Reduced-Representation M.SssI Methylase-Assisted Bisulfite Sequencing

RRMAB-seq is based on the pretreatment of gDNA with the enzyme MspI, which recognizes and cuts the CCGG consensus to enrich CpG-rich regions, like gene promoters (Neri et al., 2015). This method is an adapted version of MAB-seq (Wu et al., 2014)


  • Increased coverage of CpG-rich regions reduces sequencing costs and increases read depth
  • Reduced number of chemical or enzymatic DNA treatments required before bisulfite treatment


  • Unable to distinguish 5fC/5caC from unmodified C within a non-CpG context (Neri et al., 2015)
