🔍 Scottish researchers evaluated 44 polishing chromatography elution strategies to maximize mAb recovery yield and titer.
🔬 Only nine strategies achieved the target yield and titer, with seven-stage ultrafiltration systems performing the best.
💡 Integrating ultrafilters with chromatography columns can produce high concentration yields and prevent mAb dilution.
💰 Step elutions use less salt than gradient elutions, leading to potential cost savings for manufacturers.
⚠️ Regardless of the elution method, achieving a sharp peak and reaching the yield target is crucial.

📢 Boost mAb Production: Top Strategies Revealed!
Introduction:
This article discusses a recent study conducted by Scottish researchers that evaluated different separation systems for monoclonal antibody (mAb) manufacturing. The study aimed to reduce variability and maximize recovery yield and mAb titers during downstream purification.
Main points:
- The researchers evaluated 44 polishing chromatography elution strategies based on yield and titer.
- Only nine strategies achieved the target yield and titer, and four achieved the targeted pH range.
- Seven-stage ultrafiltration systems outperformed three-stage configurations.
- Purest elutions occurred at pH 6.1 due to changes in protein resin affinities.
- Integrating ultrafilters with polishing chromatography columns can increase concentration yields and allow for increased pressure drop.
Conclusion:
The study highlights the importance of selecting the appropriate separation systems for mAb manufacturing to maximize yield and titer while minimizing variability. Integration of ultrafilters with polishing chromatography can significantly improve concentration yields and optimize purification processes.
