Ultraviolet (UV) laser photolysis of hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) for the <i>in situ</i> generation of hydroxyl radicals (<sup>•</sup>OH) is a widely utilized strategy in the oxidation footprinting of native proteins and mass spectrometry (MS)-based structural analysis. However, it remains challenging to realize peroxide-free photochemical oxidation footprinting. Herein, we describe the footprinting of native proteins by chloride-mediated peroxide-free photochemical oxidation o  ...[more]
