In the initial screening of commercially available anti-Gα<sub>i-3</sub> antibodies, two were identified and one was selected for further investigations based on efficacy with adenosine—the most potent agonist in our previous research. After optimizing experimental conditions with rat and postmortem human brain membranes, the stimulatory effects of various agonists were evaluated. Some agonists, including nociceptin, exhibited sufficient stimulatory effects for further pharmacological characterization. Nociceptin increased [<sup>35</sup>S]GTPγS binding to Gα<sub>i-3</sub> in a concentration-dependent manner, response that was insensitive to naloxone but potently inhibited using (±)-J-113397. The method described in this study provides a valuable strategy for determining the intrinsic efficacy of ligands at various GPCRs.
