  • Title: Detection of IgG bound at the erythrocyte membrane by means of an immunohistochemical gold-silver technique.
    Author: Zimmermann N, Halbhuber KJ, Feuerstein H, Linss W.

    Abstract:
    The binding of IgG at the erythrocyte membrane during aging plays an important role in the elimination process of the cells by the reticulohistiocytic system. By means of an indirect protein A gold- and protein A gold-silver-method bound IgG was detected immunocytochemically on physiologically aged, pronase and neuraminidase treated red blood cells (RBC). At the light and electron microscopic level an increased binding of IgG at "old" as well as enzymatic treated cells in comparison to "young" and normal RBC was noted. The silver enhancement of gold particles visualized the immunostaining and permitted the semiquantitative analysis of the RBC by a scanning microdensitometer.
