The Gas-Phase Oxidation of Cationic Bioanalytes via Ion/Ion Reactions
Several solution-phase derivatizations have recently been implemented in the gas-phase through the interaction between oppositely charged ions, viz., ion/ion reactions. The work presented here primarily focuses on the oxidation of bioanalytes via ion/ion reactions with periodate and persulfate …

Novel methods for manipulating ion types in the solution and gas phases for the structural analysis of biomolecules using Mass Spectrometry
… to many fields. The advent of nanoelectrospray ionization (nESI) as a soft/low energy ionization technique has enabled the analysis of large, intact biomolecules. Most mass spectrometry experiments consist of three main steps: ionization, probe step(s), and mass analysis. The present work …

Ion Mobility and Gas-Phase Covalent Labeling Study of the Structure and Reactivity of Gaseous Ubiquitin Ions Electrosprayed from Aqueous and Denaturing Solutions
Gas-phase ion/ion covalent modification was coupled to ion mobility/mass spectrometry analysis to directly correlate the structure of gaseous ubiquitin to its solution structures with selective covalent structural probes. Collision cross-section (CCS) distributions were measured prior to ion/ion …
