The Methylated DNA Immunoprecipitation is based on the affinity purification of methylated and hydroxymethylated DNA using, respectively, an antibody directed against 5-methylcytosine (5-mC) in the case of MeDIP or 5-hydroxymethylcytosine (5-hmC) in the case of hMeDIP.
How it works
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.
