Mass Spectrometric Analysis of Intact Human Monoclonal …
Aggregation is a common degradation process for therapeutic proteins and can occur during production, formulation and storage, e.g. due to pH changes, temperature variations and agitation (6–8). Partial unfolding or other types of conformational changes in the protein structure may cause aggregate formation (9–12).
