Abstract
Glycyl beta-naphthylamine and alanyl beta-naphthylamine are suitable chromogenic substrates for aminopeptidase. They are hydrolyzed rapidly by human serum, duodenal juice and bile and also by extracts of several human organs, mainly kidney. Naphthol liberated is determined quantitatively by azo-coupling. The histochemical localization of amino[long dash]peptidase activity is feasible by this technique.Keywords
