This study details an untargeted metabolomic approach using gas chromatography/mass spectrometry (GC/MS) for analyzing biological samples. The method enables comprehensive metabolic phenotyping and biomarker discovery in plasma, serum, and fecal water.
Area of Science:
- Analytical Chemistry
- Biochemistry
- Metabolomics
Background:
- Metabolomics offers powerful metabolic phenotyping and biomarker discovery from biofluids.
- Gas Chromatography-Mass Spectrometry (GC/MS) is a key technology in this field.
Purpose of the Study:
- To describe an untargeted metabolomic approach for profiling plasma, serum, and fecal water samples.
- To outline a comprehensive multistep procedure for metabolite analysis.
Main Methods:
- Sample preparation and derivatization (oximation/silylation).
- Data acquisition using Gas Chromatography/Quadrupole Time-of-Flight (GC/QToF) mass spectrometry.
- Data processing including extraction and metabolite identification.
Main Results:
- The described method allows for detailed profiling of metabolites in various biological samples.
- Successful application of GC/MS for untargeted metabolomic analysis was demonstrated.
Conclusions:
- This untargeted metabolomic approach provides a robust framework for metabolic phenotyping.
- The methodology facilitates biomarker discovery in clinical and research settings.
