Emily Gaither, a bioprocessing engineer at Thermo Fisher Scientific, discussed a two-step polishing strategy for bispecific antibodies (bsAbs) in a GEN webinar. Bispecific antibodies can present purification challenges due to product-related variants that closely resemble the desired heterodimer. Gaither emphasized the importance of selecting appropriate chromatography resins and optimizing complementary unit operations for efficient process development.
The webinar showcased a systematic approach to screening polishing resins, tailored to the unique characteristics of bsAbs. Gaither compared various process configurations and evaluated purity, recovery, and process-performance tradeoffs to determine the most effective polishing train. She highlighted key takeaways, including strategies for matching resin selectivity to impurities, the impact of resin selection on process performance, and the balancing act between purity, yield, loading, and robustness.
The presentation concluded with a live Q&A session, allowing attendees to engage with Gaither and gain further insights into this crucial aspect of bsAbs manufacturing. This approach ensures effective and efficient process development, addressing the unique challenges posed by bispecific antibodies.
