DNAメチル化についての理解は、転写の制御、ゲノムインプリンティング、胚発生、および発癌の研究に不可欠です。 Diagenodeは、シーケンシングまたはqPCRによるバイサルファイト変換と免疫沈降（IP）を提案しており、これらはDNAメチル化研究の2つの主要なアプローチです。

Capture methylated DNA via methyl-binding domain (MBD) of human MeCP2 protein
Bisulfite modification of DNA is the most commonly used, "gold standard" method for DNA methylation studies providing single nucleotide resolution. This technology is based on the chemical conversion of unmethylated cytosine to uracil. Methylated cytosines are protected from this conversion allowing to determine DNA methylation at the singe nucleotide level. Various analyses can be performed on the altered sequence to retrieve this information: bisulfite sequencing, pyrosequencing, methylation-specific PCR, high resolution melting curve analysis, microarray-based approaches, and next-generation sequencing.
Treatment of DNA with bisulfite converts cytosine residues to uracil, but leaves 5-methylcytosine residues unaffected (see Figures).
The MBD technology used in our MethylCap Kit is based on the very high affinity of a H6-GST-MBD fusion protein for methylated DNA. This protein consists of the methyl binding domain (MBD) of human MeCP2, as a C-terminal fusion with Glutathione-S-transferase (GST) containing an N-terminal His6-tag. The H6-GST-MBD fusion protein can be used to specifically isolate DNA containing methylated CpGs.
Diagenode’s MethylCap Kit enables high enrichment of double-stranded DNA and a differential fractionation in function of the methylated CpG density. Fractionation reduces the complexity of samples and makes subsequent next generation sequencing easier. Prior to the MethylCap assay, DNA is first extracted and sheared using the Bioruptor® Sonicator.
The Methylated DNA IP (MeDIP) is based on the affinity purification of methylated DNA using an antibody directed against 5-methylcytosine (5-mC) or 5-hydroxymethylcytosine (5-hmC) in the case of hMeDIP.
In brief, Methyl DNA IP is performed as follows: Genomic DNA from cultured cells or tissues is prepared, sheared, and then denatured. Then, immunoselection and immunoprecipitation can take place using the antibody directed against 5 methylcytosine and antibody binding beads. After isolation and purification is performed, the IP’d methylated DNA is ready for any subsequent analysis as qPCR, amplification, hybridization on microarrays or next generation sequencing.
