Figure 13. Glutamine profiles across the Survivor-light damage (LD)-Decimation gradient. Visualization: Quantitative gray-scale images of glutamine signals displayed as intensity. Up arrows, remnant retina-choroid interface; downward arrow is the small high glutamine seal region. The bottom panel is 0.579 mm wide and shows isolated glutamine gradients in retina, retinal pigment epithelium (RPE), choroid, seal, emigrant and decimated zones. All decimated zones show large numbers of holes (see Methods). Sample metadata: SD Rat, age at LX 60 d, animal #P240–2L-24, left eye, 24 h LX, harvested at 240 days pLX, bloc code 6685, slide code 3518.
