Evaluation of Poros AAVX Pan-Affinity Resin for rAAV purification and cGMP ManufacturingPublished: January 14, 2019
Affinity interaction based resins are the foundation for the platform purification of many different biological molecules. While some AAV affinity resins have existed for more than a decade, the growth in the AAV field now demands a true pan-affinity workhorse, analogous to Protein A for mAbs. In this work, Daniel Hurwit, Voyager Therapeutics, investigates POROS CaptureSelect AAVX (AAVX) for the purification of various serotypes from both crude and pure feed streams. Performance of AAVX is directly compared against other commercially available AAV affinity resins for qualities such as binding capacities, binding kinetics, product recovery, impurity clearance, washing and elution strategies, cleanability, cyclability, regeneration as well as the scalability and suitability of the new resin for commercial manufacturing. The results demonstrate that the new AAVX resin is a robust option for the scalable, platform purification of various rAAV capsids from crude feed streams.
