title: Characterization of neurotensin receptors.
abstract: This unit describes procedures for performing competition binding assays with neurotensin receptor subtypes 1 and 2 (NTS1 and NTS2). Binding assays using cloned receptors, brain membranes, and primary cultured mesencephalic neurons are presented. NTS1 binding assays employing either radiolabeled neurotensin or SR 48692 (a nonpeptide neurotensin antagonist) as radioligands are described. These procedures may be used to screen selective ligands at neurotensin receptor subtypes.
