Over the past decade, single-use tangential flow filtration (TFF)
technologies have emerged to reduce system preparation time, promote
fast and flexible product change over, and ultimately shorten process
development and manufacturing time/cost. In this study, the performance
of a recently developed Pellicon® single-use TFF capsule was compared
against traditional Pellicon® cassette by assessing TFF process
performance (such as flux, residuals clearance, and yield) and
post-purification product attributes (such as concentration and
mass-weighted average molecular weight). Good scaling was shown by
comparing process performance and product attributes across different
scales and formats. Additionally, similar TFF process performance and
post-purification product attributes were observed for the single-use
capsule compared to the reusable TFF cassettes. The capsule requires a
smaller flush than the cassette, and it is easier to use since it does
not require a compression holder or pre-sanitization. The results
provide insight into the application of the single-use TFF capsule and
scalability of TFF processes for the purification of conjugate vaccines.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
