Patent number: 6444211Abstract: Pertactin (formerly 69 kDa protein) is recovered in stable biologically pure form having no detectable adenylate cyclase activity from fermentation broth from the fermentation of Bordetella pertussis as well as from the cells. The broth is processed to selectively remove pertussis toxin (PT) and filamentous haemagglutinin (FHA), the pertactin is precipitated by ammonium sulphate and the precipitate is dissolved in buffer at pH 6.0 to 8.5, the solution then is passed through hydroxyapatite and ion-exchange chromatograph columns before final ultrafiltration. Cells are extracted with urea and the extract ultrafiltered and diafiltered. The pertactin is precipitated from the extract and the precipitate processed as above. In a variation, the broth is contacted with ammonium sulphate to precipitate pertactin, PT and FHA, the precipitate is dissolved and the PT and FHA selectively removed, before the solution is passed to the chromatograph columns.Type: GrantFiled: June 8, 1999Date of Patent: September 3, 2002Assignee: Connaught Laboratories, Inc.Inventors: Gail Jackson, Raafat Fahim, Larry Tan, Pele Chong, John Vose, Michel Klein

Patent number: 5985288Abstract: 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.Type: GrantFiled: June 7, 1995Date of Patent: November 16, 1999Assignee: Connaught Laboratories LimitedInventors: Robert S. Munson, Jr., Susan Grass, Pele Chong, Yan-Ping Yang, Raafat Fahim, Dwo Yan Charles Sia, Patrick McVerry, Michel Klein

Patent number: 5916562Abstract: The nucleotide sequence of the P2 gene and the derived amino acid sequence of the P2 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 P2 gene as well as the purification protocol for the gene and protein. Also disclosed is the synthesis of peptides corresponding to the N-terminal and C-terminal ends of the P2 protein. Also disclosed is the use of the P2 protein as a protective agent for 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. Also disclosed is the use of P2 peptide-conjugates as immunising agents.Type: GrantFiled: September 20, 1993Date of Patent: June 29, 1999Assignees: Connaught Laboratories Limited, Washington UniversityInventors: Robert S.
