These particles are partially separable by sucrose density centrifugation into three peaks. Each population is stable and contains infectious particles. The particles of all three populations contain at least six polypeptide species that differ between particle populations only in quantity. All three populations contain a 50S RNA species, and the heaviest density peak also contains an additional species of 43S RNA. The difference between these results and previous studies with measles virions will be discussed., UL https://www.microbiologyresearch.org/content/journal/jgv/10.1099/0022-1317-45-2-441
