Medium isotope effect in [3H]diazepam binding to benzodiazepine receptors of synaptic membranes.
Replacement of H2O by D2O resulted in significantly higher amount of [3H]diazepam specifically bound to synaptic membranes. The isotope effect arises from increased number of binding sites in D2O and is associated with a stronger solvation of membrane receptors by heavy water.
