“…This is partly due to the fact that detection of m 6 A at specific sites in a sequence is challenging. So far detection of N 6 -methyladenine in DNA has been demonstrated using a single-molecule, real-time sequencing method. , Detection of N 6 -methyladenosine in RNA has been shown using (1) nuclease cleavage followed by thin-layer chromatography (TLC) or mass spectrometry (MS), (2) immunocapturing of m 6 A-containing RNA fragments followed by sequencing, (3) ligation, and (4) a selective polymerase . However, these methods are laborious (e.g., require multiple steps to identify a single site), time-consuming (e.g., TLC and MS), and high-cost (e.g., enzymatic reaction).…”
