PSF protein is present in normal retina and associated with retinal vessels. Immunohistochemical evaluation of normal rat retina was performed on 3-μm-thick paraffin-embedded serial sections using anti-PSF Ab (a), nonimmune IgG (b), and anti–von Willebrand factor Ab’s (c). Immunoreactivity of PSF and von Willebrand factor (vWF) exhibited similar distribution (arrowheads). There was no immunoreactivity observed with nonimmune IgG.
