Efficient Exosomal RNA Extraction from 100–200 μL Exosome SamplesDesigned for concentrated RNA recovery from purified exosome suspensions using a silica column-based purification workflow.The Exosome RNA Extraction Kit is designed for the isolation and concentration of RNA from purified exosome suspensions. It is suitable for processing 100–200 μL of exosome sample and provides a simple column-based workflow for recovering exosomal RNA.
The purification system is designed to efficiently recover small RNA fragments while removing lipids, proteins and other contaminants. Following purification, exosomal RNA is eluted into a small volume of 30–50 μL RNase-free Water, providing a concentrated RNA preparation for downstream molecular biology applications.
The purified RNA can be used directly for RT-PCR, real-time RT-PCR, Northern blot and microarray analysis.
Designed for 100–200 μL purified exosome suspensions
Efficient recovery of exosomal RNA, including small RNA fragments
Silica column-based purification
Lipids, proteins and other contaminants are removed during purification
No chloroform extraction required
RNA can be concentrated into 30–50 μL of RNase-free Water
Complete extraction workflow in approximately 1 hour
Suitable for RT-PCR, real-time RT-PCR, Northern blot and microarray analysis
The kit uses a column-based RNA purification workflow:
Exosome Sample → Lysis → RNA Precipitation/Binding → Column Purification → Washing → Elution
For a standard 100 μL exosome suspension, Buffer TL is added to disrupt the sample matrix, followed by Buffer EX treatment and centrifugation. Ethanol is then added to the recovered supernatant before loading onto the nucleic acid purification column.
The column retains RNA while washing steps remove residual contaminants. After a final drying centrifugation, RNA is eluted using 30–50 μL RNase-free Water.

Step 1. Sample Treatment
Add 700 μL Buffer TL to 100 μL of purified exosome suspension and mix thoroughly.
For 200 μL of exosome suspension, use 1.4 mL Buffer TL according to the sample-volume ratio.
Step 2. Exosome Processing
Add Buffer EX according to the sample volume, mix thoroughly and centrifuge at 4°C, 12,000 rpm for 15 minutes.
Step 3. RNA Binding Preparation
Transfer the supernatant and add 2 volumes of absolute ethanol. Mix thoroughly.
Step 4. Column Purification
Load the mixture onto the nucleic acid purification column. Multiple loading cycles can be performed when processing larger sample volumes.
Step 5. Washing
Wash the column sequentially with Buffer WA and Buffer WBR to remove residual contaminants.
Step 6. Drying and Elution
Centrifuge at high speed to remove residual ethanol, then elute the purified RNA with 30–50 μL RNase-free Water.
Step 7. Downstream Applications
The purified exosomal RNA can be used immediately for downstream molecular biology experiments or stored below −70°C.
The purified exosomal RNA can be used for:
RT-PCR
Real-time RT-PCR
Northern blot
Microarray analysis
Exosome RNA research
Extracellular vesicle molecular biology research
