• Versatile sample input ranges
• Isolate all sizes of free-circulating RNA, including microRNA​
• Bind and elute all RNA irrespective of size or GC content, without bias
• The purified exosomal RNA is free from any circulating RNA-binding proteins
• No phenol extractions, Proteinase K treatment nor carrier RNA required
• No time-consuming ultracentrifugation, filtration nor special syringes are required
• No precipitation reagents nor overnight incubation required
• Concentrate isolated exosomal RNA and free-circulating RNA into a flexible elution volume ranging from 50 µL to 100 µL
• Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix

These kits provide a fast, reliable and convenient method to sequentially isolate and concentrate exosomal RNA as well as Free-Circulating RNA from different urine sample volumes. The purification is based on spin column chromatography that employs Norgen’s proprietary resin. These kits are designed to isolate all sizes of RNA, including microRNA, irrespective of size or GC content, without bias. These kits provide a clear advantage over other available kits since they do not require any special instrumentation, protein precipitation reagents, extension tubes, phenol/chloroform or protease treatments. Moreover, the kits allow the user to elute into a flexible elution volume ranging from 50 µL to 100 µL. The RNA isolated from the purified exosomes is free from any protein-bound circulating RNA and is of the highest integrity. Moreover, the free-circulating, protein-bound, RNA is free from any exosomal RNA. The purified RNA 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.

Storage Conditions and Product Stability
All buffers should be kept tightly sealed and stored at room temperature. This kit is stable for 2 years after the date of shipping. It is recommended to warm Lysis Buffer A for 20 minutes at 60°C if any salt precipitation is observed.

Important Note
Urine samples stored at -70°C, -20°C or at 4°C will develop some precipitation due to the aggregation of some of the highly abundant proteins in urine. Eliminating these precipitates using centrifugation or filtration may cause the loss of exosomes. Furthermore, these precipitates may affect the quality of the purified nucleic acid. We recommend the use of Norgen’s Urine Preservative when collecting urine samples, which is designed for the preservation of nucleic acids and proteins in fresh urine samples at ambient temperatures. The components of the Urine Preservative allow samples to be stored for over 2 years at room temperature with no detected degradation of urine DNA, RNA or proteins. Norgen’s Urine Preservative is available as a liquid format in Norgen’s Urine Preservative Single Dose Ampules, as well as in a dried format in Norgen’s Urine Collection and Preservation Tubes.

Overview

• Purification and enrichment of intact exosomes from plasma, serum, urine, cell culture media and saliva in less than 30 minutes.
• Versatile sample input ranging from 50 µL to 10 mL
  • Plasma/Serum Exosome Purification Mini Kit (50 µL – 1 mL Plasma/Serum)
  • Plasma/Serum Exosome Purification Midi Kit (1 mL – 4 mL Plasma/Serum)
  • Plasma/Serum Exosome Purification Maxi Kit (4 mL – 10 mL Plasma/Serum)
• Exosome purification is based on Norgen’s proprietary resin separating matrix through exosomes’ surface proteins.
• No precipitation reagents, overnight incubation, protease or coagulant treatments required
• No time-consuming ultracentrifugation, filtration or special syringes required
• Purify intact exosomes with a size ranging from 40-200 nm depending on sample input type
• Purified exosomes are compatible with functional studies.
• Purified exosomes are free from any RNA-binding proteins
• Purified exosomes are compatible with NanoSight® or Electron Microscopy for assessing the approximate exosome size range and concentration.
• Exosomal RNA can be extracted from the purified exosomes using Norgen’s Exosomal RNA Purification technology or any other RNA extraction method.

The Plasma/Serum Exosome Purification Kits provide a fast, reliable and convenient method to purify and enrich for intact exosomes from different plasma/serum sample volumes ranging from 50 µL to 10 mL. These kits also allow for the purification of intact extracellular vesicles (EVs) from different plasma/serum sample volumes, and these EVs are ready for any downstream application. The purification is based on Norgen’s proprietary resin.

These kits provide a clear advantage over other available methods since they do not require any special instrumentation, ultracentrifugation, precipitation reagents or any protease treatments. More importantly, the purified exosomes will not be contaminated with any other RNA-binding proteins that may contaminate your exosomal RNA, which is essential if studying exosomal transcripts.

NanoSight® Analysis

Exosomes enriched with Norgen’s Plasma/Serum Exosome Purification Kits can be analyzed using NanoSight® for assessing the approximate exosome size range and concentration

Exosomal RNA Analysis

To purify exosomes and isolate exosomal RNA, choose the Plasma/serum Exosome Purification and RNA isolation kits. The protocol is divided into 2 parts and an aliquot of purified exosomes can be taken for applications like NTA/TEM etc. before processing them for RNA isolation. Or you can use the Exosomal RNA Isolation Kit if you’ve already purified exosomes using a Norgen kit or another method. . Exosomal RNA isolation is based on Norgen’s proprietary resin without the need for phenol extractions or carrier RNA. This RNA is ideal for gene expression analysis using RT-qPCR, microarray, or NGS and for biomarker discovery.
