One unit decomposes 1,0 µmole of hydrogen peroxide per minute at pH 7,0, 25 °C.


  • Sterile aqueous solution


Stoke's radius: 5,12 nm - catalase does not require any activators, but is inhibited by 3-amino-1-H-1,2,4 triazole, cyanide, azide, hydroxylamine, cyanogen bromide, 2-mercaptoethanol, dithiothreitol, dianisidine, and nitrate. Catalase is also inhibited by ascorbate and ascorbate with Cu²⁺. Incubation of catalase with ascorbate or ascorbate/Cu²⁺ results in degradation of the catalase molecule.


Activates the decomposition of hydrogen peroxide, natural antioxidant used to study roles of reactive oxygen species in gene expression and apoptosis. Catalase catalyses the decomposition of hydrogen peroxide into water and oxygen.


Catalase is often used as an antioxidant in cell culture media. It has been used to study the role of ROSs in gene expression and apoptosis, mainly in cancer researches. Catalase is used to eliminate H₂O₂ from enzymatic oxidation reactions.
