Interlaced size exclusion liquid chromatography of monoclonal antibodies.

Size exclusion chromatography is a widely performed analysis of monoclonal antibodies, primarily used to monitor the levels of higher weight molecular species such as aggregates. Owing to the subtleties of these separation mechanisms and frequently observed partial resolutions of components in these separations, many common methods for increasing the method throughput are not practical as they trade off resolution for speed. Short columns, high flow rates and smaller particles are examples of these approaches.
