Application Abreviews Notes
IHC-P 1/50. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
WB 1/5000. Detects a band of approximately 75 kDa (predicted molecular weight: 70 kDa).


  • 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.

    This blot was produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 2% Bovine Serum Albumin before being incubated with ab207526 overnight at 4°C. Antibody binding was visualised using ECL development solution ab133406.

  • IHC image of cIAP1 staining in a section of formalin-fixed paraffin-embedded normal human spleen tissue performed on a Leica BONDTM. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20mins.  The section was then incubated with ab207526, 1/50 dilution, for 15 mins at room temperature. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. The inset negative control image is taken from an identical assay without primary antibody.


    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.
