Abstract

The inventors discovered that viscosity of a protein solution can be estimated by measuring the apparent particle size or apparent molecular weight by a small angle X-ray scattering (SAXS) method or X-ray solution scattering method, which enables measurement of small amounts of samples, and then correlating those measurement results with viscosity of the protein solution.
