Stabilizing proteins by chemical cross-linking: Insights into conformation, unfolding, and aggregation using native ion mobility mass spectrometry

Our group attended the Polish Peptide Symposium with great talks and posters. Thanks to the organisers for the exciting event! Congratulations to Felix Paulußen for winning the Award for the Best Poster Presentation.

After nearly a decade at the Vrije Universiteit Amsterdam, Tom is starting a new position at the University of Göttingen. A big THANK YOU to everyone in the group who supported our research and teaching activities throughout the years!!

Big congrats to Juan for being awarded a Marie Skłodowska-Curie postdoc fellowship by the European Union! It is great to have Juan pursue his work on the design of proteomimetic scaffolds with enhanced biological function, such as inhibitors for the oncogene β-catenin.

Health~Holland supports our initiative of modulating Galectins using INCYPRO (LSHM24021) via a Public-Private Partnership Allowance. We’re looking forward to work together with Dr. Victor Thijssen (Amsterdam UMC) and the Incircular team.

We wish everyone a Happy New Year!! Also, all the best to Alejandro Yeste-Vázquez who’s leaving our group to join the lab of Juan Del Valle at the University of Notre Dame.

Congratulations to Felix Paulussen for securing funding by Biotech Booster a Nationaal Groeifonds for developing cancer treatments based on the group’s findings: Yeste-Vázquez et al. Angew Chem 2024 and Wendt et al. Angew Chem 2021.
Big thanks to our technology transfer office IXA for their support!
