| 20120135029 | METHOD FOR THE PURIFICATION OF PROTEIN COMPLEXES - The present invention provides an improved method for the purification of a mixture of complexes comprising a stress protein complexed to a peptide or peptide fragment from a source mixture, typically a cell lysate. The method of the invention provides for protein complexes to be purified using ion exchange chromatography based methods, wherein a modified buffer solution is used which results in the purified stress protein complexes being more immunogenic than protein complexes obtained using conventional methodology. The purified complexes can be used to produce improved vaccine preparations which elicit enhanced immune responses in the subjects to whom the vaccine compositions are administered. | 05-31-2012 |
| 20110206725 | METHOD FOR PURIFYING PROTEIN COMPLEXES - The present invention provides a method for the purification of complexes comprising a stress protein complexed to a peptide or peptide fragment, from a source mixture, typically a cell lysate. The improved method of the invention provides for protein complexes to be purified using ion exchange based methods, without the need to use chemicals such as chaotropes and ampholytes. The purified complexes can be used as the immunogenic determinant in vaccine compositions for the treatment or prevention of infectious diseases or cancerous conditions. | 08-25-2011 |
| 20090186025 | Fusion Protein Comprising an Fc Receptor Binding Polypeptide and an Antigenic Polypeptide for Mediating an Immune Response - The present invention provides a fusion protein comprising an Fc receptor binding polypeptide and an antigenic polypeptide. The fusion peptide may further comprise a linker sequence or hinge portion which joins the Fc receptor biding polypeptide and the antigenic polypeptide. The Fc receptor binding polypeptide typically comprises the CH2 constant domain of a human IgG immunoglobulin. The antigenic polypeptide can be any polypeptide which induces an immune response. Administration of the fusion protein to a subject results in a cytotoxic T lymphocyte response being induced against the antigenic polypeptide provided within the fusion protein. The invention further extends to methods for the treatment of a disease condition in a subject using the fusion proteins of the invention. | 07-23-2009 |
