Apparent gas-phase acidities of multiply protonated peptide ions: Ubiquitin, insulin B, and renin substrate
American Chemical Society (ACS) - Tập 7 - Trang 1211-1218 - 1996
The gas-phase deprotonation reactions of multiply protonated bovine ubiquitin, insulin chain B, and renin substrate tetradecapeptide ions have been studied in a Fourier transform ion cyclotron resonance mass spectrometer coupled with an external electrospray source. Rate constants were measured for the reactions of these peptide ions with a series of reference compounds of known gas-phase basiciti...... hiện toàn bộ
Ultraviolet, Infrared, and High-Low Energy Photodissociation of Post-Translationally Modified Peptides
American Chemical Society (ACS) - Tập 29 - Trang 270-283 - 2017
Mass spectrometry-based methods have made significant progress in characterizing post-translational modifications in peptides and proteins; however, certain aspects regarding fragmentation methods must still be improved. A good technique is expected to provide excellent sequence information, locate PTM sites, and retain the labile PTM groups. To address these issues, we investigate 10.6 μm IRMPD, ...... hiện toàn bộ
Open access atmospheric pressure chemical ionization Mass spectrometry for routine sample analysis
American Chemical Society (ACS) - Tập 6 - Trang 387-393 - 1995
We report the introduction and use of an atmospheric pressure chemical ionization liquid chromatography-mass spectrometry instrument that has been designed specifically for use by the synthetic chemist on an open access, walk-in basis. This instrument has been configured with an easy-to-use sample log-in terminal that requires the user to provide only a sample identification number and a user name...... hiện toàn bộ
Remarkable amine-TFA self assembly
American Chemical Society (ACS) - Tập 15 - Trang 356-362 - 2004
Supramolecular assemblies that are formed between amines and trifluoroacetic acid were studied using electrospray ionization mass spectrometry. Distinctive association behavior of primary, secondary, and tertiary amines with trifluoroacetic acid upon identical experimental conditions is observed and indicates that steric effects dominate in the formation of these protonated clusters. Extraordinary...... hiện toàn bộ
Gas-phase C-F bond cleavage in perfluorohexane using W-, Si-, P-, Br-, and I-containing ions: Comparisons with reactions at fluorocarbon surfaces
American Chemical Society (ACS) - Tập 9 - Trang 1158-1167 - 1998
Gas-phase reactions of W-, Si-, P-, Br-, and I-containing ions with the target molecule perfluorohexane at low collision energies (<15 eV) parallel known ion/surface reactions of the same projectile ions at fluorinated self-assembled monolayer surfaces. Charge exchange, dissociative charge exchange, and fluorine atom abstraction are observed and the majority of the projectile ions also undergo rea...... hiện toàn bộ
Identification of fragmentation channels of dinucleotides using deuterium labeling

Cryogenic Vibrational Spectroscopy Provides Unique Fingerprints for Glycan Identification
American Chemical Society (ACS) - Tập 28 - Trang 2217-2222 - 2017
The structural characterization of glycans by mass spectrometry is particularly challenging. This is because of the high degree of isomerism in which glycans of the same mass can differ in their stereochemistry, attachment points, and degree of branching. Here we show that the addition of cryogenic vibrational spectroscopy to mass and mobility measurements allows one to uniquely identify and chara...... hiện toàn bộ
