Sigma-Aldrich Superoxide Dismutase, SOD, Activity Assay Kit. sufficient for 500 colorimetric tests. 1 kit

Superoxide dismutase (SOD) is part of a family of metal ion-containing enzymes (SODs) that are found in most organisms, from bacteria to mammals. SODs catalyze the dismutation of superoxide (generated by aerobic respiration) to molecular oxygen and peroxide. Superoxide dismutase form the front line of defence against reactive oxygen species (ROS)-mediated injury and harbor anti-inflammatory activities. The Superoxide Dismutase (SOD) Activity Assay Kit provides a simple and sensitive procedure for measuring SOD enzymatic activity in various sample types. SOD activity is determined by measuring the decrease in superoxide anions (generated by the enzyme xanthine oxidase [XO]). Since superoxide anions interact with the provided WST dye, yielding color at 450 nm, the decrease in the color signal is proportional to SOD inhibition activity. The kit allows the determination of SOD activity in percent inhibition, or in units of activity using the provided SOD Enzyme as a standard. The provided SOD Enzyme can also be used to screen for SOD inhibitors.
The kit’s lowest limit of detection is 0.3 SOD units/mL. This kit can be used to measure SOD activity in biological samples such as serum, plasma and erythrocytes, tissue homogenates and cell lysates.
Components This kit contains sufficient reagents for 500 colorimetric tests.
