Monoclonal antibodies directed against the envelope glycoprotein and the NV3 non-structural viral protein of yellow fever (YF) were tested by the indirect fluorescent antibody technique against a variety of YF virus strains and heterologous flaviviruses. Monoclonal antibodies directed against the envelope glycoprotein exhibited YF strain-specificity, YF type-specificity, broad group cross-reactivity, or limited subgroup reactivity (YF + Banzi or YF + Koutango + Zika + Usutu + Uganda S). Monoclonal antibodies directed against NV3 reacted either with YF + Koutango or with YF + Banzi. These findings generally correlated with the results of biological tests reported previously. Monoclonal antibodies that were type-specific to YF will be useful for the rapid specific identification of YF virus isolates and are available from the Centers for Disease Control on request.
