Improving mAbs Impurity Clearance Through Use of Selective Additives (Feb 2023)

Developing more effective chromatography resins for mAbs downstream processing is important ⏤ but it's not the only way to improve impurity clearance. In this study of the use of additives to enhance resin performance, two mAbs chromatography resins were examined. Both were used for a capture step, and additives were screened to reduce the nonspecific binding of impurities. The goal of the study was to optimize chromatography steps and thus increase the capacity and removal of impurities.
