Correlative light electron and microscopy of cryostat sections can be used to identify rhodopsin enriched phagosomes in the retinal pigment epithelium (RPE) cell layer.
<p>The same region of RPE viewed by (A) fluorescence microscopy (FM) and (B) electron microscopy (EM), with an overlay of the two in (C). The boxed regions in (A-C) are shown at higher magnification in (D) highlighting regions that include FM rhodopsin staining (green) overlapping with phagosomes seen by EM. (E) Higher magnification of phagosomes (Ph) boxed in (D), surrounded by melanosomes (Me) and mitochondria (M). Scale bar = (A-C)– 10um (D)– 1um (E)– 250nm.</p
