(A) Immunostaining of a cross-section of the bovine retina with an antibody against G_α11. (Nomarski optics; 8-μM frozen section.) The anatomical layers are as in Fig. 2. The arrows indicate blood vessels. (B) Immunoblotting of total bovine retinal proteins with the anti-G_α11 antibody. Sizes of molecular mass standards (×10⁻³) are shown adjacent to the lane. (C) Dissociated rod (Top) and cone (Bottom) cells stained with the same antibody. Again, only the rod outer segment (ROS), but apparently not the cone outer segment (COS), shows staining.
