Abstract

Importance of the problem

The complete study of a virus disease often reaches a stalemate because of failure to isolate the virus itself in a purified form. Methods in current use, such as ultracentrifugation, precipitation, fractionation, and spectroscopic analysis, have in some cases proved successful in virus purification work. Frequently these techniques have not proved satisfactory, particularly with phloem-type viruses which are not mechanically transmitted. This investigation was undertaken to determine the possibility of isolating these and other viruses by electrochromatography.
