D2 dopamine receptors in rat striatum are homogeneous as revealed by ligand-binding studies.
D2 dopamine receptors in rat striatum have been analysed using the binding of [3H]domperidone. Competition experiments were performed with classical dopamine antagonists and antagonists reported by other workers to discriminate D2 dopamine receptor sub-classes. In all cases competition data conformed to a single binding site interaction so that there is no evidence for heterogeneity of the D2 dopamine receptor.
