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...

Screening carbohydrate libraries for protein interactions using the direct ESI-MS assay: Applications to libraries of unknown concentration
Download2014
El-Hawiet, Amr, Klassen, John S., Kitova, Elena N.
A semiquantitative electrospray ionization mass spectrometry (ESI-MS) binding assay suitable for analyzing mixtures of oligosaccharides, at unknown concentrations, for interactions with target proteins is described. The assay relies on the differences in the ratio of the relative abundances of...

Reliable determinations of protein-ligand interactions by direct ESI-MS measurements: Are we there yet?
Download2012
Klassen, John S., Kitova, Elena N., Schnier, Paul D., El-Hawiet, Amr
The association-dissociation of noncovalent interactions between protein and ligands, such as other proteins, carbohydrates, lipids, DNA, or small molecules, are critical events in many biological processes. The discovery and characterization of these interactions is essential to a complete...

McMullen, Todd, Burrell, Robert
NFRF Exploration awarded in 2020: Personalized therapy for patients with cancer remains one of the most important challenges facing clinicians and researchers. In this proposal we describe a point-of-care device that can diagnose disease, or provide prognostic information, by quantifying protein...

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...
