  • Immunohistochemical analysis of formaldehyde-fixed paraffin-embedded murine obsese nephric tissue sections, labelling IL18 with ab71495 at a dilution of 1/2500 incubated for 12 hours at 4°C in PBS and 2.5% horse serum diluent. Heat mediated antigen retrival was with citrate buffer and blocking was with 2.5% horse serum in PBS incubated for 1 hour at 25°C. Secondary was a horse anti-rabbit polyclonal HRP conjugate.

  • Anti-IL18 antibody (ab71495) at 1 µg/ml + Mouse spleen tissue lysate at 10 µg

    Goat Anti-Rabbit IgG H&L (HRP) preadsorbed (ab97080) at 1/5000 dilution

    Developed using the ECL technique.

    Performed under reducing conditions.

    Predicted band size: 22 kDa
    Observed band size: 22 kDa
    Additional bands at: 100 kDa, 150 kDa, 76 kDa. We are unsure as to the identity of these extra bands.

    Exposure time: 2 minutes
  • IHC image of ab71495 staining in mouse normal spleen 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 ab71495, 1µg/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.
