RESUMO
Procedures for the extraction and purification of the yeast histone octamer are described. Either mechanical disruption, yielding chromatin fragments, or spheroplast formation with subsequent nuclear isolation was employed. A hexahistidine tag was inserted in the N-terminal region of histone H2B, permitting resolution of the histone octamer from high-salt extracts of nuclei or chromatin to near homogeneity. The histone octamer purified in this way was fully active in reconstitution of nucleosomes.
