Responses of ItypOR25 in oocytes. (A) Representative current traces of oocytes upon successive exposures to 100 μM stimuli. Each compound was applied at the time indicated by the arrowheads for 20 s. Upper and lower traces include different sets of test stimuli. (B) Response profile of ItypOR25 to the full odor panel. Values were normalized based on the average response to the primary ligand of ItypOR25 (n ≥ 4). (C) Dose-dependent responses of oocytes expressing ItypOR25 to active ligands. Values were normalized based on the average response of ItypOR25 to the most active compound at 100 μM (n ≥ 4 for each ligand). Error bars indicate the SE.
