Ultrastructural immunohistochemical localization of polyclonal IgG, C3, and amyloid P component on the congo red-negative amyloid-like fibrils of fibrillary glomerulopathy

Renal biopsies from seven patients with Congo red-negative amyloid-like fibrillary glomerulopathy (FGP) were examined by protein A gold immuno-electron microscopy. Ultrastructurally, the fibrils in all cases exhibited positive immunostaining for IgG, both Ig light chains, C3, and amyloid P component...
