BSA Monomer-Dimer Elucidation with the BI-MwA

Aggregation kills. Aggregated therapeutic proteins can provoke immune response and have reduced therapeutic effect. This has led to regulatory and industrial interest in identifying aggregates for elimination. Size-exclusion chromatography (SEC/GPC) has been a useful technique for the determination of molecular weights of proteins. However, its usefulness is limited by the requirement for calibration of the […]
