title: Nonisotopic receptor-binding assay for benzodiazepine receptors utilizing a fluorophore labeled ligand.
abstract: A nonisotopic receptor-binding assay method provides a new approach for the study of receptor-ligand interactions and a possible receptor assay for benzodiazepine drugs. The proposed method is based upon the use of fluorescence-labeled drugs and a chromatographic system which accepts samples without deproteinization. The effectiveness of the technique is illustrated in a study of benzodiazepine receptor-drug-binding interactions.
