摘要:
A high molecular weight polysaccharide intracellular adhesin (SAE) antigen having the general structure of poly-1,6,β-2-amidoglucopyranoside, which is variable substituted with N-acetyl and O-succinyl substituents is described. Also, a method is given for isolating this antigen from Staphylococcus aureus. The SAE can be used in a vaccine, either alone, conjugated to an immunogenic protein, and/or with an immunogenic adjuvant.
摘要:
Human Papillomavirus virus like particles (VLPs) have been constructed so that they contain a modified L2 protein. The L2 protein has been minimized and is fused to a second protein or peptide. The fused protein is incorporated into the VLP and the VLP can deliver the protein to a cell. The modified VLPs can be used to increase the breadth of immune response in vaccine preparations or to deliver other proteins of interest.
摘要:
Recombinant expression vectors encoding the L1 and L2 proteins of papillomavirus, methods of making and using the recombinant proteins and purified virus-like particles comprised of the recombinant proteins are provided.
摘要:
The present invention features polypeptides comprising an amino acid sequence structurally related to SEQ ID NO: 1 and uses of such polypeptides. SEQ ID NO: 1 is a truncated derivative of a full-length S. epidermidis polypeptide. The full-length naturally occurring polypeptide is referred to herein as full-length ORF1319e. A His-tagged derivative of SEQ ID NO: 1 was found to produce a protective immune response against S. epidermidis.

摘要:
A process for purifying papillomavirus virus-like particles (VLPs) includes the step of passing a partially purified VLP-containing solution through a hydroxyapatite chromatography column. The VLPs are then eluted using a buffer containing phosphate anion. The advantages of this method include the recovery of a high yield of intact VLPs.
