Figure 5. Immunohistochemical localization of albumin in the posterior retina and sclera

Immunohistochemical localization of albumin in IRBP^+/+ (A,B) and IRBP^-/- (C,D) mouse retina. Mouse albumin was used as a competitor in B and D. Note that immunospecific staining was restricted to the sclera (asterisk) and retinal blood vessels (arrows). No immunospecific staining of the interphotoreceptor matrix was detected. Horizontal arrows identify the position of the external limiting membrane.
