m7G-methylated RNA immunoprecipitation sequencing (m7G MeRIP sequencing) is a next generation sequencing (NGS)-based method to comprehensively detect m7G, an RNA methylation modification that exists in various transcripts. Our m7G MeRIP sequencing service is dedicated to detecting and analyzing m7G RNA modification in a sample, providing a powerful tool for research of intracellular translation, regulation and protein modifications.
N7-methylguanosine (m7G), present at eukaryotic mRNA 5’ caps and at defined internal positions within tRNAs and rRNAs, is an essential positively charged modification in eukaryotes. It is involved in regulating nearly every step of the life cycle of mRNA such as mRNA export, translation, and splicing. Besides, m7G can regulate miRNA biosynthesis and biological functions, tRNA stability, and intracellular processing and maturation of 18S rRNA. As a new type of RNA methylation modification, m7G RNA methylation is a hot spot in epigenetic transcriptome. Accurate identification of the m7G sites in transcriptome will provide insights into its biological functions and mechanisms. m7G MeRIP sequencing is a high-throughput sequencing method based on antibody immunoprecipitation. It can quickly generate the complete transcriptome-wide picture of internal m7G methylome in biological samples from different sources. The technique uses an m7G-specific antibody to grab methylated modified fragments for library preparation and carries out high-throughput sequencing and peak localization for m7G modified fragments. Our experienced technical team can comprehensively detect m7G methylation modification levels of various RNA molecules such as mRNA, lncRNA, pri-miRNA, tRNA and rRNA, and provides professional and in-depth data analysis of m7G RNA methylation.
