Histone Purification from Saccharomyces cerevisiae.

Résumé

The nucleosome structure consists of a histone octamer made by a tetramer of H3-H4 histones and two dimers of H2A-H2B. Nucleosomes undergo extensive posttranslational modifications that regulate nucleosome interactions, position, and stability.We describe a protocol allowing the robust purification of histones from the yeast Saccharomyces cerevisiae. This method appears to be suitable to quantitatively analyze specific posttranslational histone modifications.
