using Caspase-9 Antibody (Human Specific) compared to a nonspecific negative control antibody (red).
Background
Caspase-9 (ICE-LAP6, Mch6) is an important member of the cysteine aspartic acid protease (caspase) family (1,2). Upon apoptotic stimulation, cytochrome c released from mitochondria associates with the 47 kDa procaspase-9/Apaf 1. This complex processes procaspase-9 into a large active fragment (35 kDa or 17 kDa) and a small fragment (10 kDa) by self-cleavage at Asp315 (3-5). Cleaved caspase-9 further processes other caspase members, including caspase-3 and caspase-7, to initiate a caspase cascade, which leads to apoptosis (6-9). In addition to self-cleavage, procaspase-9 can also be cleaved in vivo by caspase-3 at Asp330. This process serves as positive feedback to amplify the apoptotic signal in the caspase activation pathway (3-5).
