In biopharmaceuticals, dimers in peptide-protein aggregats are strictly regulated by size exclusion chromatography. However, protein aggregates of 0.1 µm to 10 µm are not regulated. This presents a crucial problem in light of the imunogenicity risk of proteins.

We measured the particle diameters of proteins using dynamic light scattering.
