DNA methylation is one of the most well-studied epigenetic modifications, and has known roles in regulating gene expression and genomic stability. EpiCypher methyl DNA designer nucleosomes (MeDNA dNucs) are unmodified nucleosomes wrapped with unmethylated or hemi-methylated DNA, and are the optimal substrates for interrogating the function of DNA methylation on the binding activity of chromatin-associated proteins or inhibitors.
