|Application ||IHC-P, E|
|Other Accession||AAC51678, 2330015|
|Reactivity||Human, Mouse, Rat|
|Calculated MW||141840 Da|
|Application Notes||Apaf1 antibody can be used for detection of Apaf1 by immunohistochemistry at 0.5 mg/mL. Apaf1 has not been confirmed for use in Western Blot.|
|Reconstitution & Storage||Apaf-1 monoclonal antibody can be stored at -20℃, stable for one year.|
|Precautions||Apaf-1 Antibody [5E11] 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|

Apaf-1 Monoclonal 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.
