  • Patent number: 5503992
    Abstract: Murine monoclonal antibodies directed against a novel outer membrane protein (OMP) of Haemophilus influenzae have been isolated and characterized. The gene encoding of the outer membrane protein has also been isolated and characterized. Portions of the DNA sequence of the 15 kD OMP gene are useful as probes to diagnose the presence of Haemophilus influenzae in samples. These DNA's also make available polypeptide sequences of immunoreactive epitopes encoded within the gene, thus permitting the production of polypeptides which are useful as standards or reagents in diagnostic tests and/or as components of vaccines. Monoclonal antibodies directed against epitopes of the 15 kD OMP are also useful for diagnostic tests and as therapeutic agents for passive immunization.
