Characterizing Polymers and Polymer Aggregates Using
SEC-MALS and Batch-Mode MALS

Join us for a webinar on January 27, 8:00 AM PST | 11:00 AM EST | 17:00 CET

Multi-angle light scattering (MALS) remains a critical tool for characterization of polymers. In combination with separation by size-exclusion chromatography (SEC), MALS enables determination of molar mass distributions without relying on reference standards, making it invaluable for the analysis of polymers for which such standards do not exist, including novel homopolymers, block copolymers, and polymers with complex topologies. Beyond characterization of single macromolecules, batch-mode MALS can be used to analyze polymer assemblies that cannot survive fractionation conditions.

In this webinar we briefly review the theory and technology of MALS, then present specific applications in the characterization of homopolymers, block copolymers, lightly crosslinked polymers and polymer micelles.

Therapeutic Proteins in Biological Fluids:
Size Characterization Using AF4 with
Fluorescence and SPR Detection

Join us for a webinar on February 24, 8:00 AM PST | 11:00 AM EST | 17:00 CET

The analysis of aggregates of therapeutic proteins is crucial to ensure efficacy and patient safety. Typically, the analysis is performed in the finished formulation to ensure that aggregates are not present. An important question is, however, what happens to therapeutic proteins, with regard to oligomerization and aggregation, after they have been administrated intravenously.

This webinar features a demonstration of the separation of whole blood, plasma, and serum using asymmetric-flow field-flow fractionation (AF4) with a minimum of sample pre-treatment. The analysis of therapeutic antibodies in blood plasma using AF4 with fluorescence and surface plasmon resonance (SPR) detection is demonstrated in pre-clinical research with further potential for use in clinical trials, following implementation of appropriate quality systems. The results show the suitability and strength of AF4 for blood protein analysis and opens new important routes for the analysis and characterization of therapeutic proteins in blood.
