In Silico Reagent Design for Electron-Transfer Dissociation on a Q-TOF

Journal of the American Society for Mass Spectrometry, 2021
Electron-transfer dissociation is an important technique capable of probing the primary and higher order structure of a wide variety of biomolecules and yielding information that is often inaccessible using other common MS methods. The source of the electron used to initiate the fragmentation event is a radical anion, and the fragmentation process ...
