Downstream Process Intensification with Novel Chromatography Resins for Enhanced Monoclonal Antibody Purification
In this presentation, we will demonstrate an integrated mAbs downstream purification process to enable significant throughput improvement while removing of critical impurities. The process approach includes (1) pre-absorption filtration technology and (2) buffer additives. Through use of pre-absorption filtration technology, in combination with PROchievA protein A affinity resin, that possess high dynamic binding capacities of greater than 60 g/L, we have obtained antibodies with increased purity, while reducing overall process time. Furthermore, by using select additives during process chromatography, we demonstrate this process can be 'fine tuned' to enhance target antibody selectivity by removing host cell protein impurities and aggregates. When used in conjunction, these technologies represent a highly efficient process to obtain monoclonal antibodies for use as therapeutics.
