Abstract: The invention relates to antibodies, and antigen binding fragments thereof, that potently neutralize infection of ZIKV. The invention also relates to antigenic sites to which the antibodies and antigen binding fragments bind, as well as to nucleic acids that encode and immortalized B cells that produce such antibodies and antibody fragments. In addition, the invention relates to the use of the antibodies and antibody fragments of the invention in screening methods as well as in the diagnosis, prophylaxis and treatment of ZIKV infection.
Abstract: The present invention provides monoclonal antibodies, or antigen-binding fragments thereof, that bind to ZIKV glycoproteins, pharmaceutical compositions comprising the antibodies and methods of use. The antibodies of the invention are useful for inhibiting or neutralizing ZIKV activity, thus providing a means of treating or preventing ZIKV infection in humans. In some embodiments, the invention provides for use of one or more antibodies that bind to the ZIKV for preventing viral attachment and/or entry into host cells. The antibodies of the invention may be used prophylactically or therapeutically and may be used alone or in combination with one or more other anti-viral agents or vaccines.

Abstract: The disclosure concerns a method and kits for measurement of an analyte in a microparticle-based analyte-specific binding assay. In the assay, the microparticles are coated with the first partner of a binding pair, mixing the coated microparticles and at least two analyte-specific binding agents, each conjugated to the second partner of the binding pair, and a sample suspected of containing the analyte. The second partner of the binding pair is bound to each of the analyte-specific binding agents via a linker comprising from 12 to 30 ethylene glycol units (PEG 12 to 30), thereby binding the analyte via the conjugated analyte-specific binding agents to the coated microparticles. The method also entails separating the microparticles having the analyte bound via the binding pair and the analyte-specific binding agent from the mixture and measuring the analyte bound to the microparticles.
