Abstract
Procedures for the extraction and purification of the yeast histone oc tamer 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 regio n of histone H2B, permitting resolution of the histone octamer from hi gh-salt extracts of nuclei or chromatin to near homogeneity. The histo ne octamer purified in this way was fully active in reconstitution of nucleosomes.
