Figure 2. Immunolabeling for αB-crystallin in AMD. αB-crystallin is expressed in retinal pigment epithelium cells in eyes with early and advanced age-related macular degeneration. αB-crystallin immunolabeling is seen in cells of the retinal pigment epithelium (RPE) layer, frequently near drusen in eyes with early dry age-related macular degeneration (AMD). αB-crystallin is more widespread throughout the RPE of eyes with more advanced dry AMD and is frequently seen in RPE cells lying above drusen. The arrow is pointing at the retinal pigment epithelium. Original magnification of the image was 20× [4].
