StorageMaintain 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.
PrecautionsCaspase-9 Antibody (Pro) is for research use only and not for use in diagnostic or therapeutic procedures.
Protein Information
Name CASP9
Synonyms MCH6
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).
