RNA methylations have important epigenetic functions, and they are of great significance to study the spatiotemporal specificity of epigenetics. CD Genomics's whole transcriptome methylation sequencing is based on the long-read sequencing platforms. Combined with whole-genome bisulfite processing and bioinformatics data analysis, we perform low-cost, high-efficiency, and high-accuracy transcriptome-wide RNA methylation mapping.
Epitranscriptomics has received extensive attention in the scientific community, and it can study the effect of methylation modifications carried by RNA on gene expression. To date, more than one hundred modifications have been found on RNA. These modifications are largely distributed on non-coding RNAs (ncRNAs), especially rRNAs, tRNAs and snRNAs, and are necessary for the normal functions of ncRNAs in translation and splicing.
CD Genomics utilizes long-read sequencing platforms to achieve whole-transcriptome methylation detection. The long-read sequencing technologies of PacBio SMRT and Oxford Nanopore have the characteristics of high throughput and long read length, and have the advantages of high efficiency and single base resolution. Without the need for additional sequence amplification, the long-read sequencing can directly obtain the regional methylation information of the whole transcriptome, which provides an effective solution for assessing methylation in human, plant, microorganism and other transcriptomes. Long-read sequencing enables scientists to predict gene function and regulation as well as other key biological and clinical features more accurately.

Sample storage: Cell samples or fresh tissue pieces (cut into 5-10 mg pieces) can be treated with TRIzol or RNA protectant, frozen in liquid nitrogen, and stored at -80°C. RNA samples can be dissolved in ethanol or RNA-free ultrapure water, and stored at -80°C. Avoid repeated freezing and thawing during sample storage.
Shipping Method: When shipping RNA samples, the RNA sample is stored in a 1.5 mL Eppendorf tube, sealed with sealing film. Shipments are generally recommended to contain 5-10 pounds of dry ice per 24 hours.
