CO00021 Midstream Cassette 126x15mm, pink

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.

endo-BCN-PEG8-acid is a BCN-containing crosslinker reagent. The terminal carboxylic acid is reactive with primary amine groups in the presence of activators (e.g. EDC, or HATU). The BCN group enable copper free click chemistry with azide -tagged biomolecules. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose.
