Event Overview:

The Intabio ZT system integrates imaged capillary isoelectric focusing (icIEF) with UV detection and mass spectrometry (MS) to rapidly separate, quantify, and identify biopharmaceutical charge variants in a single workflow. This capability makes it a powerful tool for gaining high-resolution insights into protein structure, function, and stability—from early cell line development through formulation.
In this webinar, learn how your biopharma peers are applying icIEF-UV/MS with the Intabio ZT system to strengthen analytical strategies and accelerate decision-making. Topics include:

  • Charge variant analysis via icIEF-UV/MS: See how this integrated technique provides detailed structure-function insight for complex molecules such as Fc fusion proteins.
  • Stability assessment through forced degradation: Explore how intact and subunit icIEF-UV/MS workflows can reveal key stability profiles and support robust formulation development.

Join this session to discover practical, data-driven approaches for addressing the analytical challenges of modern protein therapeutics.


Key Learning Objectives:

  • Learn how to facilitate in-depth characterization of highly glycosylated and sialylated fusion proteins.
  • Discover how to develop a platform method for charge heterogeneity characterization of complex therapeutics.
  • See how to achieve rapid assessments of stability in forced degradation studies.

Who Should Attend:

  • Analytical scientists in Biopharma
  • Process development scientists
  • Researchers with roles in the development of next-generation biologics

Speakers

Anita Liu is an Associate Principal Scientist in the Biologics Mass Spectrometry (MS) group at Merck & Co., focusing on MS-based method development and technological innovation to advance biotherapeutic characterization. She earned a BS in Chemical Engineering from Princeton University and an MS in Chemical Engineering from Cornell University.
Anita began her career in mass spectrometry at ExSAR, where she applied hydrogen-deuterium exchange MS (HDX-MS) to higher-order structure analysis of antibody drugs. She then joined Regeneron Pharmaceuticals, leading the development of anion-exchange chromatography–MS (AEX-MS) for charge variant analysis in monoclonal antibodies and hydrophilic-interaction chromatography–MS (HILIC-MS) to assess quality attributes in adeno-associated virus capsids. At Merck, she continues to explore innovative MS approaches, including the coupling of imaged capillary isoelectric focusing with UV and MS detection (icIEF-UV/MS).


Anita has over 15 years of industry experience in MS-based protein characterization and separation science.
