Catalase is a crucial enzyme that catalyzes the decomposition of hydrogen peroxide (H₂O₂) into water and oxygen, playing a vital role in protecting cells from oxidative damage.

Accurate measurement of catalase activity is essential for understanding its involvement in various physiological and pathological processes, including oxidative stress, aging, and diseases such as cancer and neurodegeneration.

Catalase activity assays utilize various detection methods, such as colorimetric and spectrophotometric techniques, to quantify enzyme activity in diverse biological samples, including tissues, serum, and cell lysates.
