title: Dopa and dopamine in glusulase: possible artifact in studies on catecholamine metabolism.
abstract: Relatively high concentrations of dopa and dopamnine were found in Glusulase, an enzyme preparation widely used in studies on catecholamine metabolism. This contamination may be a source of error in some studies, particularly in those measuring the endogenous concentrations of these catechols and their metabolic products.
