Other Information
Extinction Coefficient
Extinction coefficient of oxidized o-dianisidine may be used. It has been determined to be 1.13 X 104 M-1 cm-1. A fluorometric method of determining H2O2 in concentrations as low as 5 X 10-12 mole/ml has been described by Perschke and Broda (1961). Characteristics of Peroxidase from Horseradish Roots: 40,000 (Maehly 1955). Optimum pH: 7.0 (Maehly 1955). Composition: Seven isozymes have been described by Shannon et al. (1966);Kay et al. (1967); and Strickland et al. (1968). See also Delincée and Radola (1975) and Shih et al. (1971). All contain photohemin IX as prosthetic group. Neutral and amino sugars account for approximately 18% of the enzyme. Weinryb (1966) indicates that the "
