Exosomes are tiny membrane-bound extracellular vesicles produced in the endosomal compartment of most eukaryotic cells and can be found in abundance in many and perhaps all body fluids including blood, urine, cerebrospinal fluid. These tiny vesicles contain distinct subsets of proteins, lipids, DNA, and RNA (including microRNAs, mRNAs, lncRNAs and other ncRNAs). Exosomes have a unique biogenesis pathway via multivesicular bodies and may play an important role in cell-to-cell signaling, thereby influencing the immune system and mediating adaptive immune responses to pathogens and tumors. The delivery of their cargo RNA molecules is a mainstream hypothesis to explain biological effects.
Exosomes contain RNA, proteins, lipids, and metabolites that reflect the type of cell origin. Thus, proteomics, transcriptomics, and metabonomics are often performed for large-scale analyses of exosomes. With the advent of next-generation sequencing technology, exosome research is accelerating not only in cancer, but also in various diseases. It has been found that exosomes, based on their specific membrane and cytoplasmic proteins, as well as other protein subsets, may be associated with different types of cell-related functions and may also be associated with human diseases. Knowledge of exosome RNA sequencing not only helps to understand their biological roles, but analysis of exosome RNA-Seq data based on bioinformatics can provide a new way to search for new disease-related biomarkers in the body fluids of patients. CD Genomics provides high-throughput sequencing services to quickly and efficiently obtain the global information of exosomal RNAs. Our one-step exosomal RNA sequencing services cover the detailed analysis of all types of exosomal RNA, including exosomal small RNA (mainly exosomal microRNA), exosomal lncRNA, exosomal circRNA, and exosomal mRNA).
Explore how biofluid profiling using NGS helps researchers understand dynamics and interactions of exosomal RNA.
Our exosomal microRNA sequencing examines monitor global microRNA expression at an affordable price, enabling the identification of biomarkers associated with diseases like cancer.
Learn MoreExosomal small RNA sequencing is a powerful tool for analyzing small RNAs including miRNAs, piRNAs and siRNAs, offering both quantitative and qualitative information.
Learn MoreExosomal lncRNA sequencing examines global lncRNAs in exosomes. As exosomal lncRNAs are involved with tumorigenesis, tumor angiogenesis, and chemoresistance, this service can detect promising biomarkers for cancer.
Learn MoreExosomal long RNA-seq analyzes mRNAs, long non-coding RNAs, and circular RNAs in the sample, enabling alternative splicing analysis and detection of novel transcripts, and gene fusion events.
Learn MoreExosomal mRNA sequencing service can not only help you to profile exosomal mRNA with regard to the expression levels and dynamics but also understand the physiological roles, with or without knowledge of priori sequences.
Learn MoreExosomal cicrRNA-Seq can quickly and efficiently obtain global information on exosomal circRNAs. Our single-base resolution technology allows the detection of circRNAs from very small amounts of cellular material.
