[Distribution of diphenoloxidases (DPOx) in various tissues of various animal species (author's transl)].

An oxidative activity has been demonstrated in different tissues of various animals species (man, rabbit, hen, rat, mouse) measuring it by means of adrenaline, by starch gel electrophoresis and acrylamide gel electrofocusing, followed by incubation of these gel with DOPA. Kidney, liver and erythrocytes of rabbit, rat, mouse and hen, human erythrocytes and platelets display a high oxidative activity. This activity, which is not completely inhibited by KCN, is found in one band on starch gel electrophoresis and in two distinct bands on electrofocusing in the case of platelets and erythrocytes of man, rabbit and rat. The starch gel electrophoretic migration and the electrofocusing pattern are tissue and species dependent.
