Webinar Description:

Optimizing Protein Biotherapeutic Formulations with the Light Scattering Toolkit. Biophysical techniques based on static and dynamic light scattering address many of the key analytical challenges in biotherapeutic formulation development, including screening for aggregation, colloidal and conformational stability, viscosity and chemical modifications. This seminar will review light scattering technology and instrumentation, then present select examples illustrating how complete light scattering solutions facilitate rapid and effective development of protein-based biotherapeutic formulations.

Learning Objective Bullet Points:

• The light scattering technologies and instrumentation relevant to protein biotherapeutic formulation
• How a dynamic light scattering (DLS) plate reader is used to pre-screen dozens of formulations for aggregation, propensity for aggregation and viscosity
• How multi-angle light scattering couples to HPLC- or UHPLC-based size-exclusion chromatography (SEC-MALS) and field-flow fractionation (FFF-MALS) to characterize soluble and insoluble aggregates, as well as fragments and other degradation products
• How composition-gradient multi-angle light scattering (CG-MALS) characterizes reversible self-association and co-solute interactions
• How automated electrophoretic light scattering (MP-PALS) characterizes pI and zeta potential of proteins, directly in formulation buffer.
