Surface-induced dissociation of peptide ions in Fourier-transform mass spectrometry
American Chemical Society (ACS) - Tập 1 - Trang 413-416 - 1990
Evan R. Williams, Kent D. Henry, Fred W. McLafferty, Jeffrey Shabanowitz, Donald F. Hunt
Peptide molecular ion species up to m/z 3055 introduced into a Fourier-transform mass spectrometer can be made to undergo extensive fragmentation by electrically floating the ion cell. The proportion of ions dissociated increases with increasing voltage, with 48 eV producing the highest absolute abundance of fragment ions above m/z 200. At this energy, spectra closely resemble those from photodiss...... hiện toàn bộ
Intriguing Mass Spectrometric Behavior of Guanosine Under Low Energy Collision-Induced Dissociation: H2O Adduct Formation and Gas-Phase Reactions in the Collision Cell
American Chemical Society (ACS) - Tập 16 - Trang 1291-1304 - 2005
Robin Tuytten, Filip Lemière, Walter Van Dongen, Eddy L. Esmans, Erwin Witters, Wouter Herrebout, Benjamin Van Der Veken, Ed Dudley, Russell P. Newton
Regulated In Situ Generation of Molecular Ions or Protonated Molecules under Atmospheric-Pressure Helium-Plasma-Ionization Mass Spectrometric Conditions
American Chemical Society (ACS) - Tập 26 - Trang 1252-1255 - 2015
Rekha Gangam, Julius Pavlov, Athula B. Attygalle
In an enclosed atmospheric-pressure helium-plasma ionization (HePI) source engulfed with dehumidified ambient gases, molecular cations are generated from compounds such as toluene, bromobenzene, and iodobenzene. Evidently, the ionization is effected by a direct Penning mechanism attributable to interactions of the gas-phase analyte with metastable helium atoms. It is widely known that secondary io...... hiện toàn bộ
Detection and characterization of methionine oxidation in peptides by collision-induced dissociation and electron capture dissociation
American Chemical Society (ACS) - Tập 14 - Trang 605-613 - 2003
Ziqiang Guan, Nathan A. Yates, Ray Bakhtiar
Electron capture dissociation (ECD) and collision-induced dissociation (CID), the two complementary fragmentation techniques, are demonstrated to be effective in the detection and localization of the methionine sulfoxide [Met(O)] residues in peptides using Fourier transform ion cyclotron resonance (FTICR) mass spectrometry. The presence of Met(O) can be easily recognized in the low-energy CID spec...... hiện toàn bộ
The influence of material and mesh characteristics on transmission mode desorption electrospray ionization
American Chemical Society (ACS) - Tập 20 - Trang 584-592 - 2009
Joseph E. Chipuk, Jennifer S. Brodbelt

Comparison of LC and LC/MS methods for quantifying N-glycosylation in recombinant IgGs
American Chemical Society (ACS) - Tập 19 - Trang 1643-1654 - 2011
Sandipan Sinha, Gary Pipes, Elizabeth M. Topp, Pavel V. Bondarenko, Michael J. Treuheit, Himanshu S. Gadgil
High-performance liquid chromatography (LC) and liquid chromatography/electrospray ionization time-of-flight mass spectrometry (LC/ESI-MS) methods with various sample preparation schemes were compared for their ability to identify and quantify glycoforms in two different production lots of a recombinant monoclonal IgG1 antibody. IgG1s contain a conserved N-glycosylation site in the fragment crysta...... hiện toàn bộ
