Cell Culture Media Exosome Purification Kits

Features and Benefits

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 5 mL to 35 mL
- Cell Culture Media Exosome Purification Mini Kit (5 mL - 10 mL)
- Cell Culture Media Exosome Purification Maxi Kit (20 mL - 35 mL)
Exosome purification is based on Norgen’s proprietary resin
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 other 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 another RNA extraction method.

The Cell Culture Media Exosome Purification Kits provide a fast, reliable and convenient method to purify and enrich for intact exosomes from different cell culture media sample volumes ranging from 5 mL to 35 mL. These kits also allow for the purification of intact extracellular vesicles (EVs) from different cell culture media sample volumes, and these EVs are ready for most downstream applications. 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 Cell Culture Media 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 Cell culture media 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.

Supporting Data

Figure 1. Isolation of RNA from exosomes purified from different cell culture media volumes. Norgen's Cell Culture Media Exosome Purification Mini Kit (Cat. 60400) was used to isolate exosomal RNA from exosomes purified from different cell culture media volumes using the same kit. 2 µL of the isolated RNA was then used as the template in RT-qPCR reactions to assess the amplification of the isolated exosomal RNA (A) The exosomal avg. Ct value for miR-26a is linearly decreasing with increasing the sample input volume. (B) The relative amount of the exosomal miR-26a shows excellent linearity with a percentage of recovery of more than 90%

Figure 2. Isolation of RNA from exosomes purified from different cell culture media volumes. Norgen's Cell Culture Media Exosome Purification Maxi Kit (Cat. 60600) was used to isolate exosomal RNA from different cell culture media volumes from exosomes purified using the same kit. 2 µL of the isolated RNA was then used as the template in RT-qPCR reactions to assess the amplification of the isolated exosomal RNA. (A) The avg. Ct value for exosomal miR-26a is linearly decreasing with increasing the sample input volume. (B) The relative amount of the exosomal miR-26a shows excellent linearity with a percentage of recovery of more than 90%.
