RESUMO

Vesicular stomatitis virus was disrupted by a combination of freezing and thawing, osmotic shock, and sonic treatment. Subviral components were separated by isopycnic centrifugation. The low-density, lipid-rich fractions were pooled and shown to contain primarily viral glycoprotein. Further purification of this material resulted in the isolation of a preparation of vesicles which contained only the G protein and the same phospholipids as in the intact virions and exhibited spikelike structures similar to those on intact vesicular stomatitis virions. We conclude that we have isolated fragments of native vesicular stomatitis virus envelopes.
