Traveling wave ion-mobility mass spectrometry (TWIMS) combined with native mass spectrometry (MS) has emerged as a powerful tool for analyzing biomolecules, including complexes of protein and heparan sulfate (HS). This technique allows determination of the stoichiometry of the protein-HS interaction and information on the overall 3D molecular envelope.
