Detection of DNA Modification Using Nanopore Sequencers

DNA modification is a crucial factor of epigenetic modification and has vital functions for gene regulation and phenotype control. A profound understanding of DNA modification requires precise mapping of the modified bases on genomic DNA. In addition to methods such as bisulfite sequencing and single-molecule real-time (SMRT) sequencing of PacBio sequencers, nanopore sequencers can be also utilized for the detection of DNA modification. Here, I will briefly review the three methods for the detection of DNA modification with nanopore sequencers and introduce a protocol using MinION and Megalodon.
