Protocol
Specificity / Sensitivity
Cleaved Caspase-9 (Asp353) Antibody detects endogenous levels of the 37kDa subunit of mouse caspase-9 only after after cleavage at aspartic acid 353. It does not cross-react with full length caspase-9 or with other caspases at endogenous levels. Non-specific proteins that are induced by apoptosis under certain conditions may be detected.
Species Reactivity:
Mouse
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Asp353 of mouse caspase-9. Antibodies are purified by protein A and peptide affinity chromatography.
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. Apaf-1 mediated activation of caspase-9 involves intrinsic 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).
