[The use of monoclonal antibodies in studying the causative agents of viral hemorrhagic fevers]. / Ispol'zovanie monoclonal'nykh antitel v issledovanii vozbuditelei virusnykh gemorragicheskikh likhoradok.

The most promising trends of using monoclonal antibodies (Mabs) in virology research of the viral hemorrhagic-fevers' agents are related with studying viral antigen structure and with developing diagnostic preparations for indicating and identifying infectious agents of the mentioned pathologies. The methodological specificity of obtaining the Mabs to viral hemorrhagic-fevers' agents as well as data on its practical use are discussed.

[Production and study of hybridomas, producing monoclonal antibodies to the structural glycoprotein of Marburg virus]. / Poluchenie i izuchenie gibridom, produtsiruiushchikh monoklonal'nye antitela k strukturnomu glikoproteinu virusa Marburg.

Hybridomas producing monoclonal antibodies (MAb) to Marburg virus glycoprotein were prepared by splicing of mouse myeloma cells (NSO and X.63-Ag6.653 strains) and splenocytes of immunized BALB/c mice. Cultural and MAb-producing properties of hybridomas were studied. The production of MAb during serial passages 15-30 was confirmed. MAb titers in culture fluids were 1:4096-1:8152, in immune ascitic fluids of BALB/c mice 1:409,600-1:638,400. The possibility of using MAbs as a component of ELISA test system was demonstrated. The sensitivity of ELISA-MAb method for Marburg virus was 1 x 10(3) PFU/mu.
