Figure 2. Cellular localization of the Mas receptor protein in mouse the retina. Cell type specificity of the Mas receptor expression in the adult mouse retina was detected with coimmunostaining of the anti-Mas receptor antibody with specific retinal cellular markers for (A-C) cone photoreceptors (PNA-biotin), (D-F) rod photoreceptors (rod-arrestin), and (G-I) ganglion cells (Brn3a). The nuclei were counterstained with 4',6-diamidino-2-phenylindole (DAPI). ONL=outer nuclear layer; RGC=retinal ganglion cell layer. Representative images at 400X magnification. Scale bar=50 μm.
