Discovery based metabolomics in which LC-MS or LC-MS/MS is used to determine differences in abundance of metabolites in a given sample set (control vs experimental for example). Identification of the potential biomarkers can performed by high-resolution mass spectrometry on the Bruker Impact II QqTOF, using 4-D omic analysis on the Bruker timsTOF Pro2, or using unit mass MSn analysis on the LTQ-XL. Metaboscape 2025 is used for the bioinformatics, including spectral library matching and basic statistical anlaysis.
Quantitative metabolomics study of a complex lipid sample. Either a shotgun approach (left) or LC-MS (right) based approach are shown here.
