Figure 7. Localization of PKC δ-like immunoreactivity in vertical sections of the rat retina.

Figure 7

A, microphotograph of the photoreceptor layer taken with differential interference contrast optics. ROS, rod outer segments; IS, inner segments; ONL, outer nuclear layer. B, confocal image showing immunofluorescence detection of PKC δ. Immunoreactivity is seen at the transition from rod inner to outer segments. Four putative cone outer segments (arrows) are strongly labelled. C, confocal image of cone opsin immunoreactivity. The four structures from B (arrows) are unequivocally identified as cone outer segments. Scale bar, 20 μm.
