Characterization of Self-Associating Antibody Solutions at High Concentrations with CG-MALS

This application note describes the use of multi-angle light scattering (MALS) for characterizing the intermolecular interactions between three different high concentration antibody solutions using a Calypso II, a HELEOS II MALS detector, and Optilab T-rEX™ dRI detector. CG-MALS measurements, automated by Wyatt equipment, provided insight into the colloidal behaviors of the antibody solutions and the nature of the intermolecular forces that contribute to high viscosity.
