Abstract
Superoxide dismutase activity is determined by measuring hydrogen peroxide produced by using superoxide anion as a substrate and acting superoxide dismutase thereon in the presence of an electron carrier. When maleimide or a derivative thereof, and if necessary, a carbonyl compound, and if further necessary bromine ions and/or citric acid or a salt thereof are added to the electron carrier, the sensitivity and the linearity of calibration curves are further improved.
