Exosome   vs   Endosome Isolation Kit
We also offer purified exosome:


Isolate pure exosome from 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 2 ~ 4 ml cell culture medium. The yield of each reaction can yield pure exosome suspended in 50 ~ 200 µl PBS (from which 150 ~ 400 µg exosomal protein or 50 ~ 200 ng exosomal RNA can be extracted using our Exosomal RNA and Protein Extraction Kit, Cat.#: P200).


P100 kit is for exosome purification / isolation at high yield and purity from cell culture media.

  • Easy to use: No ultra-centrifugation (< 2="">
  • 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)

Use as little as 2 ml cell media to achieve high yield of exosomes for any downstream applications: EM study, exosome label, exosome subpopulation, qRT-PCR profiling of exosomal miRNAs, and gel analysis of exosomal proteins.

Shipping / Storage

Ship and store at room temperature. Upon receiving keep all bottles upright, in cool and dark place.

Because the exosome yield of this exosome isolation kit is 10 fold higher than all other kits, you can start with only 2 mL medium. The maximum medium volume of each reaction is 4 ml from at most 5 x 105 cells. One PureExo® Column is only for one reaction. Do not exceed 4 mL medium or 5 x 105 cells to avoid indistinct layer separation and column clogging.
