Purification of plant viruses and virus coat proteins by

High performance liquid chromatography (HPLC) gel filtration has been successfully applied in the purification of elongated and isometric plant viruses. Two different approaches have been tested. In one approach, semi-purified virus particles were dissociated with lithium chloride and the released c

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.
