TABLE 2

Agonist binding affinities of the dopamine D2 receptor expressed alone or coexpressed with the dopamine D5 receptor

Competition binding experiments using [³H]raclopride were performed in membranes from cells stably transfected with the D2 receptor alone or cotransfected with the D5 receptor. The data represent the means ± S.E.M of six experiments, each performed in duplicate.
