Figure 2. Binding of monoclonal antibodies 2H3, 3H1, 3H5, 4E5 and 6B6 to live dengue-2 virus (untreated) and virus inactivated by HCHO (formaldehyde), INA or AMT. Viruses were coated onto wells of a Microtiter ELISA plate and reacted with antibodies in a standard ELISA assay using an HRP-conjugated anti-mouse IgG. Data shown are representative of two independent determinations.
