Research Interests:

Association and aggregation play an important role in development of pharmaceutical peptide formulations. A detailed understanding about solvent dependent changes in the association state is an essential tool. These information are relevant for development of stable storage formulations or predictions of the peptide behavior after patient treatment. To analyze peptide association and peptide interactions we combine several hydrodynamic and spectroscopic methods, e.g. static (SLS) and dynamic (DLS) light scattering, circular dichroism spectroscopy and fluorescence spectroscopy.

For example in SLS and DLS experiments we analyze the scattering of laser light by peptide solutions. The mean scattering intensity of the peptide solutions relative to a scattering standard solution is used to determine the molecular mass of the peptide in solution (SLS). In contrast, from the time dependent fluctuation of the scattering signal the diffusion coefficient of the peptide can be calculated (DLS). Combining both methods changes in the peptide association state can be analyzed, e.g. during aggregation.
