Theodor (Thé) Svedberg invented the analytical ultracentrifugation (AUC) method in the 1920s, and it has now become a versatile biophysical method commonly used for in vitro analysis of proteins, nucleic acids and their complexes. Analytical ultracentrifuge is an integration of ultracentrifuge and optical detection system, which can detect the evolution of particle concentration distribution after centrifugation in real time. analytical ultracentrifugation https://www.iaanalysis.com/analytical-ultracentrifugation-auc-platform.html
