Abstract

A method for detecting hydroxymethylation modification in nucleic acid comprises: glycosylating the nucleic acid, digesting with MspI, ligating the digested fragments to a biotin-labeled linker at both ends thereof, digesting with NlaIII; capturing the digested fragments using streptavidin magnetic beads to produce fragments having the biotin-labeled linker at one end and a CATG 4-base sticky end at the other end, wherein these fragments reveal modification information of their adjacent CCGG sites; ligating the CATG sticky end to a linker containing a recognition site of MmeI or Ecop15I, digesting with corresponding restriction endonuclease to produce short sequence fragments that can reveal modification information of their adjacent CCGG sites; and performing a tag number comparison to obtain information about methylation and hydroxymethylation modification relative levels. A use of the method is also provided.
