    Abstract:
    Hybrid cells producing monoclonal antibodies against antigens of Neisseria gonorrhoeae were obtained by the polyethylene glycol-mediated fusion of mouse myeloma cells and lymphocytes from mice immunized with gonococcal protein I or outer membrane proteins. From four fusions, 16 phenotypically stable, independently cloned hybrid cell lines were selected for continued study. Each of the cell lines produced a characteristically different monoclonal antibody which reacted in immunoprecipitation assays with a unique antigenic determinant on protein I of the outer membrane complex of the bacteria. In antibody binding, immunofluorescence, and coagglutination assays these antibodies each reacted with a restricted group of N. gonorrhoeae strains. None of the monoclonal antibodies reacted with 17 other different species of Neisseria or with Branhamella catarrhalis. When tested on 34 N. gonorrhoeae reference serotyping strains, the monoclonal antibodies demonstrated serological relationships between the strains which paralleled those observed with conventional polyvalent antisera. These antibodies now provide standardized reagents for the rapid and precise serological characterization of many strains of N. gonorrhoeae.
