  • Patent number: 6264954
    Abstract: Purified and isolated nucleic acid from specific strains of Haemophilus influenzae is provided which encodes at least a portion of the D15 outer membrane protein of Haemophilus. The nucleic acid is used to produce peptides, polypeptides and proteins free of contaminant associated with Haemophilus for purposes of diagnosis and medical treatment. Furthermore, the nucleic acid may be used in the diagnosis of Haemophilus infection. Antisera obtained following immunization with the nucleic acid D15 outer membrane protein or peptides also may be used for the purpose of diagnosis and medical treatment.

  • Patent number: 5985288
    Abstract: The gene for outer membrane protein P1 of Haemophilus influenzae b is expressed in E. coli. Methods for expression and demonstration of the immunogenicity of recombinant P1 and portions thereof are disclosed, along with an improved method for the purification of P1. The nucleotide sequence of the P1 gene and the derived amino acid sequence of the P1 protein of Haemophilus influenzae type b are disclosed and the methods used to determine the same. Also disclosed are the methods used to clone and express the P1 gene as well as the purification protocol for the P1 gene products (recombinant P1 and P1 fusion proteins). Fourteen peptides are synthesized corresponding to specific sequences of the mature P1 protein. The use of the P1 protein as n immunogens for immunization against the disease caused by Haemophilus influenzae type b and the use of the protein as a carrier for conjugation with an oligosaccharide derived from Haemophilus to generate a potentially efficacious vaccine against the disease, are described.

  • Patent number: 5972349
    Abstract: Polyribosylribitol phosphate oligosaccharides are produced in a multistep process. The compound of the formula: ##STR1## wherein R.sub.1 is a first protecting group and R.sub.2 is a second protecting group, is coupled to a solid polyethylene glycol monomethyl ether (PEG) support. Following removal of the first protecting group, the resulting compound is coupled with a repeating unit for chain elongation of the formula: ##STR2## The protecting group is removed from the phosphorus atom and the steps of removing the first protecting group, coupling with the repeating unit is repeated until the desired number of repeating units in the oligomer has been terminated. The oligomer then is terminated with a chain terminating molecule of the formula: ##STR3## wherein m is an integer and R.sub.3 is a third protecting group.

  • Patent number: 5679352
    Abstract: Synthetic peptides have an amino acid sequence corresponding to at least one antigenic determinant of at least one protein, usually a structural protein, particularly the P1, P2 and P6 protein, of Haemophilus influenzae (Hi), particularly type b, and are used as is, in chimeric T-B form, in lipidated form, linked to a carrier molecule, particularly a synthetic PRP molecule and/or polymerized to form molecular aggregates, in vaccines against Hi.
