Application Abreviews Notes
Flow Cyt Use 2µg for 106 cells.

ab170190 - Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.


ELISA Use at an assay dependent concentration.
ICC/IF Use at an assay dependent concentration.
WB 1/1000. Detects a band of approximately 35 kDa (predicted molecular weight: 26 kDa).
IHC-P 1/100.
IHC-Fr Use at an assay dependent concentration.


  • Function
    Protect the extracellular space from toxic effect of reactive oxygen intermediates by converting superoxide radicals into hydrogen peroxide and oxygen.
  • Tissue specificity
    Expressed in blood vessels, heart, lung, kidney and placenta. Major SOD isoenzyme in extracellular fluids such as plasma, lymph and synovial fluid.
  • Sequence similarities
    Belongs to the Cu-Zn superoxide dismutase family.
  • Cellular localization
    Secreted > extracellular space. 99% of EC-SOD is anchored to heparan sulfate proteoglycans in the tissue interstitium, and 1% is located in the vasculature in equilibrium between the plasma and the endothelium.

  • Anti-Superoxide Dismutase 3 antibody [4G11G6] (ab80946) at 1 µg/ml + Lung (Mouse) Tissue Lysate at 10 µg

    Goat Anti-Mouse IgG H&L (HRP) preadsorbed (ab97040) at 1/5000 dilution

    Developed using the ECL technique.

    Performed under reducing conditions.

    Predicted band size: 26 kDa
    Observed band size: 25 kDa (why is the actual band size different from the predicted?)
    Additional bands at: 54 kDa. We are unsure as to the identity of these extra bands.

    Exposure time: 1 minute
  • ab80946 at 1/100 dilution staining Superoxide Dismutase 3 in human cartilage by Immunohistochemistry (Bouin's fixative fixed paraffin-embedded tissue section). Antigen retrieval was done by microwave in citrate buffer. A HRP-conjugated anti mouse secondary was used at 1/10 dilution. Image 'a' repersents control, 'b' staining of tissue from young human cartilage and 'c' show staining cartilage of a person suffered from osteoarthritis. 

  • Overlay histogram showing HEK293 cells stained with ab80946 (red line). The cells were fixed with 80% methanol (5 min) and incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab80946, 2µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.

    Please note that Abcam do not have any data for use of this antibody on non-fixed cells. We welcome any customer feedback.
