Isotope Labeling Liquid Chromatography Mass Spectrometry: Metabolite Identification and Human Salivary Metabolome Profiling
DownloadFall 2012
The objective of this work was to use paired labeling reagents that are chemically identical but isotopically different to provide a simple and robust way of mass spectrometry (MS)-based metabolome profiling. A differential 13C-/12C-isotope dansyl chloride (DnsCl) derivatization strategy has been...

Quantitative Characterization of Noncovalent Protein-Carbohydrate Interactions using Electrospray Ionization Mass Spectrometry
DownloadFall 2015
The interactions between water-soluble proteins and carbohydrates found on the surfaces of cells play important roles in many physiological and pathological cellular processes. Carbohydrates function as receptors for signaling, cellular recognition and adhesion, and pathogen infections. This...

Development of Mass Spectrometric Methods for Membrane Proteome Analysis and Protein Sequence Mapping
DownloadSpring 2014
This thesis work mainly focused on the development of mass spectrometric methods for membrane proteome analysis and protein sequence mapping. First, the comparison of the performance of RapiGest-, PPS- and SDS-based sample preparation methods for shotgun membrane proteome analysis was...

Study of Non-Covalent Protein-Carbohydrate Interactions by Nanoelectrospray Ionization Mass Spectrometry and Surface Plasmon Resonance
DownloadFall 2015
This thesis describes the application of electrospray ionization mass spectrometry (ESI-MS) techniques to identify and quantify antibody-antigen interactions in vitro. Also potential application of nanodiscs (ND) as membrane model in ESI-MS and surface plasmon resonance (SPR) spectroscopy has...

Fall 2016
This thesis describes the development of mass spectrometry methods to study protein-ligand interactions in vitro. Liquid sample desorption electrospray ionization mass spectrometry (liquid sample DESI-MS) was first applied to quantify protein-carbohydrate interactions in aqueous ammonium acetate...
