Differential ion mobility separations in the low-pressure regime
(American Chemical Society, 2018-01-02)Ion mobility spectrometry (IMS) in conjunction with mass spectrometry (MS) has emerged as a powerful platform for biological and environmental analyses. An inherent advantage of differential or field asymmetric waveform ... -
Fast and effective ion mobility-mass spectrometry separation of D-amino-acid-containing peptides
(American Chemical Society, 2017-11-01)Despite often minute concentrations in vivo, d-amino acid containing peptides (DAACPs) are crucial to many life processes. Standard proteomics protocols fail to detect them as d/l substitutions do not affect the peptide ... -
Infrared multiple photon dissociation spectroscopy of group I and group II metal complexes with Boc-hydroxylamine
(WILEY-BLACKWELL, 2013-08-30)RATIONALE Hydroxamates are essential growth factors for some microbes, acting primarily as siderophores that solubilize iron for transport into a cell. Here we determined the intrinsic structure of 1:1 complexes between ... -
Ultrahigh-resolution differential ion mobility separations of conformers for proteins above 10 kDa: onset of dipole alignment?
(American Chemical Society, 2014-11-04)Biomacromolecules tend to assume numerous structures in solution or the gas phase. It has been possible to resolve disparate conformational families but not unique geometries within each, and drastic peak broadening has ...
