title: Development of a radioimmunoassay for aprindine.
abstract: We have developed a radioimmunoassay for aprindine, a new antiarrhythmic drug used in the treatment of ventricular disorders. The antibodies were produced by immunization of New-zealand rabbits with aprindine coupled to human serum albumin. Their biochemical characteristics have been determined. Tritiated aprindine was used as radioactive competitor. The cross-reactivity with several metabolites of aprindine was studied too. Finally, the results obtained by RIA in plasma and tissues of dogs were compared to those obtained by gas-chromatography.
