Application Abreviews Notes
WB Use a concentration of 1 µg/ml. Detects a band of approximately 32 kDa (predicted molecular weight: 26 kDa).


  • 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.

    Performed under reducing conditions.

    Predicted band size: 26 kDa
    Observed band size: 32,35 kDa
    why is the actual band size different from the predicted?
    Additional bands at: 110 kDa, 42 kDa, 50 kDa, 55 kDa, 60 kDa. We are unsure as to the identity of these extra bands.

    Exposure time: 4 minutes

    Superoxide dismutase 3 / EC-SOD contains a number of potential glycosylation sites (SwissProt), which may explain the migration pattern observed.
