目标/特异性 | Cleaved Caspase-9 (Asp353) Antibody (Mouse Specific) 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. |

背景 | 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. Additional 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). |
