Development and application of mass spectrometry for bioanalysis of proteins and metabolites
DownloadSpring 2011
The proteome, a hybrid term from protein and genome, is the total set of proteins expressed by a genome in a cell, tissue, or organism at a given time. Proteomics, the study of the proteome, is concerned with a variety of topics such as identity, quantity, activity, structure, protein-protein...

Development and Applications of Mass Spectrometric Methods for Proteome Analysis and Protein Sequence Characterization
DownloadFall 2013
Mass spectrometry (MS) is widely used in proteomic work for protein identification and characterization. A key to the success of MS for protein analysis is related to sample preparation. Current sample preparation methods do not meet all the needs of protein or proteome analysis. My thesis work...

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...
