Probing Cyanocuprates by Electrospray Ionization Mass Spectrometry [PDF]
Organometallics, 2010 Solutions of CuCN/(RLi)n (n = 0.5, 0.8, 1.0, and 2.0 and R = Me, Et, nBu, sBu, tBu, and Ph) in tetrahydrofuran are analyzed by electrospray ionization mass spectrometry. In all cases, organocuprate anions are observed, whose exact nature depends on the reagent stoichiometry.

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 ...

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 ...
