Purification of Plant Viruses SpringerLink

2020-3-6  Purification methods vary with different viruses, and there are no universal methods of virus purification. Procedures that are effective for one virus may not work with the other. Stable viruses that reach high concentration in their propagation hosts are easy to purify compared to viruses that are less stable and occur in low concentration in

The Purification of Plant Viruses ScienceDirect

This chapter presents an outline on the purification of plant viruses and discusses the methods of purification. Appropriate steps toward purification are described in detail both for those viruses that have yet to be purified and for those that have already been obtained as relatively monodisperse suspensions but for which there is interest in securing the highest degree of purity possible.

Purification of viruses by electrophoresis in sucrose

Abstract. Zone electrophoresis (ZE) in concentration gradients of sucrose proved to be a powerful technique in the purification of viruses although it is seldomly used as a single step for the separation of the infective agent from extraneous matter but usually as a final procedure. No difficulties were experienced in the purification of plant
