摘要： The present invention provides for a novel method for purification of EGFR family proteins obtained from cultures of insect cells. The process comprises subsequent steps of a) diafiltration and exchange of culture medium with buffer, b) immobilized metal affinity chromatography (IMAC), c) size exclusion chromatography (SEC), and d) anion exchange chromatography (AIE). The method also provides for an immunogenic variant of HER-2 protein for which the purification process has been especially adapted, as well as means for the preparation of the variant.

摘要： Disclosed are novel methods for combating diseases characterized by deposition of amyloid. The methods generally rely on immunization against amyloidogenic proteins (proteins contributing to formation of amyloid) such as beta amyloid (Aβ). Immunization is preferably effected by administration of analogues of autologous amyloidogenic polypeptides, said analogues being capable of inducing antibody production against the autologous amyloidogenic polypeptides. Especially preferred as an immunogen is autologous Aβ which has been modified by introduction of one single or a few foreign, immunodominant and promiscuous T-cell epitopes while substantially preserving the majority of Aβ's B-cell epitopes. Also disclosed are nucleic acid vaccination against amyloidogenic polypeptides and vaccination using live vaccines as well as methods and means useful for the vaccination. Such methods and means include methods for identification of useful immunogenic analogues of the amyloidogenic proteins, methods for the preparation of analogues and pharmaceutical formulations, as well as nucleic acid fragments, vectors, transformed cells, polypeptides and pharmaceutical formulations.

摘要： A method is disclosed for inducing cell-mediated immunity against cellular antigens. More specifically, the invention provides for a method for inducing cytotoxic T-lymphocyte immunity against weak antigens, notably self-proteins. The method entails that antigen presenting cells are induced to present at least one CTL epitope of the weak antigen and at the same time presenting at least one foreign T-helper lymphocyte epitope. In a preferred embodiment, the antigen is a cancer specific antigen, e.g. PSM, Her2, or FGF8b. The method can be exercised by using traditional polypeptide vaccination, but also by using live attenuated vaccines or nucleic acid vaccination. The invention furthermore provides immunogenic analogues of PSM, Her2 and FGF8b, as well as nucleic acid molecules encoding these analogues. Also vectors and transformed cells are disclosed. The invention also provides for a method for identification of immunogenic analogues of weak or non-immunogenic antigens.

摘要： One aspect is a method for improved preparation of molecular imprinted polymer (MIP) particles, where initial compositions comprising insoluble MIP particles are enriched for those MIP particles that bind a particular target molecule, thus excluding non-binding and weakly binding particles from the final composition. Enrichment is typically accomplished via use of chromatographic methods capable of separating particulate material or by means of agglutination. Another aspect is preparation of improved insoluble MIPs by use of extended micronization of raw MIP particles with a view to expose a large number of binding sites per mass unit of MIP particles. In preferred embodiments the two aspects are combined. The resulting improved MIPs may be used for diagnostic, analytical and therapeutic purposes, notably as orally administered drugs which can bind substances such as cholesterol and bile acids and bile acid salts in the gastrointestinal tract.
