Abstract
The present invention relates to methods for purification of Vaccinia viruses (VV) and/or Vaccinia virus (VV) particles, which can lead to highly pure and stable virus preparations of predominantly biologically active viruses. The invention encompasses purifying a virus preparation in a sterilized way with high efficiency and desirable yield in terms of purity, biological activity and stability, aspects advantageous for industrial production.
Claims28
A method for the purification of biologically active Vaccinia virus comprising:
- i) binding the Vaccinia virus to a solid-phase hydrophobic interaction chromatograpy (HIC) matrix;
- and
- ii) eluting the biologically active virus.
