- Abstract
We propose a new method to measure the viscosity of concentrated protein solutions in a high-throughput format. This method measures the apparent hydrodynamic radius of polystyrene beads with known sizes using a dynamic light scattering (DLS) system with a microplate reader. Glycerol solution viscosities obtained by the DLS method were in good agreement with those reported in the literature. Viscosity of the solutions of two monoclonal antibody molecules was acquired using both DLS and cone-and-plate techniques, and the results were comparable. The DLS method described here has the potential to be used in many aspects of protein characterization., (Copyright 2009 Elsevier Inc. All rights reserved.)
