Fig 3. Screening new ligands of Hex-Hex Mix receptors.

Dose response curves of OR1A1, OR2J3, OR2W1, OR5K1, OR5P3 and OR10A6 for indicated odorants: Methyl ß -naphthyl ketone, l-carvone, methyl isoeugenol, phenylethyl acetate. The HEK293 cells transfected with each OR were stimulated by 0.1 to 300 or 1000 μM of these odorants and luciferase assay was performed. Fold increases are shown as means and SE (n = 3–5). *p < 0.05, **p < 0.01, ***p < 0.001, Fisher's LSD post-test.
