Exosomes
Purified extracellular vesicles, quantified and characterized lot by lot — from secretome to clinic.
COA per lotCell signaling, quantified.
Exosomes are 30–150 nm extracellular vesicles that carry proteins, lipids and regulatory RNA. 1CELL's exosomes are purified by tangential-flow ultrafiltration to minimize protein contamination.
Each lot is quantified by Nanoparticle Tracking Analysis (NTA) and confirmed by tetraspanin markers, with a lot-specific Certificate of Analysis.

Preserved as the product requires.
Storage conditions for exosomes depend on the formulation — some preparations are kept frozen, others refrigerated. 1CELL confirms the conditions with the source laboratory for each lot and coordinates packaging, transport and clinic handoff.

What the research says.
Research is exploring the role of exosomes in cell-to-cell signaling and tissue repair. Most data are preclinical, and product composition varies by source and process. International guidelines (MISEV) define how they should be characterized.
Exosome products are not approved as therapies in many jurisdictions, including the United States.

Exosome questions.
What does "10¹⁰–10¹² particles" mean?
It is the range of vesicles per vial measured by NTA. The exact value for each lot appears on its Certificate of Analysis.
Who can order exosomes?
Licensed physicians and clinics, where permitted by local regulation. Request professional access and we will verify your credentials.
How are they shipped?
Frozen or refrigerated, depending on formulation, with temperature monitoring and a custody record.
Are exosomes approved?
They are not approved as therapies in many jurisdictions, including the United States. Use is the treating physician's decision within applicable regulation.
