|Enzyme Activity:||Other Activities|
|Synonyms:||catalase; hydrogen-peroxide:hydrogen-peroxide oxidoreductase|
|Concentration:||Supplied at ~ 18,000 U/mL|
|Expression:||Purified from Aspergillus niger|
|Specificity:||Decomposition of hydrogen peroxide into water and oxygen.|
|Specific Activity:||~ 4,960 U/mg protein (using A240 method) at pH 7.0 and 25oC|
|Unit Definition:||One Unit of catalase activity will decompose one µmole of H2O2 per minute at pH 7.0 and 25oC, while the H2O2 concentration falls from 10.3 mM to 9.2 mM. The rate of disappearance of H2O2 is followed by observing the rate of decrease in the absorbance at 240 nm (A240).|
|Application examples:||For use in research.|
