QUANTITATIVE MAPPING OF CHROMATIN ASSOCIATED PROTEINS

摘要

The present invention relates to DNA-barcoded recombinant nucleosomes and polynucleosomes that have been engineered for use as spike-in controls for the quantitative mapping of chromatin associated proteins using Chromatin ImmunoPrecipitation (ChIP) assays, tethered enzyme-based mapping assays, and other chromatin mapping assays. The invention further relates to methods of using the engineered DNA-barcoded recombinant nucleosomes in ChIP assays, tethered enzyme-based mapping assays, and other chromatin mapping assays.
