Exosomal RNA Isolation Kit

Product Description

• Isolate all sizes of exosomal and extracellular vesicle RNA, including microRNA
• ​Bind and elute all RNA irrespective of size or GC content, without bias
• No phenol extractions
• No Proteinase K treatment
• No carrier RNA
• Concentrate isolated RNA into a flexible elution volume ranging from 50 µL to 100 µL
• Purify high-quality RNA in 15-20 minutes

This kit provides a fast, reliable and convenient method to isolate and concentrate exosomal RNA from exosomes previously purified using Norgen's Urine Exosome Purification Kits or Norgen's Plasma/Serum Exosome Purification Kits. This kit also allows for the isolation of RNA from intact extracellular vesicles (EVs) purified from different urine or plasma/serum sample volumes. The purification is based on Norgen’s proprietary resin.

The Exosomal RNA Isolation Kit is designed to isolate all sizes of extracellular vesicle RNA, including microRNA. The kit provides a clear advantage over other available kits in that it does not require any special instrumentation, protein precipitation reagents, extension tubes, phenol/chloroform or protease treatments. Moreover, the kit allows the user to elute into a flexible elution volume ranging from 50 µL to 100 µL. The purified RNA is of the highest integrity, and can be used in a number of downstream applications including real time PCR, reverse transcription PCR, Northern blotting, RNase protection and primer extension, and expression array assays.

Performance Data

Figure 1. Isolation of RNA from exosomes purified from different urine volumes. Norgen's Exosomal RNA Isolation Kit (Cat# 58800) was used to isolate RNA from exosomes isolated from different urine volumes purified using Norgen's Urine Exosome Purification Kits (Cat# 57700, 57800 and 57900). Two microlitres of the isolated RNA was then used as the template in RT-qPCR reactions to assess the amplification of the isolated urinary exosomal miR-30a. (A) The urinary exosomal miR-30a is linearly decreasing with increasing the sample input volume. B) The relative amount of the urinary exosomal miR-30a shows excellent linearity with a percentage of recovery of more than 90%.

Figure 2. Isolation of RNA from exosomes purified from different plasma volumes. Norgen's Exosomal RNA Isolation Kit (Cat# 58800) was used to isolate RNA from exosomes isolated from different plasma volumes purified using Norgen's Plasma/Serum Exosome Purification Kits (Cat# 57400, 57500 and 57600). Two microlitres of the isolated RNA was then used as the template in RT-qPCR reactions to assess the amplification of the isolated plasma exosomal miR-26a. (A) The plasma exosomal miR-26a is linearly decreasing with increasing the sample input volume. B) The relative amount of the plasma exosomal miR-26a shows excellent linearity with a percentage of recovery of more than 90%.
