Biopharmaceutical production often involves multi-step chromatog.-based processes using resins of suboptimal cleaning-in-place stability, flow properties, and (< 100 g/L) dynamic binding capacity (DBC).This is particularly true for Protein A based affinity resins.Research has led to improved resin flow characteristics (particle and pore size homogeneity and mech. rigidity), chem. stability, and enhanced DBC which is apparent for resins such as Amsphere A3.However, recent improvements in affinity and non-affinity resins tend to be incremental, not revolutionary.A key reason for this is that the column format demands resin design focus on mech. rigidity and pressure-flow characteristics.Modular, stackable, and bed-supported chromatog. devices such as ChromNeX greatly reduce the above constraints, often increasing acceptable linear velocity allowing improved performance from legacy resins, performance focus design and use of new resins.This study showcases the performance of a newly designed Protein A resin, specifically optimized for the ChromNeX platform.This resin demonstrates a remarkable increase in productivity as compared to Amsphere A3.Presently, biopharmaceutical companies and suppliers are investigating diverse techniques to achieve higher productivity, such as utilizing multi-column continuous systems, employing short-bed-height columns with rapid cycling and variable load flow rates to enhance resin capacity, and considering non-resin technologies like membranes, which have been presented and discussed.In this study, we will conduct comparison between ChromNeX technol. and select alternative approaches.By evaluating and contrasting the advantages and disadvantages of the methodol., we aim to provide insights into their resp. capabilities for achieving high productivity and improving this unit operations for biologics manufacturing
