Methylated-CpG Island Recovery Assay

Methods Mol Biol. 2011:791:125-33. doi: 10.1007/978-1-61779-316-5_10.

Abstract

Alterations in DNA methylation patterns are implicated in playing a major role in the development of cancer, thus highlighting the need to continually develop new technologies to analyze epigenetic marks. Methylated-CpG Island Recovery Assay (MIRA), based on the high affinity of the MBD2b/MDB3L1 complex for double-stranded methylated DNA, allows for the recovery of methylated DNA without the use of bisulfite conversion or antibody recognition. MIRA is capable of detecting low-density methylation of a single methylated CpG nucleotide. This technique can be used in conjunction with microarrays or next-generation sequencing to analyze recovered methylated DNA on a genome-wide scale.
