Exosomal microRNA (miRNA) sequencing is a next generation sequencing (NGS)-based method to comprehensively detect and novel exosomal miRNAs. It can quickly identify the complete picture of the miRNAs in exosomes from different sources. Our experienced technical team provides you with sample-to-data exosomal miRNA sequencing and comprehensive bioinformatics analysis.
The exosome is a vesicle secreted by eukaryotic cells with lipid bilayer membrane of about 30-150 nm in diameter. Exosomes contain cell-specific proteins, lipids and nucleic acids, which can be transferred to other cells as signal molecules to change the function of other cells and participate in pathological processes such as immune response, antigen presentation, tumor metastasis, and nervous system. miRNA is a type of non-coding RNA of about 22nt in length. These small RNAs usually exist in body fluids such as exosomes and guide the silencing complex (RISC) to degrade mRNA or inhibit translation of mRNA through a complementary base pairing with the target mRNA. The lipid bilayer structure of exosomes can protect miRNA well, and the expression level of exosomal miRNA significantly varies with exosomal sources and physiological conditions.
We provide mature exosomal microRNA sequencing technology including sample QC, exosomal miRNA library construction, high-throughput sequencing based on Illumina HiSeq and detailed bioinformatics analysis. Millions of miRNA sequences can be obtained at one time, enabling quick identification and quantification of known and unknown exosomal miRNAs and discovery of exosomal miRNAs that are differentially expressed in different tissues, developmental stages, or disease states. Meanwhile, this technology serves as a powerful tool to study the role of exosomal miRNAs in cellular processes, and increase our understanding of the biological mechanisms of tumorigenesis, growth, invasion, and metastasis.
