Process Development And Intensification For Ultrafiltration/Diafiltration Of Viral Vectors

Fast, scalable viral vector manufacturing depends on efficient purification strategies early in the workflow. Optimizing the primary tangential flow filtration (TFF) step—through ultrafiltration and diafiltration (UF/DF)—can significantly streamline processing ahead of chromatography. Two distinct operating approaches, transmembrane pressure (TMP) and permeate control, offer different advantages depending on goals for process time, viral recovery, and impurity clearance. Comparing these strategies alongside the performance of widely used single-use TFF modules reveals practical considerations for balancing efficiency and product quality. Understanding how these variables interact provides a strong basis for refining process design, improving yields, and supporting reliable scale-up.

Explore how these insights can inform smarter development decisions and more consistent viral vector production outcomes.
