Peptide Aggregation – a complex topic

Aggregation is a complex and heterogenous process for peptides. The individual trigger for peptide aggregation is peptide specific and can be induced by standard manufacturing conditions​. Therefore, it is important to evaluate and manage the manufacturing process to produce physically stable drug substances. Our experts share their analytical expertise on peptide aggregation and how to avoid it through optimized downstream process conditions.

About the Speakers

Dr. Patrik Plattner

Senior Group Leader QC

Patrik Plattner is a Senior Group Leader in the quality control department at Bachem’s main site in Bubendorf, Switzerland. His work covers various analytical techniques with a focus on spectrometric and spectroscopic techniques for the investigation of the peptides regarding their chemical and physical stability. In addition, he and his team are responsible for method validation, implementation of the techniques in routine tests and support of control strategies at the frontier of peptide analysis. Patrik received his PhD in chemistry from the University of Bielefeld, where he worked in the group of Prof. N. Sewald with a broad focus from chemical synthesis up to bioanalytic of peptidomimetics. He joined Bachem as an analytical scientist in 2010.

Dr. Ho-Wah Siu

Scientist QC

Ho-Wah Siu, a scientist for aggregation analytics in the Quality Control Department at Bachem in Switzerland, works on method development to study the aggregation kinetics of active pharmaceutical ingredients (APIs) with various spectroscopic and chromatographic techniques. Ho-Wah obtained his PhD in chemistry from the University of Konstanz in the group of Prof. Karin Hauser. There he used various spectroscopical techniques to investigate the dynamics of secondary structural elements of model peptides. Of particular interest in these studies were the initial steps of aggregation of polyQ-rich peptides associated with neurodegenerative diseases.
