Response of various olfactory receptors to odorants. a Odorant response pattern of four different hOR-Ks (hOR2AG1-K, hOR1A2-K, hOR3A1-K, and hOR1G1-K) to various odorants. The hOR-Ks are the fusion proteins of human olfactory receptor and potassium channel. b Bar graph of the fluorescence intensity measured from the image scanning data.
