Abstract
Although size exclusion chromatography (SEC) has been, and will continue to be, the primary analytical tool for characterization of the content and size distribution of non-particulate aggregates in protein pharmaceuticals, regulatory concerns are driving increased use of alternative and complementary methods such as analytical ultracentrifugation and light scattering techniques. This review will highlight and critically review the capabilities, advantages, and drawbacks of SEC, analytical ultracentrifugation, and light scattering methods for characterizing aggregates with sizes below about 0.3 microns. The physical principles of the biophysical methods are briefly described and examples of data for real samples and how that data is interpreted are given to help clarify capabilities and weaknesses.
Keywords: Aggregate, analytical ultracentrifugation, light scattering, sedimentation velocity, size exclusion chromatography, oligomer

Artificial Intelligence in Bioinformatics
Bioinformatics is an interdisciplinary field that analyzes and explores biological data. This field combines biology and information system. Artificial Intelligence (AI) has attracted great attention as it tries to replicate human intelligence. It has become common technology for analyzing and solving complex data and problems and encompasses sub-fields of machine ...read more
