Fig. 5.
Micrographs of dissociated RB cells of the rat retina. A and C are Nomarski micrographs of two RB cells. B and D are the corresponding fluorescence micrographs showing immunoreactivity for the ρ subunits. Labeling is strongest in the axon terminals. Puncta of stronger immunofluorescence possibly represent clustering of the subunits at postsynaptic sites. Scale bar, 10 μm.
