|Application ||WB, IHC-P, E|
|Other Accession||AAC51678, 2330015|
|Reactivity||Human, Mouse, Rat|
|Calculated MW||130 kDa|
|Application Notes||Apaf1 antibody can be used for detection of Apaf1 by Western blot at 1 µg/mL. Human heart tissue lysate can be used as positive control and a 130 kDa band should be detected. Antibody can also be used for immunohistochemistry starting at 20 µg/mL.|
|Other Names||Apaf1 Antibody: CED4, APAF-1, KIAA0413, Apoptotic protease-activating factor 1, apoptotic peptidase activating factor 1|
|Reconstitution & Storage||Apaf1 antibody can be stored at 4℃ for three months and -20℃, stable for up to one year. As with all antibodies care should be taken to avoid repeated freeze thaw cycles. Antibodies should not be exposed to prolonged high temperatures.|
|Precautions||Apaf1 Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||Oligomeric Apaf-1 mediates the cytochrome c-dependent autocatalytic activation of pro-caspase-9 (Apaf-3), leading to the activation of caspase-3 and apoptosis. This activation requires ATP. Isoform 6 is less effective in inducing apoptosis.|
|Tissue Location||Ubiquitous. Highest levels of expression in adult spleen and peripheral blood leukocytes, and in fetal brain, kidney and lung. Isoform 1 is expressed in heart, kidney and liver|

Apaf1 Antibody: Apoptosis is related to many diseases and induced by a family of cell death receptors and their ligands. Cell death signals are transduced by death domain containing adapter molecules and members of the caspase family of proteases. The mammalian homologous of the key cell death gene CED-4 in C. elegans was identified recently from human and mouse and designated Apaf1 for apoptosis protease-activating factor 1. Apaf1 binds to cytochrome c (Apaf2) and caspase-9 (Apaf3), which leads to caspase-9 activation. Activated caspase-9 in turn cleaves and activates caspase-3 that is one of the key proteases, being responsible for the proteolytic cleavage of many key proteins in apoptosis. Apaf1 can also associate with caspase-4 and caspase-8. Apaf1 transcript is ubiquitously expressed in human tissues.
