TFF-Easy – tangential flow filtration-based device
| Sample type: | Diluted EV containing matrices (i.e. urine, conditioned cell media) |
| Quantity: | 1 concentrator |
| Product overview: | 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). |
| Filter cartridge: | Polysulfone hollow fibres |
| Sample volume per reaction: | Recommended sample volume 5-15 ml. |
| EV recovery: | 83% |
| Concentration time: | 5 minutes |
| Reusable: | Up to 20 times |
| Application: | 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. |
