Immunoelectron microscopic photograph of the apoptotic photoreceptors. Apoptotic photoreceptor nuclei shown in Figure 6 ▶ are seen as irregularly shaped nuclei in the sections fixed in 1% paraformaldehyde and embedded in LR white. AIF is positive in the cytoplasm and nucleus of apoptotic photoreceptors. The dense staining of AIF on the nucleus is remarkable. Normal photoreceptors are negative in AIF staining. Original magnification, ×10,000.
