OxiSelect™ Catalase Activity Assay Kit (Colorimetric)

• Quantify catalase activity in about 60 minutes
• Suitable for use with whole blood, plasma, serum, cell lysates or tissue homogenates
• Catalase standard included for absolute quantitation

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. Each kit provides sufficient reagents to perform up to 100 assays in a 96-well microtiter plate, or 50 assays in microcentrifuge tubes. This includes blanks, catalase standards and unknown samples. 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.
