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...

Method Development of Chemical Isotope Labeling of Cellular Extract and Biofluids on Metabolomics Profiling and Its Application for Disease Biomarker Discovery
DownloadFall 2019
Metabolomics aims at studying all the small molecules in biological samples. Compared to transcriptome and proteome, metabolome is highly sensitive to diverse individuals and environmental factors. Thus, metabolomics study has been used to understand individual variations caused by genes,...

Metabolomics by GC×GC-TOFMS: Overcoming Challenges from Sample Preparation to Data Analysis Towards Standardization of the Workflow
DownloadSpring 2021
Metabolomics is an ‘omics’ field, which involves the comprehensive characterization of metabolites using analytical chemistry technologies and statistical methods to interpret the results. The term metabolomics was coined about two decades ago as an analogy to other precedent omics approaches:...

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 Liquid Chromatography Mass Spectrometry Methods for the Identification and Quantification of Acylcarnitines in Biological Samples
DownloadFall 2012
The field of metabolomics follows the Greek premise where metabolic changes are believed to be indicative of disease. Acylcarnitines, for example, can be dysregulated in the presence of various diseases including genetic metabolic disorders and multiple sclerosis. Liquid chromatography mass...

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 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...

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...
