Hydrogen Deuterium Exchange (HDX)

Robust method for full structural characterization

Hydrogen deuterium exchange (HDX) mass spectrometry (MS) is a powerful tool for studying the dynamics of higher order structure of protein-based therapeutics. The rate of hydrogen-to-deuterium exchange within the amide hydrogen on the backbone of biotherapeutics provides solvent accessibility information and thus protein structure and conformation can be inferred. Orbitrap-based HDX MS using the Thermo Scientific Orbitrap Fusion Lumos Tribrid MS offers a robust method for the analysis of protein conformation, conformation dynamics, and protein-protein interactions.

Full structural characterization is critical in biopharmaceutical development where the subtle but critical local conformational changes can impact safety and efficacy.
