Custom freeze dried EVs
In addition to offering off-the-shelf freeze-dried exosomes, Cell Guidance Systems produces exosomes from other cell lines provided by researchers. Freeze drying is a process whereby volatile molecules such as water or other solvents are removed from non-volatile material using a vacuum.
Samples are kept frozen during the process so the water molecules are primarily removed by sublimation (solid-to-gas transition) rather than evaporation (liquid-to-gas transition). Freeze drying retains the structure of the non-volatile material which can better retain bioactivity. For example, exosomes that have been subjected to freeze-drying retain therapeutic bioactivity.
Cell Guidance Systems uses freeze drying as part of our production process for exosomes (please see an example of our freeze-dried exosome products here) and for other products. Based on our years of experience, we offer a cost-effective freeze-drying service for research use only.
