Determination of micelle mass by electrospray ionization mass spectrometry

Journal of Mass Spectrometry, 2005
AbstractBy electrospray ionization (ESI) mass spectrometry, micelle solutions of sodium cholate were investigated in detail in the presence and absence of ethanol. The average aggregation number could be evaluated from the spectra acquired under conditions where soft collisions adequate to measure the micelle solution were induced, and the value agreed

Ion suppression effect in desorption electrospray ionization and electrospray ionization mass spectrometry

Rapid Communications in Mass Spectrometry, 2017
Rationale Although it is claimed that desorption electrospray ionization (DESI) causes less ion suppression effects than electrospray ionization (ESI), a related investigation with quantification measurement of ion suppression effects is absent.

Miniaturization of Electrospray Ionization Mass Spectrometry

Applied Spectroscopy Reviews, 2003
1. Abstract The development of electrospray ionization (ESI) has proved an enormous breakthrough in structural biology because it provides a means for transferring large biological molecules into the gas-phase as intact charged ions. In the post-genomics era, increased attention has been focused on mass spectrometry techniques capable of providing ...

Conformational effects in protein electrospray‐ionization mass spectrometry

Mass Spectrometry Reviews, 2015
Electrospray‐ionization mass spectrometry (ESI‐MS) is a key tool of structural biology, complementing the information delivered by conventional biochemical and biophysical methods. Yet, the mechanism behind the conformational effects in protein ESI‐MS is an object of debate.

Electrode‐assisted desorption electrospray ionization mass spectrometry

Journal of Mass Spectrometry, 2010
AbstractA new ion source has been developed for rapid, noncontact analysis of materials at ambient conditions. The method provides desorption of analytes under ambient conditions directly from different surfaces with little or no sample preparation. The new method, termed electrode‐assisted desorption electrospray ionization (EADESI), is on the basis ...

Monitoring Glycation of Lysozyme by Electrospray Ionization Mass Spectrometry

Journal of Agricultural and Food Chemistry, 2000
Electrospray ionization mass spectrometry (ESI-MS) was used to study the glycation of lysozyme by D-glucose (LZM-G) and by D-fructose (LZM-F) under dry heating conditions in the presence and in the absence of oxygen. ESI-MS proved to be a precise method for monitoring protein glycation with respect to following the extent of glycation and changes in ...

New developments in biochemical mass spectrometry: electrospray ionization

Analytical Chemistry, 1990
The principles, development, and recent application of electrospray ionization-mass spectrometry (ESI-MS) to biological compounds are reviewed. ESI-MS methods now allow determination of accurate molecular weights for proteins extending to over 50,000, and in some cases well over 100,000.

Glycerophospholipid Identification and Quantitation by Electrospray Ionization Mass Spectrometry

2007
Glycerophospholipids are the structural building blocks of the cellular membrane. In addition to creating a protective barrier around the cell, lipids are precursors of intracellular signaling molecules that modulate membrane trafficking and are involved in transmembrane signal transduction.

Electrospray ionization mass spectrometry of biomolecules

Nature, 1990
The novel ionization technique of electrospray now allows the convenient mass spectrometric analysis of proteins and other biological molecules directly from liquids The molecular weights of protein can be determined to better than 0.01 per cent mass accuracy.
