Webinar: Physicochemical Characterization of Antibody-Drug Conjugates

April 8, 2021


  • Analysis of the higher order structure (HOS) of therapeutic antibodies and antibody drug conjugates.
  • Study of the effects in secondary structure of conjugated proteins.
  • How the AQS³pro, with Microfluidic Modulation Spectroscopy, provides reliability, increased sensitivity and higher resolution for secondary structure analysis of biotherapeutics.
  • Considerations of the physicochemical properties of ADCs and other proteins


Antibodies are the most rapidly growing form of therapeutic. High-throughput methods of characterization are essential as companies and researchers move to develop new candidates. In this webinar, Dr. Shawn Owen discusses advanced characterization techniques to assess biophysical properties of antibody-drug conjugates (ADCs). For ADCs, the level of payload and site of conjugation are determined using LC/MS. Thermal stability and binding affinity are characterized using DSC, IR, and ITC. These methods, along with MMS, can be used for the in-depth analysis of these biologics, to analyze physicochemical properties, and for routine product validation.

Senior Field Application Scientist, RedShiftBio

Dr. Jason Lin is a Senior Field Application Scientist at RedShiftBio. At RedShiftBio, Jason utilizes Microfluid Modulation Spectroscopy to characterize changes in higher order structure in proteins, antibodies, peptides, and virus due to chemical and thermal stressing. Prior to joining RedShiftBio, Jason was a field Application Scientist for Wyatt Technology. At Wyatt Technology, Jason utilized dynamic, static, and electrostatic light scattering techniques to characterize the size, mass, and interaction of proteins, nanoparticles, polymers, polysaccharides, and AAVs. Prior to joining Wyatt Technology, Jason obtained his Ph.D. at the University of California, Santa Barbara (UCSB). At UCSB, Jason utilized fluorescence, ellipsometry, and atomic force microscopy to investigate how morphology impacts the diffusion length of excitons in organic solar cells.
