Pdf Protein Concentration And Diafiltration By Tangential Flow Filtration Semantic Scholar Presentation1 Tff. In ultrafiltration UF tangential flow filtration TFF systems operating parameter selection will have far reaching impact as the process is scaled to full-scale manufacturing levels. 1 INSTALLcassette with torque wrench.
In Tangential Flow Filtration TFF the fluid is pumped tangentially along the surface of the membrane. In contrast to standard tangential flow filtration equipment TFF the cross-flow is accomplished by movement of the filter. Cross-flow filtration CFF or tangential flow filtration TFF has proven as suitable downstream processing operation for virus and VLP processing Carvalho et al 2019.
This process is done by selecting a filter significantly smaller than the solute molecules to allow for a higher retention of solute molecules. Diafiltration DF is most often used to exchange product into a desired buffer eg from an elution buffer into a final formulation buffer UF and DF typically use tangential flow filtration where feed flows parallel to the membrane surface rather than perpendicular to the surface. This technical brief is a practical introduction to protein processing using tangential flow filtration.
