Fig 3. In situ hybridization of Chrna7 digoxigenin labeled anti-sense RNA probe in rat CV taste papillae sections.

Shows images of rat CV papilla sections labelled with Alexa Fluor® 488 (FITC), DAPI, the merged images of FITC and DAPI, and the DIC image. The anti-sense (AS) Chrna7 riboprobe labeled a subset of rat CV taste bud cells (AS). No significant fluorescence was observed when the sense (S) probe was used. Bar = 10 μm.
