    • The present invention provides a method of manufacture of an anti-paratopic antibody comprising the steps of: (1) selecting from a pool of antibodies occurring in one species a prototypic set the members of which are effective in binding a specific antigen (or antigen epitope), and (2) utilizing one or more members of said prototypic set, or paratopic fragments thereof, as an immunogen in a host of a different species, or in an in vitro incubation system comprising cells derived from the same or a different species, to produce antibodies having a characteristic which is anti-paratopic with respect to said immunogen to produce a synthetic replicate of the specific antigen or epitope. Antigen (or antigen epitope), and monoclonal antibodies. vaccines and processes of immunization employing the product of the method of manufacture are also described.

    • The invention provides an alternative method of reversible aggregation and/or dissociation of polypeptides. Proteins or polypeptides according to the invention have an inherent aggregation capability, wherein the aggregation is an oligomerization of the polypeptide that is based on the presence and the strucuture of peptide repeats localized in a flexibly disordered domain of this polypeptide. The flexibly disordered domain comprising the peptide repeats preferrably is located in close proximity with the N-terminus of the protein amino acid sequence. Preferably, each of the peptide repeats has a sequence that comprises one to four identical octapeptides with the amino acid sequence: PHGGGWGQ. Preferred proteins are selected from the group comprising cellular prion proteins (PrPC) and engineered polypeptides or fusion proteins with a respective inherent reversible aggregation and dissociation capability. Because of the new mechanism of aggregation, the oligomerization reaction of the protein is reversible in a fluidic environment depending on the pH of this fluidic environment. Oligomerization occurs at a pH of 6.2 to 7.8, and the dissociation into monomers is reported to be at a pH range of 4.5 to 5.5. 1
    • 本发明提供了多肽的可逆聚集和/或解离的替代方法。 根据本发明的蛋白质或多肽具有固有的聚集能力,其中聚集是多肽的寡聚化,其基于定位于该多肽的柔性无序结构域中的肽重复序列的存在和结构。 优选地,包含肽重复序列的柔性无序结构域位于蛋白质氨基酸序列的N-末端附近。 优选地,每个肽重复序列具有包含1-4个与氨基酸序列PHGGGWGQ相同的八肽的序列。 优选的蛋白质选自包含细胞朊蛋白(PrP))和具有相应固有的可逆聚集和解离能力的工程改造的多肽或融合蛋白。 由于聚合的新机制,蛋白质的低聚反应在流体环境中是可逆的,这取决于该流体环境的pH。 低聚发生在6.2至7.8的pH下,据报导单体的解离在4.5至5.5的pH范围内。
