See beyond structure: HDX-MS for protein dynamics

Gain quantitative insights into solvent accessibility, backbone flexibility, and allosteric changes across proteins and protein complexes. Probe protein structure and conformational dynamics, and characterizing protein-protein and protein-ligand interactions under native-like conditions with hydrogen-deuterium exchange mass spectrometry (HDX-MS).

 

Uptake patterns can reveal conformational changes, map binding interface, and define dynamic regions that are invisible to static structural methods. By adding a dynamic perspective, HDX-MS data can guide and validate molecular dynamic (MD) simulations and complement structures from cryo-EM and X-ray.

 

Our mass spectrometers deliver high spectral quality for MS and MS/MS scans, supporting confident peptide identification and robust quantitation of deuterium incorporation. Together with integrated workflow solutions and advanced data analysis, HDX‑MS empowers scientists to build a comprehensive view of protein structure, motion, and interaction networks, effectively bridging the gap between protein structures and dynamics.
