  • Monoclonal antibody immunoassay kit for avian reticuloendotheliosis virus
    Patent number: 5130232
    Abstract: The combination of monoclonal antibodies 11A25 and 11E32, which recognize two distinct antigenic sites on the 62-kd glycoprotein of reticuloendotheliosis virus (REV) in ELISA, enables an increase in the sensitivity of an ELISA assay for subtype 2 REV over what was heretofore possible. The combination of MAbs is useful for diagnosing REV antigen and antibody in poultry flocks and for detecting new strains and variants of the viral subtype.
