    摘要: The present invention provides a method for recovering an essentially cell-associated expression product from a host cell comprising (a) culturing said host cell under conditions that allow expression of said expression product; (b) collecting said host cell in/on a filter unit; (c) disrupting said host cell in/on the filter unit; and (d) separating said expression product from said disrupted host cell. Said host cell is preferably a vertebrate cell, more preferably an avian cell, which is preferably cultured in suspension. Furthermore, the present invention provides for the use of a filter unit characterized in that said filter unit is (i) suitable to retain a host cell which expresses an expression product; and (ii) suitable for elution of said expression product from the filter unit after cell disruption in/on said filter unit for recovering said expression product from said host cell as well as for a system for recovering an expression product from a host cell comprising said filter unit. The present invention also provides an expression product obtainable by said method, said expression product being preferably a virus, specifically a poxvirus, in particular selected from the group consisting of fowlpoxvirus, vaccinia virus and, more preferably, modified vaccinia virus Ankara, MVA.

    摘要: The invention relates to vectors comprising two or more homologous nucleotide sequences and methods for generating them. The invention concerns substituting bases in the homologous nucleotide sequences with different bases that do not alter the encoded amino acid sequence. The invention allows for the reduction of intramolecular recombination between homologous nucleotide sequences, in particular in mammalian cells. The invention further relates to nucleotide sequences containing substituted bases.

    摘要: It is desirable to produce live vaccines, which are highly attenuated and which do only contain minimal or no animal-derived components. The production of highly attenuated live viruses can be better achieved when using specifically designed cell lines as producer substrate as opposed to using less defined primary cells. However, live viruses, thus produced comprise undesirable components from the cell lines and cell culture. The present invention relates to methods of production and purification of live enveloped viruses, which are suitable for vaccination.
