Abstract:

Monoclonal antibody specific for Fusobacterium nucleatum was reacted with untreated and formalin fixed F. nucleatum cells by an enzyme-linked immunosorbent assay ELISA and by indirect immunofluorescence. Treatment of bacterial cells with formalin destroyed the antigenic determinant responsible for reactivity with this monoclonal antibody in both assays. Formalin fixation had no effect on hemagglutination activity HA of F. nucleatum cells or reactivity with polyvalent rabbit antiserum by double diffusion in agar. Scanning electron microscopy demonstrated that formalin fixation did not affect binding of F. nucleatum cells to microtiter plates. When developing monoclonal antibodies that will be used as diagnostic reagents, the antigen form utilized for immunization should be identical to the antigen form which will eventually be used in the diagnostic assay.
