A detailed description of a method for the determination of serum arginase activity is presented. Arginase activity is demonstrated by the decrease in arginine concentration in a reaction mixture, as determined by a modification of the method of Sakaguchi. The reaction is linear until inhibited by the increasing concentration of ornithine. The cellular distribution of arginase is reviewed to determine its role in diagnosis and in the evaluation of biologic systems.
