The Plasma/Serum Exosome Purification Kits provide a fast, reliable and convenient method to purify and enrich for intact exosomes from different plasma/serum sample volumes ranging from 50 µL to 10 mL. These kits also allow for the purification of intact extracellular vesicles (EVs) from different plasma/serum sample volumes, and these EVs are ready for any downstream application. The purification is based on Norgen’s proprietary resin.
These kits provide a clear advantage over other available methods since they do not require any special instrumentation, ultracentrifugation, precipitation reagents or any protease treatments. More importantly, the purified exosomes will not be contaminated with any other RNA-binding proteins that may contaminate your exosomal RNA, which is essential if studying exosomal transcripts.
NanoSight® Analysis
Exosomes enriched with Norgen’s Plasma/Serum Exosome Purification Kits can be analyzed using NanoSight® for assessing the approximate exosome size range and concentration
Exosomal RNA Analysis
To purify exosomes and isolate exosomal RNA, choose the Plasma/serum Exosome Purification and RNA isolation kits. The protocol is divided into 2 parts and an aliquot of purified exosomes can be taken for applications like NTA/TEM etc. before processing them for RNA isolation. Or you can use the Exosomal RNA Isolation Kit if you’ve already purified exosomes using a Norgen kit or another method. . Exosomal RNA isolation is based on Norgen’s proprietary resin without the need for phenol extractions or carrier RNA. This RNA is ideal for gene expression analysis using RT-qPCR, microarray, or NGS and for biomarker discovery.

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.
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.

Volcano3G® RT-PCR Probe 2x Master Mix contains all components required for general RT-qPCR
– optimized reaction mix for sensitive and reliable results
– engineered, truly thermostable Taq DNA polymerases with reverse transcriptase activity
– fast start function due to a hotstart aptamer formulation which prevents unspecific amplification at lower temperatures (<57°C)
– Pipetting aid in form of a blue dye for better visibility during aliquoting into well-plates
– included lysis function*
* = A sample extraction and sample lysis is not necessary as immediate hot PCR cycling conditions can brake cell- and virus membranes. Please see our published references to this product.
Note: Volcano3G® RT-PCR Probe 2x Master Mix is a unique master mix. If you are using it for the first time, we recommend to design primers to have higher melting/annealing temperatures (above 65°C). Additionally, for assay setup it is advised to perform RT-PCR test reactions with temperature gradients (i.e., for the annealing and extension steps) to identify the most proficient PCR protocol for your needs using our Volcano DNA polymerase products.
For research use and further manufacturing.
