  • Title: Monoclonal antibodies associated with sodium channel block nerve impulse and stain nodes of Ranvier.

    Journal: Brain Res; 1984 Sep 17; 310(1):168-73. PubMed ID: 6089966.
    Abstract:
    Monoclonal antibodies were generated against native eel electroplax sodium channels in their natural membrane. These antibodies block nerve conduction in rat central (optic) and peripheral (sciatic) nerve. The antibody binding to eel electroplax membrane fragments and to rat brain synaptosomes can be modulated by neurotoxins. Thus it implies that active sites of the sodium channels are immunogenic in their natural membrane. Unlike the antibodies described in the past, our antibodies recognize antigenic determinants which are associated with the physiological activity of the channel and have been conserved through evolution.
