Catalase is a ubiquitous enzyme that destroys hydrogen peroxides formed during oxidative stress. Our OxiSelect™ Catalase Activity Assay Kits measure catalase activity in less than one hour from a variety of samples including blood, cells and tissues.
Direct spectrophotometric detection of catalase activity with ultraviolet light can cause interference from proteins and other biological components. The OxiSelect™ Catalase Activity Assay Kit (Colorimetric) utilizes visible light (520 nm), which reduces sample interference.
The OxiSelect™ Catalase Activity Assay Kit (Fluorometric) provides a 40-fold increase in sensitivity compared to our colorimetric assay.
