Development and Application of ESI-MS Based Techniques for Quantitative Determination of Protein-Carbohydrate Interactions
DownloadFall 2016
This thesis describes the development and application of mass spectrometry methods to study protein-ligand interactions in vitro. Liquid sample desorption electrospray ionization mass spectrometry (liquid sample DESI-MS) was employed to quantify protein-carbohydrate interactions in aqueous buffer...

Development and Applications of Chemical Isotope Labeling Methods for Metabolome Sample Normalization and Liquid Chromatography-Mass Spectrometry-Based Metabolomics
DownloadFall 2015
Metabolomics refers to the global study of the metabolome of a biological system where comprehensive and systematic profiling of all metabolites in a given biological sample (i.e., the metabolome) is performed. As the end product of biological processes, the status of metabolites could reflect...

Development and Applications of Stable Isotope Labelling Liquid Chromatography Mass Spectrometry for Quantitative Proteomics
DownloadSpring 2011
This thesis describes the characterization, automation, and applications of a stable isotope labelling method for quantitative proteomics by mass spectrometry. Known as 2MEGA, the method uses guanidinylation to convert peptide lysine residues to homoarginine followed by reductive methylation of...

Development of Isotope Labeling Liquid Chromatography Mass Spectrometry for Biofluid Metabolomics and Applications in Disease Studies
DownloadSpring 2014
Metabolomics is a research field focusing on global study of all the metabolites present in a biological system (i.e., the metabolome). Metabolome analysis involves identifying and quantifying as many small molecule metabolites as possible in a biological sample. Metabolomics has attracted much...

Development of New Late-Stage Labeling Methods with Labeled Carbon for Stabilized Carboxylic Acids and α-Amino Acids
DownloadFall 2023
Isotope labeling of small molecules is a crucial tool for drug discovery and understanding biochemical processes. Expanding the toolbox of a radiochemist with methods that allow late-stage labeling is therefore important. Of the methods that have been developed, the use of isotopically labeled...

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...

Separation and characterization of polycyclic aromatic hydrocarbons and azaarenes using normal phase liquid chromatography and electrospray ionization mass spectrometry
DownloadFall 2016
Normal phase liquid chromatography (NPLC) is widely used for separating petroleum into compound classes, such as polycyclic aromatic hydrocarbons (PAHs) and polar nitrogen containing compounds. The charge-transfer and hypercrosslinked polystyrene NPLC phases provide unique selectivities for PAHs....

Study of Non-Covalent Protein-Carbohydrate Interactions using Electrospray Ionization Mass Spectrometry
DownloadFall 2012
This thesis describes the development and application of electrospray ionization mass spectrometry (ESI-MS) methods to study protein-carbohydrate interactions in vitro. The affinities (Ka) of two recombinant fragments of Clostridium difficile toxins (TcdA & TcdB) and a library of the most...
