In situ analysis of the expression of the two classes of receptors in the goldfish olfactory epithelium. Hybridization was carried out at high stringency on coronal sections of the epithelium by using fragmented antisense digoxigenin-labeled RNA probes. (A and C) Low-power and high-power views of GFA25. (B and D) Low-power and high-power views of GFB14. [Scale bar for A and B is shown in B (200 μm), and that for C and D is shown in D (50 μm).]
