Our Abpromise guarantee covers the use of ab2000 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
ICC/IF Use a concentration of 5 µg/ml.
IHC-P Use a concentration of 20 µg/ml.
WB 1/500 - 1/2000. Predicted molecular weight: 130 kDa.Can be blocked with APAF1 peptide (ab7872).


  • FunctionOligomeric 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 specificityUbiquitous. 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.
  • Sequence similaritiesContains 1 CARD domain.
    Contains 1 NB-ARC domain.
    Contains 13 WD repeats.
  • DomainThe CARD domain mediates interaction with APIP.
  • Cellular localizationCytoplasm.

Anti-APAF1 antibody images

  • ICC/IF image of ab2000 stained HEK293 cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab2000, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
