agilent: DNA methylation
home services platforms agilent: DNA methylation


Epigenetic studies using differential methylation hybridisation (DMH) provide insight into DNA methylation on a global scale. As much of the methylation occurs in CpG Island regions, these types of arrays are often used for these studies, although CGH and promoter arrays can also be used depending on the nature of the experimental design.

There are two methodologies used to examine DMH. The first involves methylation sensitive restriction enzymes. The second involves an immunoprecipitation with a methylation-specific antibody (MeDIP). Both methods are currently acceptable. We do require that the restriction digest or the immunoprecipitation and subsequent amplification are performed prior to sending the samples. Both methods require a total of 2 ug of DNA. Please refer to the ChIP-on-chip service for more information about the caveats of ChIP-on-Chip if you are planning on following the MeDIP method .
