Downstream Processing for Cell-Based Therapies
However, this technique, although suitable for the purposes of the study, is not a scalable technique like TFF. Other groups have used TFF and expanded-bed chromatography (EBC) as continuous, integrat…

Exosome isolation by tangential flow filtration and size exclusion chromatography
We found that:
- Cytiva™ superSEC resin enriched exosomes from impurities compared to legacy Sepharose™ CL-2B resin—a well-established resin for exosome purification—after the initial TFF step.

Single-Use for Downstream Chromatography: Benefit or Hindrance?
As Young points out, reusable systems can typically require more than 12 hours from set-up to tear-down, while single-use TFF systems require half that time.
Another area where single-use is gainin…

Process Chromatography: Continuous Optimization
A salt-tolerant resin can be very beneficial to a purification process by decreasing the need for dilution or eliminating TFF steps all together,” she notes.
“Next-generation IEX resins that offer…

Unifying Continuous Biomanufacturing Operations
…angential-flow filtration (TFF), comments Morbidelli, although he says the scale-up for both ATF and TFF remains, to a certain extent, an open issue. Bonham-Carter notes that using ATF for cell reten…

Downstream Processing Continues to Worry CMOs
Indeed, a majority of CMOs are considering using single-use disposable TFF membranes and single use-prepacked columns. It remains to be seen the extent to which these will help. Downstream continues t…
