Specificity
This antibody recognises Apaf1 (Apoptosis protease activating factor 1), the mammalian homologue of the CED-4 cell death protein in C. Elegans. Apaf1 binds to cytochrome C and caspase-9 leading to caspase-9 activation, resulting in the beginning of the proteolytic cascade characteristic of apoptosis. Apaf1 can also associate with caspase-4 and caspase-8. recognises a ~130 kDa band in western blots.
