Application Abreviews Notes
IHC-P 1/100. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.


  • Function

    Inhibits the activity of interleukin-1 by binding to receptor IL1R1 and preventing its association with the coreceptor IL1RAP for signaling. Has no interleukin-1 like activity. Binds functional interleukin-1 receptor IL1R1 with greater affinity than decoy receptor IL1R2; however, the physiological relevance of the latter association is unsure.
  • Tissue specificity

    The intracellular form of IL1RN is predominantly expressed in epithelial cells.
  • Involvement in disease

    Microvascular complications of diabetes 4
    Interleukin 1 receptor antagonist deficiency
  • Cellular localization

    Cytoplasm and Secreted.

  • IHC image of IL-1RA staining in a section of formalin-fixed paraffin-embedded human normal kidney*, performed on a Leica BondTM. The section was pre-treated using pressure cooker heat mediated antigen retrieval with sodium citrate buffer (pH6) for 30mins before blocking of endogenous biotin using ab64212. The section was then incubated with ab205855, 1/100 dilution, for 15 mins at room temperature and detected using an HRP conjugated ABC system. 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.
