title: Temperature-sensitive conformational changes in membrane-bound and solubilized [3H]imipramine binding sites.
abstract: [3H]Imipramine binding sites are located on serotonergic nerve terminals and on blood platelets. Previous studies on our laboratories have indicated temperature-sensitive conformational changes in [3H]imipramine binding sites in hippocampal and cerebral cortex membranes. We now report that similar changes are observed in both membrane-bound and digitonin-solubilized [3H]imipramine binding sites of human blood platelets. This may indicate integrity of the solubilized binding site.
