TFF-Easy – tangential flow filtration-based device
Diluted EV containing matrices (i.e. urine, conditioned cell media)
TFF-Easy is used for concentration and desalting of sample solutions, and is emerging as a new technique for EV isolation if coupled with SEC (Pure-EVs columns).
Polysulfone hollow fibres
Sample volume per reaction:
Recommended sample volume 5-15 ml.
Up to 20 times
Concentration of diluted matrices such as cell media or urine prior to EV isolation.
Easy removal of small molecules and ions from the EV preparation.
EV dialysis for changing buffer conditions.
High efficiency of EV isolation if coupled with SEC columns.
