Caspase-9 (C9) Mouse mAb

9508:

Western Blotting

Caspase-9 (C9) Antibody detects endogenous levels of the pro form of caspase-9 as well as cleaved fragments.

Monoclonal Antibody is produced by immunizing mice with a recombinant human caspase-9 protein.

Western Blotting

Western blot analysis of extracts from Jurkat cells (human), L929 cells (mouse), and C6 cells (rat), untreated or treated with staurosporine or cytochrome c as indicated, using Caspase 9 (C9) Mouse mAb.

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).
