Figure 2. Eph-A6 expression in Fd 110 macaque retina (foveal region) revealed by in situ hybridization. A: Antisense riboprobe strongly labeled the ganglion cell layer (GCL), particularly the innermost portion. B: Sense probe produced no specific labeling. Confocal gain and offset settings were the same in A and B. Abbreviations: inner nuclear layer (INL); inner plexiform layer (IPL); outer nuclear layer (ONL); outer plexiform layer (OPL).
