[RI1001] RNAok™ RNase Inhibitor, 20 U/μl, 2000 U x 5

The RNAok™ RNase Inhibitor is a recombinant mammalian RNase inhibitor which possesses very high affinity for eukaryotic pancreatic-type ribonuclease. The RNAok™ RNase Inhibitor forms a 1:1 complex with pancreatic RNase A by noncovalent binding, presenting a noncompetitive inhibitory activity on these pancreatic enzymes. RNAok™ RNase Inhibitor is active against RNase A, RNase B, RNase C but not RNAse H, RNase I, RNase T1, RNase T2, and S1 nuclease. RNAok™ RNase Inhibitor is compatible with RT-PCR enzymes such as AMV, M-MLV and ExcelRT™ Reverse Transcriptase or Taq DNA polymerase.

Overview

Purification and enrichment of intact plasma/serum exosomes for functional studies
Isolate all sizes of RNA, including microRNA, irrespective of size or GC content, without bias
Versatile plasma/serum input volume
No phenol extractions, Proteinase K treatment, nor carrier RNA required
No time-consuming ultracentrifugation, filtration nor special syringes required
No precipitation reagents, nor overnight incubation required
Compatible with plasma/serum from most species
Pure exosomes are purified and are free from any other RNA-binding proteins
Purification is based on spin column chromatography that uses Norgen’s proprietary resin
The purified RNA is suitable for a variety of downstream applications, including Small RNA Sequencing. Find out more information on Norgen’s NGS services

Norgen’s Plasma/Serum Exosome and RNA Isolation Kits constitute all-in-one systems for the purification of exosomes and the sequential isolation of exosomal RNA from different plasma/serum 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. The RNA isolated from the purified exosomes is free from any protein-bound circulating RNA and is 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 solutions 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
This kit is suitable for the purification of exosomes from fresh or frozen serum or plasma prepared from blood collected on either EDTA or Citrate. Plasma samples prepared from blood collected on heparin should not be used as heparin can significantly interfere with many downstream applications such as RT-PCR.
