  • Product overview

    Superoxide Dismutase Activity Assay Kit (Colorimetric) (ab65354) is a sensitive kit using WST-1 that produces a water-soluble formazan dye upon reduction with superoxide anion. The rate of the reduction with a superoxide anion is linearly related to the xanthine oxidase (XO) activity, and is inhibited by SOD. Therefore, the inhibition activity of SOD can be determined by a colorimetric method.

  • Notes

    Superoxide dismutase (SOD) is one of the most important antioxidative enzymes. It catalyzes the dismutation of the superoxide anion into hydrogen peroxide and molecular oxygen.

  • Research areas
  • Relevance
    Superoxide dismutase (SOD) is an antioxidant enzyme involved in the defense system against reactive oxygen species (ROS). SOD catalyzes the dismutation reaction of superoxide radical anion (O2-) to hydrogen peroxide, which is then catalyzed to innocuous O2 and H2O by glutathione peroxidase and catalase. Several classes of SOD have been identified. These include intracellular copper, zinc SOD (Cu, Zn SOD/SOD1), mitochondrial manganese SOD (Mn SOD/SOD2) and extracellular Cu, Zn SOD (EC SOD/SOD3).

Customer reviews and Q&As

The ab65354 Superoxide Dismutase Activity Colorimetric Assay Kit can be used without a standard since it is reporting as % inhibition in your sample. Blank 1 does not contain any inhibition, and your sample will have some percentage of inhibition. Bla...

I would not suggest this, as we store this product at 4C ourselves. We haven't tried to store this productat -20C, and we do not know if the product is suitable to be stored at lower temperatures. Please be aware that the customer will loose the Abprom...

The lower limit for this kit is 0.1 U/ml of SOD activity.

This kit is not originally designed to be run with a standard curve each time. However, if you wish to run a standard curve to calculate absolute activity (the assay is designed to calculate percent inhibition with respect to control sample), you can t...

I can confirm that there is nothing isoform-specific in the kit principle. ab65354 measures the oxygen anion created by any of the SOD enzymes.

The minimum mass of tissue to use with this assay is 10mg.

The graph we have on our datasheet has the % inhibition on Y-axis. From this kit protocol, you will just get the Y-value which is the % inhibition. To draw the graph, you will need the X value. You can get that by using standards (not included in the k...

We would recommend using at least 10 mg of tissue with the kit ab65354.

Collect using citrate or EDTA. Centrifuge at 1,000 x g for 10 min at 4°C. Remove plasma layer w/o disturbing the buffy layer and store at -80°C until ready for analysis. Remove the buffy layer from the red cell pellet. Resuspend erythrocytes in 5x volu...

Yes, you would need the 3 controls with each and every sample.
