ExSAR utilizes proprietary platform amide hydrogen/deuterium exchange mass spectrometry technology (H/D-Ex) to facilitate drug development and target validation. ExSAR’s H/D-Ex platform utilizes automated sample handling and proprietary software to generate rapid and reproducible measures of amide proton exchange rates. Typical applications involve drug binding interface determination and the detection of alterations in protein structure following protein/protein or protein/ligand complex formation. Other H/D-Ex applications focus on the detection of structure alterations in response to environmental modifications (e.g. new formulation, new buffer, etc.) or following genetic mutation (e.g. wild-type vs. inherited mutation).
