Nucleosome Preparation Kit
easily isolate mononucleosomes and oligonucleosomes
- More physiologically relevant substrates than synthetic peptides
- Useful for the analysis of histone post-translational modifications, enzyme kinetics or inhibitor screening studies
- Easily adjust the levels of mononucleosomes or oligonucleosomes isolated by adjusting digestion times

Easily prepare mononucleosomes or oligonucleosomes from your samples
The ability to regulate the amount of mononucleosomes or oligonucleosomes isolated with the Nucleosome Preparation Kit based on digestion time with the Enzymatic Shearing Cocktail is shown in Figure 1. A comparison of isolated nucleosomes with purified nucleosome DNA in Figure 2 illustrates the gel shift observed in the molecular weight of the nucleosome sample, thereby confirming the nucleosome is intact with DNA wrapped around the histone proteins.
