|Application ||WB, IHC|
|Calculated MW||46281 Da|
|Other Names||Caspase-9, CASP-9, Apoptotic protease Mch-6, Apoptotic protease-activating factor 3, APAF-3, ICE-like apoptotic protease 6, ICE-LAP6, Caspase-9 subunit p35, Caspase-9 subunit p10, CASP9, MCH6|
|Target/Specificity||A synthetic peptide corresponding to C-terminus of human Caspase-9 p35 subunit was used as immunogen. The antibody should recognize only pro-form (46kDa) .|
|Format||50 mM Tris-Glycine (pH 7.4), 0.15 M NaCl, 40% Glycerol, 0.01% sodium azide and 0.05% BSA.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||Caspase-9 Antibody (Pro) is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||Involved in the activation cascade of caspases responsible for apoptosis execution. Binding of caspase-9 to Apaf- 1 leads to activation of the protease which then cleaves and activates caspase-3. Promotes DNA damage-induced apoptosis in a ABL1/c-Abl-dependent manner. Proteolytically cleaves poly(ADP- ribose) polymerase (PARP).|
|Tissue Location||Ubiquitous, with highest expression in the heart, moderate expression in liver, skeletal muscle, and pancreas. Low levels in all other tissues. Within the heart, specifically expressed in myocytes.|

Caspase-9 (ICE-LAP6, Mch-6, Apaf-3) is a member of the cysteine aspartic acid protease, or caspase, family. Pro-Caspase-9 exists as a 46 kDa isomer that is cleaved by apoptotic stimulation, and functions as the major initiator caspase in programmed cell death, or apoptosis (1-4). Upon stimulation, cytochrome c is released from mitochondria, and associates with the Pro-Caspase-9/Apaf 1 complex. This complex in turn activates Pro-Caspase-9 by cleaving it into an active 35 kDa fragment and a small 10 kDa fragment (1,2). Activated Caspase-9 cleaves Caspase-3 as well as poly (ADP-ribose) polymerase (PARP) to initiate a caspase cascade and apoptosis (3,4).
