Our Abpromise guarantee covers the use of ab2399 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. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
WB Use a concentration of 1 - 4 µg/ml. Detects a band of approximately 72 kDa (predicted molecular weight: 69 kDa).Can be blocked with cIAP1 peptide (ab38272).


  • Function
    Apoptotic suppressor. The BIR motifs region interacts with TNF receptor associated factors 1 and 2 (TRAF1 and TRAF2) to form an heteromeric complex, which is then recruited to the tumor necrosis factor receptor 2 (TNFR2).
  • Tissue specificity
    Present in many fetal and adult tissues. Mainly expressed in adult skeletal muscle, thymus, testis, ovary, and pancreas, low or absent in brain and peripheral blood leukocytes.
  • Sequence similarities
    Belongs to the IAP family.
    Contains 3 BIR repeats.
    Contains 1 CARD domain.
    Contains 1 RING-type zinc finger.

  • Anti-cIAP1 antibody (ab2399) + Jurkat Cell lysate

    Predicted band size: 69 kDa
    Observed band size: 70 kDa
    why is the actual band size different from the predicted?

  • IHC image of ab2399 staining in human tonsil formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab2399, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

Thank you for your email.

The peptide is from the sequence around amino acid 530 of human cIAP1. This sequence does not match with the immunogen sequence of polyclonal and monoclonal antibodies you have so this peptide ab38272 would be of no use.

If you are interested in doing blocking experiment then ab38272 would block ab2399.

I hope this information will be helpful. Should you have any question please do not hesitate to contact me.

Thank you for contacting us.

Could you please explain what do you mean by other antibodies? The antibodies against the same peptide should be same however difference can be seen in specificity, purity etc.

The peptide ab38272 is from a sequence flanking 530 of human cIAP1. We unfortunately don't know the exact sequence so this peptide may not able to block your antibody.

Do you know the immunogen sequence of your antibody?

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Thank you for your phone call. I am very sorry to hear that these 3 antibodies are not providing satisfactory results. The details provided will enable us to investigate these 3 cases and will provide us with vital information for monitoring product quality. I appreciate the time you have spent in the laboratory and understand your concerns. It is regrettable the results have not been successful. As we discussed, I believe these 3 products should have given satisfactory results. It appears that you may have received either faulty vials, or the shipment was affected by temperature variations, customs or other unknown factors. I apologize very much for the inconvenience, but am pleased to let you know that I have arranged for the replacement shipment as we discussed. Thank you for your understanding. I wish you good luck with your research! Please let me know if there is anything else I can help you with.

Thank you for your inquiry. We source this antibody from an outside laboratory, and unfortunately we do not have access to the exact sequence used for the immunogen. If you plan to use the antibody on a fragment of the protein, we may be able to get more specific information of whether this antibody would bind to your fragment, but unfortunately we don't have access to any further information than what is on the datasheet. I apologize that I cannot be more help
