Biological Macromolecules: Exploring Analytical Development and QC Case Studies in Antibody Developability and Biologics CMC

  • Wednesday, October 19, 2022

Biological macromolecules (monoclonal antibodies, recombinant proteins, fusion proteins, antibody-drug-conjugates, polypeptides and vaccines, etc.) are powerful therapeutics, and their characterization has drawn considerable attention and urgency in the biopharmaceutical industry. A developability assessment at an early stage can provide a better understanding of candidates, deliver better and safer therapeutic candidates and reduce risk during late-stage development.

In this webinar, the featured speakers will review:

  • Antibody quality attributes that are critical to development and traditional and state-of-the-art analytical methods to monitor those attributes
  • A practical workflow for developability assessment, including in silico evaluation, extended characterization and preliminary stability studies using appropriate analytical methods
  • Case studies on conducting developability assessment experiments


Unlike small-molecule drugs (150–600 Da) that have rigid structures, macromolecules undergo complicated folding and can exist in several low-energy structures, posing a challenge for traditional methods in structural biology. The complete analysis and appropriate characterization of macromolecules are important to their safety, purity, potency, stability and overall quality. This webinar reviews the methodologies that are used to characterize important attributes of biopharmaceutical proteins.

Biophysical characterization is critical to understanding details of the structure-function relationship of biological macromolecules. Microcalorimetry techniques are powerful tools for in-depth characterization of molecular binding events and structural stability. These techniques generate comprehensive thermodynamic profiles for protein domain structures and the energetics of inter- and intra-molecular binding events. In addition, they help determine stability and affinity. Mass spectrometry has widely been used as a tool for identification of proteins because it can provide accurate information on molecular masses of biological molecules with a small amount of sample in a short time. Also, it can give information on the tertiary structure or on the molecular interactions of biological macromolecules.

The speakers will discuss relevant analytical methods, including techniques (SPR, BLI, DSC, DLS, CD, LC-MS/MS, etc.) to determine thermal stability, activity, protein sequence, post-translational modifications, degradation, glycosylation, folding, disulfide bond shuffling and aggregation. An aberrant result for these attributes may raise quality issues.
