Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting, IP=Immunoprecipitation
Specificity / Sensitivity
Cleaved Caspase-9 (Asp315) Antibody (Human Specific) detects endogenous levels of the 35 kDa large fragment of caspase-9 following cleavage at aspartic acid 315. The antibody does not react with full length caspase-9 or any other cleaved caspases.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Asp315 of human caspase-9. Antibodies are purified by protein A and peptide affinity chromatography.
Western blot analysis of extracts from Jurkat cells, untreated or cytochrome c-treated (0.25 mg/ml), and HeLa cells, untreated, staurosporine-treated (1 µM), or cytochrome c-treated (0.25 mg/ml), using Cleaved Caspase-9 (Asp315) Antibody (Human Specific) (upper) or Caspase-9 Antibody (Human Specific) #9502 (lower).
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. Apaf-1 mediated activation of caspase-9 involves instrinsic proteolytic processing resulting in cleavage at Asp315 and producing a p35 subunit. Another cleavage occurs at Asp330 producing a p37 subunit that can serve to amplify the apoptotic response (3-6). Cleaved caspase-9 further processes other caspase members, including caspase-3 and caspase-7, to initiate a caspase cascade, which leads to apoptosis (7-10).
