Methylated-CpG Island Recovery Assay (MIRA)

MIRA uses the high affinity of a methylated-CpG-binding protein complex (MBD2B and MBD3L1) to enrich regions with methylated CpG dinucleotides (Rauch et al., 2010). This approach can be applied to both array-based DNA analysis and NGS, which are sometimes distinguished as MIRA-chip (Jung et al., 2015) and MIRA-seq (Rauch et al., 2010).

In this procedure, the fragmented gDNA is incubated with purified GST-MBD2B and His-MBD3L1 proteins. The high-affinity MBD2B/MBD3L1 complex binds to the methylated gDNA templates. The methylated gDNA fragments are captured on glutathione-coated magnetic beads. The enriched methylated DNA fraction is amplified, labeled, and analyzed by NGS.


  • High specificity and sensitivity, requiring as little as 1 ng input gDNA
  • Does not require DNA denaturation
  • Independent of restriction sites


  • Resolution limited to 100 bases
  • Requires a minimum of 2 methylated CpGs in the captured fragment Rauch et al., 2011)
