Receptor Autoradiography

Receptor autoradiography involves the identification of receptors in tissue fragments or sections with the use of pharmacological binding methods. The earliest binding studies utilized high-specific-activity radiolabeled receptor li-gands and crude membrane preparations. The compound or ligand was bound selectively to a receptor site, and the membranes were then separated from the radiolabeled drug solution. Under appropriate conditions, the quantity of radiolabeled drug that bound to the membranes represented the quantity of receptors in the tissue. In order to apply binding methods to the study of receptors in a tissue as complex as the brain, modifications have been made in binding methods to allow for autoradiographic localization of specifically bound radiolabeled compounds.
