Introduction of Global RNA m6A Quantification

In eukaryotes, 5′-end Cap and 3′-ployA modification play an important role in transcriptional regulation. Currently, known types of enzymes involved in the modification of N6-methyladenosine (m6A) that are already known include demethylases, methylases, and methylation recognition enzymes. An abnormality in the enzyme involved in m6A modification will cause abnormal methylation in RNA, which leads to a series of diseases including obesity, tumor, neurological disease, and embryonic developmental delay. In addition, some non-coding RNAs such as lncRNA, tRNA, rRNA and splicing RNA also have a large number of base modification activities before and after transcription. These physiological processes can regulate gene expression and mediate RNA translation. Because the levels of m6A are changed in eukaryotic cells of different types and different states, quantitative detection of m6A modification in the transcriptome can provide researchers with a large amount of bioinformatics data, which is also beneficial for the diagnosis and treatment of diseases.

m6A RNA methylation modification can be quantitatively detected by both colorimetric and fluorescent methods, which is suitable for direct detection of total RNA methylation status isolated from any species, such as mammals, plants, fungi, bacteria and viruses. In this assay, RNA samples are incubated with the antibodies that can specifically capture N6-methyladenosine. The absorbance is read at a wavelength of 450 nm in a spectrophotometer while the detection signal is enhanced and then quantified by colorimetry. The amount of m6A is proportional to the measured OD intensity. Alternatively, the RFU (relative fluorescence unit) is read in a fluorescence spectrophotometer for fluorescence measurement. And the amount of m6A is also proportional to the measured fluorescence intensity.
