SOD Activity Assay Kit
Easy and fast quantitative determination of SOD enzyme activity.
The SOD Activity Assay Kit provides a fast and reliable method for the quantitative determination of Superoxide Dismutase (SOD) enzyme activity.
In this assay, superoxide ions are generated from the xanthine–xanthine oxidase system. These superoxide ions convert the tetrazolium salt WST-1 into a colored formazan product, measured at 450 nm. Addition of SOD reduces superoxide levels, decreasing formazan formation. SOD activity is calculated as the percent inhibition of WST-1 formazan generation.
With a streamlined protocol, ready-to-use reagents, and high reproducibility, this kit is ideal for oxidative stress research, antioxidant screening, and enzymatic activity assays.

FAQs
Q: How is SOD activity measured?
A: As the percent inhibition of WST-1 formazan formation at 450 nm.
Q: What homogenization ratio should be used for tissue samples?
A: A typical starting point is 1:10 (w/v), e.g. 10 mg tissue in 100 µL of ice-cold buffer.
Q: Can smaller tissue amounts be used for SOD activity measurement?
A: Yes, lower amounts can be used, but sample preparation and dilution conditions must be optimized to obtain signals within the assay’s linear range.
