Synchronized dual-polarity electrospray ionization mass spectrometry [PDF]
Journal of the American Society for Mass Spectrometry, 2009 This work describes the synchronized dual-polarity (DP) electrospray ionization (ESI) method and demonstrates the first DP ESI mass spectra obtained using two mass spectrometers. Stable double Taylor cones were produced by applying two counter electric voltages with opposite polarities to one electrosprayer.

Electrospray ionization mass spectrometry with wooden tips: A review
Analytica Chimica Acta, 2022 Electrospray ionization (ESI) is a powerful ionization technique in mass spectrometry (MS). There has been an increasing interest for the new development of ESI technique to extend its applications. ESI-MS with wooden tips (wooden-tip ESI-MS), an ESI technique invented in 2011, enabled not only new applications but also new insights into the ESI ...

Electrospray Post-Ionization Mass Spectrometry of Electrosurgical Aerosols [PDF]
Journal of the American Society for Mass Spectrometry, 2011 The feasibility of electrospray (ES) ionization of aerosols generated by electrosurgical disintegration methods was investigated. Although electrosurgery itself was demonstrated to produce gaseous ions, post-ionization methods were implemented to enhance the ion yield, especially in those cases when the ion current produced by the applied ...

Electrospray ionization mass spectrometry of biotin binding to streptavidin [PDF]
Journal of the American Society for Mass Spectrometry, 1995 Stepwise binding of biotin to streptavidin via several intermediates was monitored with electrospray ionization mass spectrometry (ESIMS). Protein ligand interactions that result in conformational changes could be recognized with ESIMS by a mass shift and a change of the average multiple charge state of this protein.

FEBS Letters, EarlyView.This work presents the characterization of MvoDUF2193, a Methanococcus voltae (Mvo) protein from the domain of unknown function (DUF) 2193 family. We demonstrate that MvoDUF2193 binds a single [4Fe–4S] cluster per subunit and that cluster occupancy regulates the transition from an apo tetramer to a [4Fe–4S] monomeric form. This structural transition is

Electrospray ionization tandem mass spectrometry of monoketone curcuminoids [PDF]
Rapid Communications in Mass Spectrometry, 2020 RationaleAlthough monoketone curcuminoids (MKCs) have been largely investigated due to their biological activities, data on the gas‐phase fragmentation reactions of protonated MKCs under collision‐induced dissociation (CID) conditions are still scarce.
