  • Patent number: 5087693
    Abstract: Stable heterohybridomas which secrete monoclonal antibodies to bovine herpesvirus-1 (BHV-1) are obtained by fusing primed bovine lymphocytes with an immortal cell line, selecting for secretial hybrids, and sequentially re-fusing such hybrids with fresh bovine lymphocytes. Three such heterohybridomas which secrete neutralizing antibody to BHV-1 have been obtained in this manner and have been deposited in the ATCC as Accession Nos. HB9907, HB9908, and HB9909. The neutralizing antibodies are useful in immunological research, pathological diagnosis, and therapeutic disease control. Specifically, they have utility as serologic control regents in assays, and as primary reagents in anti-species, anti-isotype, and anti-idiotypic antibody production.
    Type: Grant
    Filed: April 23, 1991
    Date of Patent: February 11, 1992
    Assignee: The United States of America as represented by the Secretary of Agriculture
