  • Publication number: 20070036828
    Abstract: This application relates to improved Group B Streptococcus (“GBS”) saccharide-based vaccines comprising combinations of GBS polysaccharides with polypeptide antigens, and vice versa, such that the polypeptide and the saccharide each contribute to the immunological response in a recipient. The combination is particularly advantageous where the saccharide and polypeptide are from different GBS serotypes. The combined antigens may be present as a simple combination where separate saccharide and polypeptide antigens are administered together, or they may be present as a conjugated combination, where the saccharide and polypeptide antigens are covalently linked to each other.

  • Patent number: 7167819
    Abstract: The present invention provides a fast and efficient method for determining the three-dimensional conformation of a protein. The steps of the method of the invention include: 1) formation of physical distance constraints, e.g., forming intramolecular chemical crosslinks of known size between residues of a protein; 2) enriching the number of the molecules that have intramolecular chemical crosslinks in the reaction pool, e.g., using size separation to remove proteins with intermolecular bonds; 3) exposing the enriched reaction pool to a protease that cuts the protein at specific sites to produce peptide fragments; 4) measuring the size of the peptide fragments to determine linkage sites with a certain spatial relationship in the protein; and 5)interpreting the data produced to determine spatial geometry and protein structure based on the deduced spatial relationship of the linkage sites.

  • Patent number: 7166446
    Abstract: Compositions and methods for expression of heterologous mammalian proteins and their secretion in the biologically active mature form using a yeast host cell as the expression system are provided. Compositions of the invention are nucleotide sequences encoding a signal peptide sequence for a yeast secreted protein, an optional leader peptide sequence for a yeast secreted protein, a native propeptide leader sequence for a mature protein of interest, and a sequence for the mature protein of interest, all operably linked to a yeast promoter. Each of these elements is associated with a processing site recognized in vivo by a yeast proteolytic enzyme. Any or all of these processing sites may be a preferred processing site that has been modified or synthetically derived for more efficient cleavage in vivo. The compositions are useful in methods for expression of heterologous mammalian proteins and their secretion in the biologically active mature form.

  • Publication number: 20060292556
    Abstract: A family of cDNA sequences derived from hepatitis C virus (HCV) are provided. These sequences encode antigens which react immunologically with antibodies present in individuals with non-A non-B hepatitis (NANBV), but which are absent from individuals infected with hepatitis A virus, or hepatitis B virus, and also are absent in control individuals. The HCV cDNA sequences lack substantial homology to the sequences of hepatitis delta virus (HDV) and HBV. A comparison of the sequences of amino acids encoded in the HCV cDNA with the sequences of Flaviviruses indicated that HCV may be related to the Flaviviruses. The HCV cDNA sequences and the polypeptides encoded therein are useful as reagents for the detection and therapy of HCV. The reagents provided in the invention are also useful for the isolation of NANBV agent(s), for the propagation of these agents in tissue culture, and for the screening of antiviral agents for HCV.
