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.
Norgen’s Plasma/Serum Exosome and RNA Isolation Mini Kit
For sample volumes ranging from 50 µL to 1 mL. This kit allows the user to elute into a flexible elution volume ranging from 50 µL to 100 µL.
Norgen’s Plasma/Serum Exosome and RNA Isolation Midi Kit
For sample volumes ranging from 1 mL to 4 mL. This kit allows the user to elute into a flexible elution volume ranging from 50 µL to 100 µL.
Norgen’s Plasma/Serum Exosome and RNA Isolation Maxi Kit
For sample volumes ranging from 4 mL to 10 mL. This kit allows the user to elute into a flexible elution volume ranging from 50 µL to 100 µL.

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.

This kit provides a fast and simple spin column procedure for isolating genomic DNA from saliva samples collected and preserved using Norgen’s Saliva DNA Collection and Preservation Devices (Cat. 49000), as well as fresh saliva samples.
Saliva DNA purified using Norgen’s Saliva DNA Isolation Kit Dx kit is of the highest quality, and can be used with any downstream in vitro diagnostic application employing enzymatic amplification or other enzymatic modifications of DNA followed by signal detection or amplification.
Background
Saliva represents an excellent non-invasive alternative to blood collection. Human genomic DNA extracted from buccal epithelial cells and white blood cells found in saliva can be used in various applications in diagnostics. Saliva DNA can be used for the detection of biomarkers to diagnose a disease, follow the diseases progress or monitor the effects of a particular treatment. Saliva DNA can also be used to diagnose particular types of infections. Isolation of DNA from saliva has become an attractive alternative to isolation from blood or tissue due to the fact that sample collection is non-invasive, the samples can be collected by individuals with little training, and no special equipment is required. Norgen’s Saliva DNA Isolation Kit provides a fast and simple procedure for isolating genomic DNA from both preserved saliva samples and fresh saliva samples.
