The benzodiazepine receptors of bovine brain membranes have been identified by the specific binding of radiolabeled [3H]diazepam. Pretreatment of membranes with N-ethylmaleimide causes a dose- and time-dependent decrease of 45 to 60% in the number of binding sites. No decrease occurs when membranes are pretreated with N-ethylmaleimide before administration, or in the presence, of diazepam. Binding of [3H]diazepam to the remaining sites occurs with the same characteristics as binding to the untreated receptor population.

Abstract

The benzodiazepine receptors of bovine brain membranes have been identified by the specific binding of radiolabeled [3H]diazepam. Pretreatment of membranes with N-ethylmaleimide causes a dose- and time-dependent decrease of 45 to 60% in the number of binding sites. No decrease occurs when membranes are pretreated with N-ethylmaleimide before administration, or in the presence, of diazepam. Binding of [3H]diazepam to the remaining sites occurs with the same characteristics as binding to the untreated receptor population.
