Immunolocalization of NBC-1 in the eyes. (a) Peroxidase-antiperoxidase staining of the human eye in the absence, Ag(-), and presence, Ag(+), of the antigen peptide. NBC-1 staining is brown. Co, cornea; Le, lens; Tm, trabecular meshwork; st, corneal stroma; en, corneal endothelium; cp, lens capsule; ep, lens epithelium; fb, lens fiber cells; sc, Schlemm’s canal. (b and c) Confocal laser microscopic image (confocal) and Nomarski-differential interference microscopic image (diff) of human (b) and rat (c) eyes. Red shows the localization of NBC-1 and green shows nuclei. Cb, ciliary body; pg, pigmented ciliary epithelium.
