Wang, Chu-Fan

Chemical isotope labeling liquid chromatography-mass spectrometry (CIL LC-MS) is a powerful technique in metabolomics, offering extensive coverage of the metabolome. This method involves dividing metabolites into sub-groups based on their functional groups and subjecting them to specific labeling...

Peng, Jun

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...

Tatlay, Jaspaul

The analysis of thousands of metabolites and lipids for discovery of metabolite biomarkers for disease monitoring and diagnosis requires the highest sensitivity and robust methods. Metabolomics is the study of metabolites found in the body, which can be used to discover biomarkers of disease or...

Zuniga, Azeret

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...

Dawe, Margot Renee

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...

Curle, Jared P

The objective of this work was to assess the impact of reaction conditions for isotopic labeling of metabolites prior to analysis using liquid chromatography mass spectrometry (LC-MS). Differential isotope 12C/13C dansyl chloride was used to label metabolites containing either primary amines,...

Zheng, Jiamin

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...
