Aggregation of proteins is a challenge commonly faced during the manufacturing of biopharmaceuticals. Tracking aggregation throughout the product’s lifecycle is a necessary regulatory requirement.

Our most recent addition, Wyatt’s DAWN 8 for SEC-MALS Analysis, determines the absolute molar masses of proteins, biopolymers and synthetic polymers, through multi-angle light scattering (MALS).

The combination of UV, Refractive Index and MALS detection provides an overall view of the aggregation profile of a molecule.
