title: Purification of poliovirus 14 S subunits by sucrose gradient ultracentrifugation and high-performance size-exclusion chromatography.
abstract: Purification of 14 S subunits from extracts of poliovirus-infected HeLa cells was achieved by a combination of sucrose gradient ultracentrifugation and high-performance size-exclusion chromatography. The particles were free of admixtures of other subviral particles, of nonstructural viral proteins, and of host cell proteins. The purified material retained the physical and antigenic properties of native 14 S subunits fully, as well as their ability to assemble to empty capsids in vitro.
