Short summary
NMR studies can be of great help in understanding the molecular mechanisms of nucleosome functions. For solid-state NMR, nucleosomes need to be tightly packed together. We show that centrifugation of nucleosomes results in formation of gels with very high packing ratios yet without pronounced order in the packing and without formation of specific or stable inter-nucleosome contacts. This makes the approach suitable also for the study of proteins that bind weakly to the nucleosome.
