Electrospray Ionization-Induced Protein Unfolding [PDF]

Journal of the American Society for Mass Spectrometry, 2012
Electrospray ionization mass spectrometry (ESI-MS) measurements were performed under a variety of solution conditions on a highly acidic sub-fragment (B3C) of the C-terminal carbohydrate-binding repeat region of Clostridium difficile toxin B, and two mutants (B4A and B4B) containing fewer acidic residues.

Electronic Spectroscopy of Isolated DNA Polyanions [PDF]

, 2018
In solution, UV-vis spectroscopy is often used to investigate structural changes in biomolecules (i.e., nucleic acids), owing to changes in the environment of their chromophores (i.e., the nucleobases).

About the Electrospray Ionization Source in Mass Spectrometry: Electrochemistry and On-chip Reactions

CHIMIA, 2009
The present work shows that the electrochemical properties of electrospray ionization (ESI) can be used to add functions to the process. As example, we show how the choice of the electrode material can be used to study interactions between metal
