  • Immunogenic reagents from west nile virus
    Patent number: 8475808
    Abstract: Recombinant production of immunogenic West Nile Virus (WNV) proteins is described. These proteins, heterodimers comprising the proteins, fusions thereof, polynucleotides encoding the proteins, and combinations thereof, as well as antibodies produced therefrom, can be used in immunogenic compositions for preventing, treating and diagnosing WNV infection. Also described are highly sensitive ELISA and strip immunoassay methods for detecting the presence of WNV in biological samples.
    Type: Grant
    Filed: May 21, 2004
    Date of Patent: July 2, 2013
    Assignee: Novartis Vaccines and Diagnostics, Inc.
    Inventors: William Andrews, David Chien, Qui-Lim Choo, Stephen Coates, Doris Coit, Charles Harrington, Susan Hilt, Michael Houghton, Angelica Medina-Selby, Sergio Pichuantes, Yiu-Lian Fong
  • Methods and reagents for diagnosing hantavirus infection
    Publication number: 20110053140
    Abstract: Novel methods and immunodiagnostic test kits for the detection of hantavirus infection are disclosed. The methods and kits employ combinations of recombinant N and/or G1 antigens from at least six different hantavirus serotypes, including Hantann (HTNV), Puumala (PUUV), Seoul (SEOV), Dobrava (DOBV), Sin Nombre (SNV) and Andes (ANDV). Additional hantavirus antigens from these and other hantavirus types may also be present. The methods provide for highly accurate results and allow the detection of infection so that treatment can be administered and death avoided.
