WebJun 15, 2014 · In HDX-MS, the standard protocol relies on a proteolytic digestion of the deuterated protein followed by mass measurement of the peptide fragments, which is usually done in an ESI(-LC)-MS strategy [8], but can also be done by MALDI-MS [9], [10], [11]. The ability to localize the individual deuterated residues (the spatial resolution) is … WebHydrogen/deuterium exchange (HDX) monitored by mass spectrometry (HDX-MS) has become a valuable tool in studies of protein dynamics and protein interactions. Isotopic exchange is typically initiated by diluting a protein solution into deuterated buffer at physiological conditions. H–D exchange was measured originally by the father of hydrogen exchange Kaj Ulrik Linderstrøm-Lang using density gradient tubes. In modern times, H–D exchange has primarily been monitored by the methods: NMR spectroscopy, mass spectrometry and neutron crystallography. Each of these methods have their advantages and drawbacks. crystal reports date to text
