Human Exosome, purified from normal human serum

Cat. #



Normal human exosome can be used as:
  • Standard exosome control
  • To study human exosome activity

Using our PureExo filtration method, the purified exosome does not contain any polymer or detergent (SDS, NP-40 or trition), so it is safe for mass spectrometry.

This product is for research use only.


The 2013 Nobel Prize in Physiology or Medicine was awarded to the discovery of cell vesicle transportation.   This elucidates the importance of vesicles, including exosome, in cellular communication and their potential use in diagnostics and therapy.

Exosome is nano-sized (30 ~ 200nm) vesicles secreted by cells that play important role in intercellular communication and cell signaling. Exosome contains specific RNA transcripts, including shuttle RNA, mainly mRNA and microRNA, which are thought to be involved in this cell-cell communication.  Exosome naturally transports these RNAs between cells.  It potentially carrying as disease signals (transcripts) that can be used as biomarkers.  These exosome might also be useful in gene cancer therapy to deliver therapeutic short interfering RNA (siRNA) to the target cells.

Exosome is now believed to be present in all body fluids, especially serum/plasma, urine, cerebrospinal fluid (CSF) and saliva.  This product is pure exosome isolated from normal human serum using our PureExo kit.  The purity is warranted.
