Experimental procedure and mixture of agonists. (A) 300-μm thick coronal acute slice through the OE of a transgenic Olfr73-GFP mouse. Scale bar, 100 μm (B) Identification of single GFP-labeled Olfr73 neurons for whole-cell patch clamp measurements. Scale bar, 5 μm (C) Representative patch clamp trace comparing the odor-induced receptor currents elicited by a 1 s application of MIEG (500 μM) or vanillin (100 μM), respectively. (D) Mixtures of strong agonists (vanillin, eugenol) (100/10 μM) with MIEG (500 μM) to evaluate MIEGs' antagonistic potential. Mixtures were applied for 1 s every 30 s and the amplitudes were compared to control measurements (vanillin and eugenol applied separately).
