Apoptosis or programmed cell death is a fundamental cellular process that is essential for normal tissue development and abnormal growth such as cancer, neurodegeneration, autoimmune diseases, and angiogenesis, etc.
Apoptosis is driven by specialized proteases known as caspases.
After the initial discovery of the first mammalian caspase 1 or ICE (interleukin 1 beta converting enzyme), a growing family of caspases 1-14 have been cloned and characterized.
Caspases are synthesized as inactive zymogen or proenzyme forms (30-55kD), which upon apoptotic stimulation are proteolytically processed (self or by other proteins) in a sequential manner into their active heterotetrameric forms.
The processed form consists of large subunit (17-20kD) and a small (10-12kD) subunits, which may associate to form an active enzyme.
Functionally active caspases initiate a proteolytic cascade, capable of cleaving and activating numerous cellular targets including PARP, G4-GDI, DFF, MEKK, etc.
On a functional basis, two categories of caspases have been defined: the initiator caspases (caspases-8, -9, and –10) are activated in the earlier phases of apoptosis, whereas the executioner caspases (caspases-3, -6, and –7) are activated by initiator caspases and are responsible for dismantling cellular components.
Caspases are widely distributed in various tissues and cells.
Caspase-9 (rat/mouse 454 aa; human 416-aa, also known as apoptotic protease activating factor 3 (APAF-3)/ICE-like apoptotic protease 6 or ICE-LAP6 or MCH-6, is 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.
ELISA: Control peptide can be used to coat ELISA plates at 1ug/ml and detected with antibodies (1:10-50K)
Optimal dilution determined by the researcher.
