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...

Differential 15N2-/14N2-isotope Dansylhydrazine Labeling and LC-MS for Quantification of the Human Carbonyl Metabolome
DownloadFall 2011
The objective of this work was the design and use of paired labeling reagents that are chemically identical but isotopically different to provide a simple and robust means of quantitative mass spectrometry (MS) based metabolome profiling. Herein is presented the differential 15N2-/14N2-isotope...

Development and Application of Chemical Isotope Labeling Methods for Metabolomics Data Processing and Liquid Chromatography-Mass Spectrometry-Based Metabolomics
DownloadSpring 2016
Metabolomics is the study of chemical processes involving small-molecule metabolites in a given biological system. These small molecules are downstream outputs of cellular activities. An understanding of the metabolome change can help us to visualize perturbations in the genome or proteome from...

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...

In-line Ozonolysis coupled to Mass Spectrometry- A New Dimension of Structural Determination for Lipids
DownloadFall 2014
The location of double bonds within unsaturated lipids can greatly affect their biological functions. Liquid chromatography coupled to mass spectrometry (LC/MS) has become a powerful tool for lipid separation and structural elucidation. However, the determination of double bond position remains...

Application of Electrospray Ionization Mass Spectrometry to Study Protein-Ligand Interactions and Enzyme Kinetics
DownloadFall 2015
This thesis describes the development and application of electrospray ionization mass spectrometry (ESI-MS) to study the noncovalent protein-ligand interactions and also investigate the kinetic of enzymatic reactions. The rate of glycolipids cleavage by the human neuraminidase 3 (hNEU3) was...
