Figure 3 Expression of ORs and OMP. R-001, R-006, and R-046 correspond to the nasal mucosae of the ethmoturbinal II, frontoturbinal, and anterior nasal chamber, respectively. R-008 originated from the olfactory bulb, and both R-214 and R-215 were obtained from the external skin. The average expressions of intact ORs exhibiting non-zero expression were as follows: R-001, 0.370±0.503; R-006, 2.286±3.054; R-046, 0.045±0.068; R-008, 0.146±0.236; R-214, 0.106±0.061; R-215, 0.078±0.038.
