title: Size determination of binding polymers for [3H]imipramine and [3H]paroxetine in human platelet membranes.
abstract: Imipramine and paroxetine both inhibit the transport of serotonin in serotonergic neurons and in platelets; furthermore specific high affinity binding sites for [3H]imipramine and [3H]paroxetine are located in these two cell types, probably on the serotonin transport mechanism. However, previous studies indicated that the binding site for [3H]imipramine was different from the binding site for [3H]paroxetine. We now report that the polymers on which the two binding sites are located have different molecular weights.
