PureExo® Exosome Isolation kit (for stem cell culture media)

Why our exosome so pure?
Answer: By targeted filtration, our filter of specific binding treatment removes protein contaminant to isolate exosome at 95% high purity.        Click to see pure exosome images

Isolate pure exosome from stem cell culture media (supernatant). This kit yields much higher purity than exosome precipitation method. This product is for research use only.


Each reaction can process 20 mL stem cell culture medium. The yield of each reaction can yield pure exosome suspended in 50 ~ 200 µL PBS .


P107 kit is for exosome purification / isolation at high yield and purity from stem cell culture media.

  • Easy to use: No ultra-centrifugation (< 2 hours)
  • 10 fold higher yield (vs. other kits and ultracentrifuge)
  • Save cost (vs. antibodies-beads method)
  • Isolate Pure exosome (>95% purity vs. 25% purity by exosome precipitation method)
  • Intact exosome (good morphology)

This kit isolate high yield pure exosomes for any downstream applications: EM study, exosome label, exosome subpopulation, qRT-PCR profiling of exosomal miRNAs, and gel analysis of exosomal proteins.
