Overview
Isolate all sizes of RNA, including microRNA, irrespective of size or GC content, without bias
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 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.
Disulfide Biotin alkyne is an azide-activated cleavable biotin probe that allows for efficient recovery of avidin-bound protein complexes in affinity-based assays. This reagent contains a biotin moiety linked to an alkyne group through a spacer arm containing a cleavable disulfide linker. Under reducing conditions (50 mM dithiothreitol, 10 mM 2-mercaptoethanol or 1% sodium borohydride), the disulfide bonds are cleaved, releasing the biotin tag and any avidin conjugate bound to it.

The Opentrons Temperature Module, compatible with both the OT-2 and Flex Robots, is a fully automated thermoelectric module and integrated for use with the Opentrons platform. It is used to achieve temperature changes ranging from 4 to 95°C for various applications.
The Temperature Module GEN2 is compatible with the new Opentrons Flex Robot when paired with the Flex Temperature Caddy and Calibration Adapter. The caddy sits below the deck to enable below-deck cable routing and labware placed on modules remain closer to the deck surface. The calibration adapter is used to calibrate the location of the module. If you choose to include the Opentrons Flex Caddy and Calibration Adapter, your order will ship in 20 business days.
