  • Title: The localization of spectrin on the inner surface of human red blood cell membranes by ferritin-conjugated antibodies.
    Author: Nicolson GL, Marchesi VT, Singer SJ.
    Journal: J Cell Biol; 1971 Oct; 51(1):265-72. PubMed ID: 5000071.
    Abstract:
    Spectrin, a major protein constituent of mammalian red blood cell membrane preparations, has been localized on the inner surface of human red blood cell membranes by techniques that utilized specific ferritin-conjugated antibodies and fixation of membranes shortly after hemolysis so as to allow penetration of the ferritin-antibody labels. The labeling of spectrin was shown to be specific by the following criteria. (a) Nonhomologous ferritin-conjugated antibodies did not specifically bind to either membrane surface. (b) Blocking the membrane-bound spectrin with excess unconjugated antispectrin antibodies prevented ferritin-antibody labeling. (c) Removal of spectrin by treating the membrane preparation with a low ionic strength buffer containing ethylenediaminetetraacetate and beta-mercaptoethanol prevented labeling by specific ferritin-conjugated antibodies.
