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.

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 ...

Transformation of neutral rhenium compounds during electrospray ionization mass spectrometry [PDF]
, 1997 Four neutral rhenium compounds were examined by electrospray ionization mass spectrometry. Acetonitrile solutions of (Ind)Re(CO)3 (Ind = indenyl) and (Cp)Re(CO)3 (Cp = cyclopentadienyl) gave rise to [Re(CO)3(CH3CN)3]+ ions.

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 ...

Topoisomer Differentiation of Molecular Knots by FTICR MS: Lessons from Class II Lasso Peptides [PDF]
Journal of the American Society for Mass Spectrometry 22 (2011)
467-479, 2011 Lasso peptides constitute a class of bioactive peptides sharing a knotted structure where the C-terminal tail of the peptide is threaded through and trapped within an N-terminalmacrolactamring. The structural characterization of lasso structures and differentiation from their unthreaded topoisomers is not trivial and generally requires the use of ...

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.

Journal of the American Chemical Society, 2015 We report a new method for the mass spectrometric detection of fleeting reaction intermediates in electrochemical reactions utilizing a "waterwheel" working electrode setup. This setup takes inspiration from desorption electrospray ionization (DESI) mass
