Purification of free polyhedrosis virus infecting Galleria mellonella L.
Free Galleria mellonella nuclear polyhedrosis virus was purified 4000--4500 times by Tween-80 treatment and repeated sucrose density gradient centrifugation, based on the ratio of infectivity to protein content as compared to the starting virus-containing suspension.
