  • Immunogenic peptides of foot-and-mouth disease viruses
    Patent number: 6984387
    Abstract: The present invention relates to FMDC vaccine based on peptides having a sequence of at least 8 amino acids, which corresponds to a partial sequence of the non-structural protein region of FMDV, which was selected by immunoreactivity with FMDV-specific antibodies or by immunoreactivity with FMDV-specific T lymphocytes, and to their production and their use.

  • Method for the analytical separation of viruses
    Patent number: 5723031
    Abstract: The method permits the non-destructive analytical detection and/or the quantification of viruses or viral particles (analytes) in a liquid sample matrix containing organic or inorganic minor constituents, in particular protein moieties and/or nucleotides and/or other viruses. To this end the viruses or the viral particles are separated from the protein moieties and/or nucleotides in the sample matrix using capillary electrophoresis and at the same time the electropherogram associated therewith is recorded. The fractions assigned to the analytes can then be identified as virus peaks in the electropherogram by spectroscopic interpretation with the aid of characteristic maxima. For better identification, a reference sample of a known virus or of a known viral particle can be added to the sample matrix.
