Storage and Stability
Proteinase K, RNase A should be stored at 2-8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15-25°C) does not affect their performance. The remaining kit components can be stored at room temperature (15-25°C) and are stable for at least 18 months under these conditions.
*Note:Leukocyte protocol can be used when large volume whole blood samples need to be processed. Whole blood was treated with red blood cell lysate, and white blood cells were obtained by centrifugation before extraction

Purification and enrichment of intact exosomes from plasma, serum, urine, cell culture media and saliva in less than 30 minutes.
Versatile sample input ranging from 50 µL to 10 mL
Plasma/Serum Exosome Purification Mini Kit (50 µL – 1 mL Plasma/Serum)
Plasma/Serum Exosome Purification Midi Kit (1 mL – 4 mL Plasma/Serum)
Plasma/Serum Exosome Purification Maxi Kit (4 mL – 10 mL Plasma/Serum)
Exosome purification is based on Norgen’s proprietary resin separating matrix through exosomes’ surface proteins.
No precipitation reagents, overnight incubation, protease or coagulant treatments required
No time-consuming ultracentrifugation, filtration or special syringes required
Purify intact exosomes with a size ranging from 40-200 nm depending on sample input type
Purified exosomes are compatible with functional studies.
Purified exosomes are free from any RNA-binding proteins
Purified exosomes are compatible with NanoSight® or Electron Microscopy for assessing the approximate exosome size range and concentration.
Exosomal RNA can be extracted from the purified exosomes using Norgen’s Exosomal RNA Purification technology or any other RNA extraction method.
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.
Variable depending on the plasma/serum input volume
Time to Complete 10 Purifications
15 – 30 minutes
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.
NGS Cell Free DNA Library Prep Kit (illumina and MGI Platforms)
Product Info

Product Info
The NGS Cell Free DNA Library Prep Kit (illumina and MGI Platforms) was developed for the construction of high quality cell-free DNA (cfDNA) libraries using 1 ng to 50 ng of cell-free DNA as input. The kit has a simple work flow and a fast procedure. Multiplexing of the cell free DNA library is possible based on the index type.
NGS Cell Free DNA Library Prep Kit Workflow
The main source of cell-free DNA (cfDNA) is derived from apoptotic hematopoietic cells in blood and found in the plasma. The length of the cfDNA is about 150-200 bp in length. Circulating tumor DNA (ctDNA) derived from malignant tumors is a part of cfDNA. Both cfDNA and ctDNA can be used as a noninvasive biomarker since it offers a better approach in comparison to invasive tissue biopsies.
NGS has been used for cfDNA and ctDNA sequencing in the field of liquid biopsy as it provides a whole genome level of molecular profiling. One of the hurdles for cfDNA sequencing is the difficulty of library preparation from the limited amount of cfDNA obtained from plasma. Our cell-free NGS kit makes it easy to get enough libraries from limited input in just 1.5 hours.
Three index types are available for the NGS Cell Free DNA Library Prep Kit of the illumina platform:
Non-index (Cat.# 30029): Libraries do not have index.
Index(Cat.# 30031): Each of our index primers contains a unique 6-base index sequence that can be used for sample identification. Total 48 library multiplexing is possible. Index information can be downloaded here.
Unique dual index (Cat.# 30033): Cell-free DNA library multiplexing up to 96 samples is possible with the unique dual indexes. We have developed a Four-Base Difference Index System. The system have at least 4 bases different from each other in the 8 bases index length. The primers effectively minimize sequencing errors such as mis-assignment, index hopping, index contamination etc. Index information can be downloaded here.
Indexes are available for the MGI platform kits (Cat.# 34031).
Kit advantages:
Fast and simple protocol
Hands-on time is around 10 minutes
The total protocol time is only 1.5 hours
Easy procedure based on:
Ready-to-use master mix for easy setup of reactions
Less reaction components to simplify bench work
Less magnetic beads used for cleanup procedures: This can reduce more than 50% of the beads consumption
Guaranteed high library conversion efficiency
Low input cell-free DNA: From 1 ng to 50 ng
Comparison of library conversion efficiency with different samples under the same condition.
Comparison of library yield with different samples under the same condition.
