Caspase-9 Antibody (Human Spec

9502:

Flow , Western Blotting

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.

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide 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).

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).
