Immunohistochemical localization of tight junction proteins in cryosections of the retina. Anti-claudin immunoreactivity is clearly present in the NFL (a,c), ZO-1 is present also at the outer limiting membrane. In (c) axons are labeled for the neurofilament- associated protein 3A-10. Nuclear stains clearly show the presence of cell nuclei in NFL. OLM, outer limiting membrane. Scale bars are 20 μm in (a,b), 10 μm in (c).
