[Human recombinant antibodies to Ebola virus: preparation and characteristics]

Human recombinant antibodies against a purified Ebola virus (EV) lysate were selected from a combinatorial library of scFv-antibodies using the phage display technique. Nine unique antibodies were identified after sequencing the Vh- and Vl-genes encoding the selected antibodies. Solid-phase enzyme immunoassay (EIA) indicated that these antibodies were able to bind both inactivated and native EV. Immunoblotting showed that 6 antibodies identified nucleoprotein (NP), one antibody did VP24 and another antibody did VP40. One of the selected antibodies reacted with two EP proteins: VP24 and VP40. Solid-phase EIA demonstrated cross-reactivity with Marburg virus (MAR) and defined VP24 MAR as a target protein for the antibody.
