Overview

  • Product name
    Anti-Superoxide Dismutase 3 / EC-SOD antibody
    See all Superoxide Dismutase 3 / EC-SOD primary antibodies
  • Description
    Rabbit polyclonal to Superoxide Dismutase 3 / EC-SOD
  • Host species
    Rabbit
  • Specificity
    Specific to human extracellular SOD (SOD3). Under reducing conditions the SOD3 antibody shows a major band at approximately 30kDa which is the approximate molecular weight of the SOD3 monomer and two faint minor bands at approximately 50 and 70 kDa. The SOD3 molecule is a homotetramer (4 monomers) with a combined molecular weight of around a 130 Kda. The two faint bands are probably dimers and triplicates of the monomer. This pattern is common with many tetramers (such as cellular glutathione peroxidase) as there is incomplete reduction with DTT.

Properties

Applications

Our Abpromise guarantee covers the use of ab21974 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IHC-Fr 1/200 - 1/2000.
IHC-P Use at an assay dependent concentration.
WB 1/1000 - 1/4000. Detects a band of approximately 31 kDa (predicted molecular weight: 26 kDa).

Target

  • 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.

    Developed using the ECL technique.

    Performed under reducing conditions.

    Predicted band size: 26 kDa
    Observed band size: 31 kDa
    why is the actual band size different from the predicted?
    Additional bands at: 75 kDa. We are unsure as to the identity of these extra bands.


    Exposure time: 30 seconds


    Superoxide Dismutase 3 / EC-SOD contains a number of potential glycosylation sites (SwissProt) which may explain its migration at a higher molecular weight than predicted.
