CATALASE (EC 1.11.1.6), is an ubiquitous antioxidant enzyme that catalyzes the decomposition of hydrogen peroxide (H2O2) to water and oxygen. By preventing excessive H2O2 build up, catalase allows important cellular processes which produce H2O2 as a byproduct to occur safely. Deficiency in catalase activity has been associated with grey hair and peroxisomal disorder acatalasia. Simple, direct and high-throughput assays for catalase activity find wide applications. This improved assay directly measures catalase degradation of H2O2 using a redox dye. The change in color intensity at 570nm or fluorescence intensity (lambda ex/em = 530/585nm) is directly proportional to the catalase activity in the sample.
