Dengue virus-specific and flavivirus group determinants identified with monoclonal antibodies by indirect immunofluorescence.

Monoclonal antibodies produced against the four dengue virus serotypes identified four categories of reactions by immunofluorescence: flavivirus group reactive, dengue complex specific, dengue subcomplex specific (DEN-1, DEN-3), and dengue serotype specific. This is the first time that monospecific antibodies have been available for all of these unique antigenic determinants. Hybridoma cell lines producing dengue type-specific antibodies have been deposited in the Hybridoma Cell Bank of the American Type Culture Collection (Rockville, MD) for general distribution.
