Abstract：
:The experiments reported in this paper address the hypothesis that [3H]leucine enkephalin labels both mu and delta receptors. As reported by other workers, this peptide dissociates from rat brain membranes in a biphasic manner. This is consistent with a two site binding model which hypothesizes that the peptide labels both opioid mu and delta receptors from which it dissociates at different rates. To test this hypothesis, we determined the dissociation of bound ligand from rat brain membranes incubated to equilibrium with [3H]leucine enkephalin in the absence and presence of 100 nM morphine. The data were not significantly different. We conclude that the biphasic off-kinetics of [3H]leucine enkephalin is not evidence for a two-site binding model.
