Norgen’s Exosome Purification and RNA Isolation Kits constitute all-in-one systems for the purification of exosomes and the subsequent isolation of exosomal 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 in that they do 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 free from any protein-bound circulating RNA and of the highest integrity. 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 shipment. 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.

FFPE samples are incubated in an optimized lysis buffer, which results in the release of RNA and precipitation of DNA. After centrifugation, the RNA-containing supernatant and DNA-containing pellet are then processed separately to purify RNA and DNA. After adding magnetic particles and binding solution, DNA/RNA will be adsorbed on the surface of magnetic particles, and impurities such as proteins will be removed without adsorption. The adsorbed particles were washed with washing solution to remove proteins and impurities, washed with ethanol to remove salts, and finally DNA/RNA was eluted by RNase Free Water.

Storage and Stability
Proteinase K and MagBind Particles should be stored at 2-8°C upon arrival. However, short-term storage (up to 24 weeks) at room temperature (15-25°C) does not affect their performance. The remaining kit components can be stored at room temperature (15-25°C) and are stable for at least 18 months under these conditions.

Hipure silica gel column is based on glass fiber filter membrane with high binding force. Under the condition of high concentration of ionizing agent (such as guanidine hydrochloride or guanidine isothiocyanate), the filter membrane can adsorb nucleic acid through hydrogen bond and electrostatic, while protein and other impurities are not adsorbed and removed. The filter membrane adsorbed with nucleic acid is washed to remove the residual protein and salt. Finally, the nucleic acid adsorbed on the filter membrane can be washed out with low salt buffer (such as buffer TE) or water. The obtained nucleic acid has high purity and can be directly used in various downstream experiments.
