Summary Forty-two hybridomas secreting IgM antibody against dengue virus were derived from spleen cells of dengue 2 infected mice. Antibody from 27 of these recognised the E protein of this virus. Of the 22 antibodies which neutralised dengue 2, only two cross-reacted with other flaviviruses. These 22 antibodies recognised three discrete domains on dengue virions. Competitive binding studies with IgG monoclonal antibodies suggested that two of the three domains were recognised by both IgG and IgM antibodies and that there were two additional domains which may be recognised exclusively by either IgG or IgM antibodies. IgM antibodies reacting with domains recognised by IgG antibodies that enhanced infection of susceptible cells by dengue 2, had no enhancing properties. None of the IgM antibodies activated the serum complement system after reacting with dengue 2 virions. |
