Overview

• Ensure optimal results for sensitive applications like NGS
• Up to a tenfold increase in microRNA mapping during sequencing runs to reduce costs
• The purified exosomal RNA is free from any circulating RNA-binding proteins.
• No phenol extractions, Proteinase K treatment, nor carrier RNA.
• No time-consuming ultracentrifugation, filtration nor special syringes are required.
• Concentrate isolated RNA into a flexible elution volume ranging from 50 μL to 100 μL.
• Purification is based on EXTRAClean spin column chromatography that uses Norgen’s proprietary separation matrix.

Norgen’s EXTRAClean Plasma/Serum Exosome and Free-Circulating RNA Isolation Kit constitutes an all-in-one system for the purification of exosomes and the sequential isolation of RNA and free-circulating RNA from different plasma/serum sample volumes ranging from 50 μL and up to 10 mL. The purification is based on spin column chromatography that employs Norgen’s proprietary resin. The EXTRAClean columns undergo stringent processing and rigorous quality control measures to minimize contamination traces, ensuring optimal results for sensitive applications such as NGS. The kit is designed to isolate all sizes of RNA, including microRNA. The kit provides a clear advantage over other available kits in that they do not require any special instrumentation, protein precipitation reagents, extension tubes, phenol/chloroform or any protease treatments. Moreover, the kit allows 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, NGS application, reverse transcription PCR, Northern blotting, RNase protection and primer extension, and expression array assays.

Principle

This product is based on the purification method of high binding magnetic particles. The sample is lysed and digested under the action of lysate and Protease. DNA is released into the lysate. After adding magnetic particles and binding solution, DNA 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 was eluted by Elution Buffer.

Advantages

• High binding force – suitable for handling DNA rich samples, such as whole blood, buffy coat, concentrated blood, etc.
• High purity – carboxyl magnetic beads with weak surface adsorption, getting higher purity
• General – can be used for various clinical samples

Storage and Stability

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