Exosomes are endosome-derived small membrane vesicles with diameters less than 150 nm that are present in nearly all biological fluids (e.g., blood, breast milk, saliva and urine). The exosomes contain not only protein components, but also some RNA components, such as microRNA (miRNA), long non-coding RNA (lncRNA) and messenger RNA (mRNA), and circular RNA (circRNA). These RNAs carried by exosomes are collectively called exosomes-derived RNAs, which have a complete sequence structure and biological activity.

Overview of Our Exosome RNA-Seq Service
CD Genomics adopts the method of ribosome removed library construction to the whole transcriptome sequencing service of exosomes. We can simultaneously detect lncRNA, mRNA and circRNA in samples to obtain comprehensive transcriptome information, and then carry out expression analysis, structural research, variation research and discovery of new transcripts for different types of RNA.
Service Portfolio
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.
Exosomal small RNA sequencing is a powerful tool for analyzing small RNAs including miRNAs, piRNAs and siRNAs, offering both quantitative and qualitative information.
Exosomal 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.
Exosomal 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.
Exosomal 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.
Exosomal 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.
