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.

Influenza is caused by three immunologic types of RNA viruses (A, B and C) within the Orthomyxoviridae family. Seasonal influenza is typically caused by three major subtypes of hemaglutinin (H1, H2 and H3) and two subtypes of neuraminidase (N1 and N2). A novel sub-type of influenza A virus called pandemic H1N1 2009 virus was identified in Mexico and reported by the CDC and WHO in April, 2009 (Novel swine-origin influenza A (H1N1) virus investigation team, 2009; CDC, 2009; and Fraser et al., 2009). H1N1 2009 is a novel sub-type virus that transmits easily between humans with 21 countries reporting cases within a month of initial identification (CDC, 2009-b). It is essential that public health laboratories around the world undertake detailed surveillance to monitor the spread and impact of pandemic H1N1 2009 virus as well as try to predict future changes in virulence (Fraser et al., 2009). Methods for the rapid diagnosis, case identification and tracking of this novel pathogen in the human population are therefore required to develop appropriate management strategies to mitigate morbidity and mortality.

Storage Conditions and Product Stability
All kit components can be stored for 1 year after the date of production without showing any reduction in performance.
All kit components should be stored at -20°C upon arrival. Repeated thawing and freezing (> 2 x) of the Master Mix and Positive Control should be avoided, as this may affect the performance of the assay. If the reagents are to be used only intermittently, they should be frozen in aliquots.
