Abstract: Dr. Glajch’s plenary lecture details the use of multi-angle light scattering detection (MALS) in combination with an optimized SEC separation to more adequately characterize a complex polymeric, polypeptide mixture, Glatiramer Acetate. A comparison to more standard techniques is provided to demonstrate the advantage of SEC-MALS for these measurements. In addition, the use of SEC-MALS to monitor the reactions is illustrated. This presentation also reports on the use of SEC-MALS to study the size of complexes formed between heparin and PF4, which ranged from less than 100 kDa to over 50 MDa.
