Expression of EGFP-PDE6β1-313 in transgenic X. laevis rods photoreceptors.
A. left - EGFP fluorescence in living photoreceptor cells expressing EGFP-PDE6β1-313, center - DIC image, right - EGFP-fluorescence/DIC overlay. Bar - 10 µm. B. Co-localization of EGFP-PDE6β1-313 (green) with the rod outer segment marker Wheat Germ Agglutinin (red) in cryosections of transgenic retina. Cryosections were counterstained with TO-PRO3 nuclear stain (blue). Bar - 10 µm. C. Isotonic (I), hypotonic (H) extracts of transgenic EGFP-PDE6β1-313 retinas were analyzed by immunoblotting with anti-GFP B-2 monoclonal antibody.
