    摘要: Means and methods for producing mammalian viruses, the method comprising infecting a culture of immortalized human cells with a virus, incubating the culture infected with virus to propagate the virus under conditions that permit growth of the virus, and to form a virus-containing medium, and removing the virus-containing medium. The viruses can be harvested and be used for the production of vaccines. Advantages include that human cells of the present invention can be cultured under defined serum-free conditions and the cells show improved capability for propagating virus. Methods are provided for producing, in cultured human cells, influenza virus and vaccines derived thereof. This method eliminates the necessity of using whole chicken embryos for the production of Influenza vaccines. The method also provides for the continuous or batch-wise removal of culture media. As such, the present invention allows the large-scale continuous production of viruses to a high titer.

    摘要: The present invention provides methods of reducing the levels of a titratable selectable pressure required, the number of amplification cycles, and the time taken to generate protein expressing cell lines by altering the codons of the desired open-reading-frames. Through the use of codon adaptation for this purpose the methods of the invention consistently provide sufficient yields in faster time frames saving many weeks in cell line development activities. Furthermore the methods of the invention also generate cell lines with lower concentrations of selection and amplification agent than previously achievable. Accordingly lower levels of selection and amplification marker in the final cells lines are observed.

    摘要: The invention concerns a method of culturing, propagating and replicating in vitro viruses of the Togaviridae and Flaviviridae families which consists in: providing at least a fraction of LVP's obtained from serum or plasma of a patient infected with a least a virus of the Togaviridae and Flaviviridae families; contacting said fraction, for a predetermined time interval in an appropriate culture medium, with permissive cells having an endocytosis path relayed by at least one receptor of the lipoproteins and modulated inter alia by an activating agent selected among an unsaturated fatty acid or an unsaturated fatty acid derivative comprising 16 to 20 carbon atoms or their mixture. The invention also concerns the uses of viral particles and polypeptides obtained by said method.
