It provides expert reviews of the state-of-the art for the range of analytical methods used for assessment of protein aggregates and the numerous challenges that are unique to each method. Furthermore, the book provides insight into the future of method development and regulatory issues for protein aggregates. With comprehensive coverage of the key issues, this book will be a critical reference for the field for many years. REFERENCES 7 REFERENCES 1. Rosenberg AS. Effects of protein aggregates: an immunologic perspective.

The common analytical methods for the analysis of protein aggregates include SEC, analytical ultracentrifugation (AUC), field-flow fractionation (FFF), and gel electrophoresis. These methods involve partial or complete separation of the different species and are mainly used to measure the levels of protein aggregates and determine their sizes. Recently, the AUC with a fluorescence detection system (FDS) has also shown promise to measure protein self-association at high concentration directly in formulation buffer or human serum.

Although there is no physical separation of protein species in centrifuge cells during sedimentation equilibrium experiments, sedimentation equilibrium and velocity methods are closely related. Thus, we include the discussion of both methods in this chapter. The sedimentation velocity experiment is usually conducted at relatively high rotor speeds and the centrifuge run only takes a few hours to complete. Each protein species can form a unique boundary and sediment at a characteristic speed under a specified centrifugal force on the basis of its molecular mass and shape.
