PUPO, Maritza et al. Dengue virus antibodies dependent amplification in Cuban strains by using monoclonal antibodies. Rev Cubana Med Trop [online]. 2004, vol.56, n.3, pp. 197-202. ISSN 1561-3054.

The different behaviors of antidengue monoclonal antibodies serotype 2 (H3/6, 4G3) and antiprotein recombinant from the dengue virus sheath were described when they faced diverse strains from the serotypes 2 and 4 of this virus (D2 New Guinea C, A15 Cuban strain and A15 propagated 53 times in culture of Beagley dog kidney and D4 H-22412 prototype strain) in an immunoamplification assay dependent of antibodies. Themonoclonal antibodies have prove to be an efficient tool to explain that the neutralizatrion and increase of viral multiplicity may be carried out as separate biological functions. Only the H3/6 monoclonal antibdoy was capable of producing the amplification assay dependent phenomenon against the A15 strain with a significant rise in the viral multiplication. The 4G3 and 4B6 monoclonal antibodies were not capable of immunoamplifying the viral multiplication of the studied strains.
