A compelling method for isolating exosomes: size exclusion chromatography (SEC)

Exo-spin™ SEC columns can be used as a stand-alone product or as part of a combined strategy for isolating small EVs!

CellGS offers pre-packed and equilibrated ready-to-use SEC columns!

With the pore size of the resin being approximately 30 nm, Exo-spin™ SEC columns offer a highly pure exosome elution ready for any downstream application.


Exosomes elute first and are followed by non-EV components
