OxiSelect™ Superoxide Dismutase Activity Assay Kit

• Measure superoxide dismutase activity using a standard microplate reader
• Suitable for use with plasma, serum, cells or tissues
• Superoxide dismutase standard included for absolute quantitation

Superoxide dismutase (SOD), which catalyzes the dismutation of the superoxide anion into hydrogen peroxide and molecular oxygen, is one of the most important antioxidant enzymes. SOD enzymes are classified into three groups: cytosolic CuZn-SOD, mitochondrial Mn-SOD, and extracellular Ec-SOD. Our OxiSelect™ Superoxide Dismutase Activity Assay uses a xanthine/xanthine oxidase (XOD) system to generate superoxide anions and a chromagen to produce a water-soluble formazan dye upon reduction by superoxide anions. The superoxide dismutase activity is determined as the inhibition or reduction of chromagen.
