Catalase from murine liver 

Protein determined by biuret

Catalase activates the decomposition of hydrogen peroxide, a reactive oxygen species, into water and oxygen. It functions as a natural antioxidant, protecting cells against oxidative damage to proteins, lipids and nucleic acids. Catalase has also been used to study the role reactive oxygen species play in gene expression and apoptosis.

Freezing of solutions is not recommended.

One unit will decompose 1.0 μmole of H₂O₂ per min at pH 7.0 at 25 °C, while the H₂O₂ conc. falls from 10.3 to 9.2 mM, measured by the rate of decrease of A₂₄₀.
