  • Title: Sodium azide inhibition of complement-mediated functions.
    Author: Shaw DR, Shaw MW, Hickman SE, Lamon EW, Griffin FM.
    Journal: Immunology; 1980 Jan; 39(1):53-6. PubMed ID: 7380463.
    Abstract:
    Moderate concentrations of sodium azide (0.1-0.2%) significantly inhibited guinea-pig and human complement-mediated lysis of both IgM- and IgG-sensitized sheep erythrocytes. The reduction in cytolysis was not attributable to non-specific ionic effects, to inactivation of native complement components by azide, or to irreversible interactions of azide with sensitized erythrocytes. Mouse complement-dependent opsonization of sensitized erythrocytes, as judged by macrophage complement receptor-mediated attachment and phagocytosis of the erythrocytes, was comparably inhibited by sodium azide, suggesting that azide acted within the sequence of the first four components of the classical complement pathway.
