Additional file 2: Figure S1. of Alarm pheromone and kairomone detection via bitter taste receptors in the mouse Grueneberg ganglion

Grueneberg ganglion neurons express TAS2R131. (a) Immunohistochemistries on mice tongue tissue section (circumvallate papillae) with antibodies against TAS2R131 with and without its competing peptide to verify the staining selectivity. (b) Immunohistochemistries on mice GG sections with antibodies against TAS2R131 with and without its competing peptide to verify the staining selectivity. GG cells expressing GFP are visible in green due to the intrinsic expression of the GFP. White arrowheads correspond to enlarged views displayed in insets; nuclei are counterstained in blue with DAPI; scale bars are 20 μm. (TIF 4156 kb)
