WebMay 22, 2024 · Ion mobility-mass spectrometry can be used to map the energy landscape of the collision-induced unfolding of antibodies (shown) and other proteins. Such maps can provide a fingerprint to characterize biotherapeutics. In another protein-related application, researchers use IMS-MS to monitor collision-induced unfolding (CIU) of antibodies. WebDec 13, 2024 · Strong orthogonality to mass spectrometry makes differential ion mobility spectrometry (FAIMS) a powerful tool for isomer separations. However, high FAIMS resolution has been achieved overall only with buffers rich in He or H2.
