Hola, In the descrption of the spectrophotometric method you have to have the relation betwen ud enzyme/ O.D., But the most appropiate is doing your own standar curve with definited amounts of pure protein ,or with known specific activity and compare with yours.Commercial horseradish perosidase have different units/mg depending if the valoration is made with pirogallol or ABTS. Make a graph with amounts of commercial peroxidase against O.D. and the yours Relationing the responses of both you can know how pure is your preparation. Buena suerte
