A critical review of methods for size characterization of non-particulate protein aggregates

Philo, John·2009·Current Pharmaceutical Biotechnology

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.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
