title: The effect of cholecystokinin octapeptide on rat striatal 3H spiperone binding.
abstract: In the rat striatum sulphated CCK8 has no significant effect on equilibrium binding of 3H-spiperone but has a considerable, although transient, effect under non-equilibrium conditions. Under non-equilibrium conditions (during the association phase of ligand binding) and at high ligand concentrations (1 nM), CCK8 displaces specific binding and at low ligand concentrations (0.1 nM) CCK8 enhances specific binding. CCK8 has no effect on 3H-spiperone dissociation kinetics.
