Developing a toolkit towards prediction of protein aggregation

Webinar Description:

PIPPI, which stands for Protein-excipient Interactions and Protein-Protein Interactions, is a European academic-industrial consortium addressing the challenges in formulation of protein-based drugs. Its overall objective is to develop methodologies, tools and databases to guide the rational formulation of robust protein-based therapeutics. In this webinar we will present much of the effort carried out under the PIPPI program.

Machine learning: Due to the overwhelming amount of data available from high-throughput techniques such as plate-based DLS, there is a staggering increase in opportunities for finding patterns in data. Such patterns are helpful to predict long-term stability of therapeutic proteins. The application developed to identify those patterns by artificial neural network is shown.

Self-association: An in-depth case study regarding the nature of the native self-association of a full-length IgG1, as well as the corresponding Fab and Fc fragments, is presented. The case study includes comprehensive investigations by SEC-MALS, DLS, SLS, AUC, SAXS, AF4-MALS and intrinsic fluorescence.

RP-MALS: Finally, the benefits of coupling ultra-high-pressure reverse-phase liquid chromatography (UHPLC-RP) with a low-dispersion MALS detector, for the characterization of intact monoclonal antibody (mAbs) and their fragments, are shown.

Key Learning Objectives:

  • Gain exposure to research into machine learning for prediction of aggregation
  • Understand the benefits of MALS detection for reverse phase chromatography
  • Become acquainted with extensive formulation screening methodology developed in the context of the PIPPI program
  • Gain understanding of native reversible self-association and its analytical challenges

Who Should Attend:

  • Product Managers for protein-based biotherapeutics
  • Formulation scientists
  • Lab managers responsible for protein formulation analytics and/or data mining
