The Catalase (CAT) Activity Assay Kit is widely used in research and diagnostics to measure catalase enzyme activity in biological samples. It is particularly valuable in studies related to oxidative stress, as catalase plays a critical role in breaking down hydrogen peroxide into water and oxygen, thus protecting cells from oxidative damage. This kit is commonly applied in fields such as biochemistry, molecular biology, and toxicology to assess the antioxidant capacity of tissues, cells, or enzymes. It is also utilized in agricultural research to evaluate plant stress responses and in pharmaceutical studies to test the efficacy of antioxidant drugs. The UV spectrophotometry method, which monitors the decrease in hydrogen peroxide absorbance at 240 nm, ensures accurate and reliable quantification of catalase activity, making it a preferred choice for high-throughput screening and experimental analysis.
