Density gradient centrigugation in sucrose solutions has proved useful in experiments to separate the sugar beet yellows virus from normal constituents of leaf homo-genates. After dialysis at pH 6.8 in a combined veronal-phosphate buffer following centrifugation the virus had lost practically none of its serological activity and only a little of its infectivity. Density gradient centrifugation as a means of preventing compact sediments is especially useful in attempts to isolate thread-like particles.
