m5C individual-nucleotide resolution crosslinking and immunoprecipitation sequencing (miCLIP-m5C-seq) is a next-generation sequencing (NGS)-based method to comprehensively detect m5C, a common and abundant RNA methylation modification that exists in various transcripts. Our experienced technical team provides you with comprehensive miCLIP-m5C-seq service and professional in-depth data analysis to satisfy customer needs.
m5C is one of the common and abundant RNA methylation modifications, mainly concentrated in variable arms, anti-codon loops, and regions where rRNA binds tRNA to perform translation activity. RNA m5C modification is also dynamically reversible. Methyltransferase transfers methyl group to cytosine C to form m5C with S-adenosine methionine (SAM) as the donor. As post-transcriptional methylation, m5C can affect different stages of mRNA metabolism, including genome imprinting, silencing of retrotransposons, suppression of transposition, repetitive sequence suppression, and X chromosome inactivation. Our company provides comprehensive miCLIP-m5C-seq service, which can accurately identify the full picture of m5C modification at single-nucleotide resolution level. In this technology, mRNA is cross-linked with m5C antibody by ultraviolet light, and the antibody cross-linked RNA fragment is purified and converted into cDNA library. Later, the cDNA strand is circularized, re-linearized, amplified and sequenced. Then, crosslink-induced mutations and truncations introduced during reverse transcription are analyzed to determine precise positions of m5C throughout the transcriptome. miCLIP-m5C-seq can accurately describe and quantitatively analyze m5C, providing an integrated perspective for understanding the growth and development, biological characteristics, and gene regulation mechanisms of organisms. In the aspect of disease research, it can be applied to studies of disease mechanism, and the screening of biomarkers.
