Identification of Protein Aggregation Through UV-Visible Spectroscopy

Protein aggregates can irreversibly form in solution through a number of processes and are common within unstable samples. This results in a lower concentration of non-aggregated materials which can negatively impact pharmaceutical applications and can require further purification steps. Therefore, it is important to determine the extent to which a sample is aggregated early in the experiment. Typically, aggregates are identified using size exclusion chromatography. However, recovering the samples after this analysis is difficult and often time-consuming.
