Responses of <i>Xenopus</i> oocytes with co-expressed PxylOR1/PxylOrco or PxylOR4/PxylOrco to stimulation with pheromone compounds.

<p>(<b>A</b>) (Upper left) Inward current responses of PxylOR1/PxylOrco <i>Xenopus</i> oocytes in response to 10<sup>−4</sup> M of pheromone compounds and analogs. (Upper right) Response profile of PxylOR1/PxylOrco <i>Xenopus</i> oocytes. Error bars indicate SEM (<i>n = </i>6). (Lower left) PxylOR1/PxylOrco <i>Xenopus</i> oocytes stimulated with a range of <i>Z</i>11-16: Ald concentrations. (Lower right) Dose–response curve of PxylOR1/PxylOrco <i>Xenopus</i> oocytes to <i>Z</i>11-16:Ald. Responses are normalized by defining the maximal response as 100%. <i>Z</i>11-16: Ald EC50 = 2.39×10<sup>−5</sup> (n = 5). Error bar indicates SEM. (<b>B</b>) (Upper left) Inward current responses of PxylOR4/PxylOrco <i>Xenopus</i> oocytes in response to 10<sup>−4</sup> M of pheromone compounds and analogs. (Upper right) Response profile of PxylOR4/PxylOrco <i>Xenopus</i> oocytes. Error bars indicate SEM (<i>n = </i>7). (Lower left) PxylOR4/PxylOrco <i>Xenopus</i> oocytes stimulated with a range of pheromone Z9-14: Ac and analog Z9, E12-14: Ac concentrations, respectively. (Lower right) Dose–response curve of PxylOR4/PxylOrco <i>Xenopus</i> oocytes to Z9-14: Ac and Z9, E12-14: Ac. Responses are normalized by defining the maximal response as 100%. Z9-14: Ac EC50 = 2.43×10<sup>−7</sup> (<i>n = </i>7) and Z9, E12-14: Ac EC50 = 1.94×10<sup>−6</sup> (<i>n = </i>5). Error bar indicates SEM.</p>
