For such analysis, homogeneous nucleosome stretches of precise length must be used, which can be purified through CsCl ultracentrifugation [113] or sucrose gradient centrifugation [114,115] of MNase-digested chromatin. Reinberg and co-workers have recently developed this idea, using a chromatin ...
Over the next 20 years, many studies exploited salt-dependent chromatin aggregation for the purposes of isolation and enrichment. Marushige and Bonner confirmed that after digestion with DNase II, rat liver chromatin could be separated into two fractions based on the aggregation of the released chrom...
2. Nucleosome position and the sequence specificity in MNase digestion After the MNase digestion, there are many bands of yeast chromatin corresponding to that of naked DNA, although some bands of naked DNA do not appear on chromatin due to the protection by nuoleosomo. The correspondence of ...
1a). In this study, the optimal MNase digestion (4U) generated a DNA ladder with the majority of DNA as mono- and di-nucleosomes (Supplementary Fig. 1b). Compared to input samples at G1 phase, nucleosomes at nascent chromatin were less well organized based on analysis of nucleosome ...
and the crosslinked protein–DNA complexes. In order to analyze protein-binding sequences, the extracted genomic DNA must be sheared into smaller, workable pieces. DNA fragmentation is usually achieved either mechanically by sonication or ...
C. Analysis of Assembled Chromatin by Partial Digestion The efficiency of the chromatin assembly reaction can be evaluated by partial micrococcal nuclease (MNase) digestion (see Figure 2) (Diagenode, Catalog No. C06070001). Partial digestion with the micrococcal nuclease (MNase) will reveal periodic...

Spheroplasted cells were treated with 0.01171875 U (low MNase) or 0.1875 U (high MNase) micrococcal nuclease (Sigma-Aldrich, N5386-200UN) in digestion buffer (1 M sorbitol, 50 mM NaCl, 10 mM Tris pH 7.4, 5 mM MgCl2, 0.075% NP-40, 1 mM β-mercaptoethanol, 0.5...
Mouse, rats and few human diseases are also used as good models to study age related changes in chromatin. Analysis of the 30 nm fibres andMicrococcalnuclease (MNase) digestion of the nuclei have indicated that there is irregular positioning of the nucleosomes in the chromatin of aged fibroblast...
48 h later, cells were treated with MNase for 0 or 15 min. After MNase digestion, DNA was purified and 5 μg of DNA were analyzed by 1.2% agarose gel electrophoresis. D. M33 does not colocalize with compact chromatin in NIH3T3 cells. NIH3T3 cells were transfected with GFP-M33. Images...
