Exosomal RNA Sequencing Service

N2Jenomics Lab Pvt. Ltd. offers comprehensive Exosomal RNA Sequencing services to profile RNA cargo within extracellular vesicles (EVs). Our end-to-end workflow includes exosome isolation, RNA extraction, library preparation, next-generation sequencing, and advanced bioinformatics, enabling researchers to investigate intercellular communication, discover biomarkers, and understand disease mechanisms.

What Is Exosomal RNA Sequencing?

Exosomes are small extracellular vesicles secreted by most cell types and found in biological fluids such as blood, plasma, serum, urine, saliva, and cell culture media. They carry a diverse range of RNA molecules—including mRNA, microRNA (miRNA), long non-coding RNA (lncRNA), and other non-coding RNAs—that reflect the physiological and pathological status of their cells of origin.

Exosomal RNA sequencing enables comprehensive analysis of these RNA molecules, providing a powerful, minimally invasive approach for biomarker discovery, disease monitoring, and studies of cell-to-cell communication.

Advantages of Exosomal RNA Sequencing

• Non-Invasive Sampling

Analyze RNA from easily accessible biofluids, reducing the need for invasive tissue biopsies.

1. What is the role of exosomes in RNA biology?

Exosomes are small extracellular vesicles that transport RNA molecules between cells, playing a key role in cell-to-cell communication. By delivering functional RNAs to recipient cells, they regulate gene expression, immune responses, and various physiological and pathological processes. Since exosomal RNAs reflect the molecular characteristics of their cells of origin, they are valuable biomarkers for disease diagnosis, prognosis, and therapeutic monitoring.

2. What types of RNA are present in exosomes?

Exosomes contain a diverse range of RNA molecules, including:

• • Messenger RNA (mRNA)

• • MicroRNA (miRNA)
• • Long non-coding RNA (lncRNA)
• • Transfer RNA (tRNA)
• • Circular RNA (circRNA)
• • Other small non-coding RNAs

The RNA composition varies depending on the originating cell type, physiological conditions, and disease state, making exosomal RNA an important resource for biomarker discovery and functional studies.

3. Should I choose a low-input or standard library preparation method?

The choice of library preparation depends on the quantity and quality of the input RNA.

• • Standard library preparation is recommended when sufficient high-quality RNA (typically ≥100 ng) is available, providing broader transcript coverage and improved sequencing performance.
• • Low-input library preparation is designed for samples with limited RNA while maintaining high sensitivity and reliable transcriptome profiling.

Our scientists can recommend the most appropriate library preparation strategy based on your sample type and research objectives.

4. Which sample is preferred for exosome studies: plasma or serum?

Plasma is generally recommended for exosome research. During serum preparation, platelet activation can release additional extracellular vesicles, potentially affecting exosome abundance and composition. Plasma minimizes this effect and provides a more representative profile of circulating exosomes for biomarker discovery and disease research.

5. What factors are important for successful exosomal RNA sequencing?

High-quality exosomal RNA sequencing depends on several critical factors:

• • Proper sample collection and storage
• • Efficient exosome isolation with minimal contamination
• • High-quality, intact RNA extraction
• • Appropriate library preparation and sequencing strategy
• • Robust bioinformatics analysis for accurate data interpretation

Following these best practices helps ensure reliable, reproducible, and biologically meaningful results.

6. What type of library is used for exosomal RNA sequencing?

For comprehensive exosomal RNA profiling, we typically prepare strand-specific, rRNA-depleted cDNA libraries from DNA-free RNA. Depending on the study objectives, library preparation can also be customized for specific RNA classes, including total RNA, mRNA, microRNA (miRNA), or other small RNAs, ensuring optimal sequencing performance for each application.
