A procedure has beer, developed for purifying intact virus's isolate particles evoking yellow spot mosaic disease in sunflower. Purification of pathogen in 0,1 M sodium phosphate buffer, pH 8.0 containing 0.05 M Na-3SO-3 and 0.2% 2-mercaptoethanol is used. After first clarification extract was exposed to two cycles of high-speed centrifugation and fractionated in linear 10-40% (wt vol-1) sucrose density gradient. Virus was recovered from appropriate fractions after dialysis against 0.01 M Na-2SO-3.
