Dopa oxidase activity and ceruloplasmin in the sera of hamsters with melanoma.

Two simple spectrophotometric assays have been employed for the measurement of dopa oxidase activity and ceruloplasmin polyphenol oxidase activity in the sera from normal hamsters and hamsters bearing melanotic melanoma. Both activities were found to be augmented in tumor animals, the dopa oxidase activity much more prominently. The levels of the enzymes tested increased proportionally to the tumor mass.
