Fig. 7. (A) Graph showing the percentages of gold particles, representing myosin VIIa labeling, distributed on the melanosome membrane versus those unassociated with the melanosomes but present elsewhere in the RPE cytoplasm. (B) Comparison of the labeling in the regions apical and basal to the adherens junctions of the RPE (relative amount of label on the melanosome membrane is also indicated). Data were obtained from sections with negligible background labeling (there was no labeling on the adjacent ROSs or extracellular space) and negligible labeling on simultaneously-processed, negative control sections.
