Abstract
The preparation and use of stable, ready-to-use substrate-chromogen solutions for the detection and quantification of peroxidase or pseudoperoxidase activity are described. The substrate-chromogen solution according to the present invention contains a buffer, preferably imidazole buffer, a polymer, a hydroperoxide substrate, a chromogenic organic electron donor and electron donor of the carbohydrate type as a stabilizer. The substrate-chromogen solution retains its full peroxidatic activity and develops a negligible color during storage.
