Abstract
A method for determining the level of infectious bursal disease virus IBDV neutralizing antibody in poultry comprising a labeled monoclonal antibody R63 having the IBDV neutralizing capability of the monoclonal antibody expressed by hybridoma cell line ATCC HB-9490. Monoclonal antibody R63 is specific to all known IBDV strains and serotypes and competes only with itself and other antibodies recognizing the same neutralizing epitope present in poultry sera. In a competition assay, the increase in unbound labeled monoclonal antibody is an indication of the level of IBDV neutralizing antibody present in poultry sera.
