Research on N6-methyladenosine (m6A) in recent years has revealed the complex but elegant regulatory role of this RNA modification in multiple physiological processes. The advent of m6A detection technologies is the basis for studying the function of this RNA modification. These technologies enable the detection of m6A sites across transcriptome or at specific gene, thereby revealing the alternation and dynamic of RNA modification. However, non-specific signals that arise from the antibody-based methods and the low-resolution landscape have become the major drawback of classic m6A detection methods. In this review, we summarize the current available methods and categorized them into three groups according to the utilization purpose, including measurement of total m6A levels, detection m6A locus in single gene, and m6A sequencing. We hope this review helps researchers in epitranscriptomic field find an appropriate m6A detection tool that suites their experimental design.
