Figure 3. REST regulated neuronal genes are activated in post-mitotic fiber cells. A: Hematoxylin and eosin stained mouse lens. B: Mouse mAb βIII-tubulin. C: Rabbit mAb anti-βIII-tubulin. D: Chicken anti-βIII-tubulin. E: Anti-Synaptophysin 1. F: Mouse mAb Synaptotagmin 1. G: Rabbit anti-Synapsin 1. H: DAPI as in G. I: No primary antibody control (lo), DAPI. J: Synapsin 1 in retinal neuronal layers (autofluorescence is seen in photoreceptor layer). K: mAb βIII-tubulin. L: Synaptotagmin 1 in peripheral fiber cells.
