Our Abpromise guarantee covers the use of ab8114 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
IHC-P Use a concentration of 5 µg/ml.
ICC/IF Use a concentration of 5 µg/ml.
WB Use a concentration of 0.5 - 1 µg/ml. Predicted molecular weight: 25 kDa.Can be blocked with Smac / Diablo peptide (ab8380).


  • Function
    Promotes apoptosis by activating caspases in the cytochrome c/Apaf-1/caspase-9 pathway. Acts by opposing the inhibitory activity of inhibitor of apoptosis proteins (IAP).
  • Tissue specificity
    Ubiquitously expressed with highest expression in testis. Expression is also high in heart, liver, kidney, spleen, prostate and ovary. Low in brain, lung, thymus and peripheral blood leukocytes.
  • Domain
    The mature N-terminus mediates interaction with XIAP.
  • Cellular localization
    Mitochondrion. Released into the cytosol when cells undergo apoptosis.

  • ab8114 at 5µg/ml staining Smac/Diablo in human ovary tissue by IHC

  • ICC/IF image of ab8114 stained MCF7 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 (ab8114, 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.

Thank you for contacting us. I'm glad to hear you have been getting good staining with ab469. In order to help you obtain more intense staining would you mind filling in the form which I have attached to this email. It will allow me to more fully understand the protocol which you have been performing and any areas in which it may be worthwhile to optimise. Could you also answer the following questions: 1. which HRP conjugate have you been using (streptavidin-HRP? could you tell me the catalogue no. etc) 2. in what dilution have you been using the secondary antibody? ab8114 is supplied at a concentration of 1 mg/mL. The recommended working concentration of this antibody when using it for immunohistochemistry with paraffin embedded sections is 5 µg/ml. This equates to a dilution of 1/200. This is only a guideline and may need to be optimised for the staining which you are performing. I hope this information has been of help and look forward to your reply.

Same answer again I am afraid! To our knowledge, this antibody has yet to be tested in this application. All tested applications are specified on Abcam product datasheets. If you decide to go ahead and purchase this product, please let us know how you get on and in return we will forward a reward of your choice, typically an Amazon gift voucher
