A B-cell line producing a human monoclonal antibody (HuMAb) against a recombinant 40-kDa outer membrane protein (OMP) of Porphyromonas gingivalis was constructed by in vivo immunization of a severe combined immunodeficiency C.B.-17/Icr mouse, which had been injected with human peripheral blood lymphocytes, with recombinant 40-kDa OMP and subsequent Epstein-Barr virus immortalization of B cells isolated from the spleen of the mouse. This HuMAb inhibited coaggregation between P. gingivalis vesicles and Actinomyces naeslundii cells.
