Lipid Data Analyzer: Discrimination of structurally isomeric pairs of lipid standards (Control experiment 3)

Lipid Data Analyzer (LDA; http://genome.tugraz.at/lda2) provides automated and reliable annotation of lipid species and their molecular structures in high-throughput data from chromatography-coupled tandem mass spectrometry using embedded rule sets. Using various low- and high-resolution mass spectrometry instruments with several collision energies, the method's platform independence is proved. The software's reliability, flexibility, and ability to identify novel lipid molecular species may now render current state-of-the-art lipid libraries obsolete. In lipidomics LC-MS/MS experiments, structural isomers within one MS1 peak frequently occur. In this experiment, structural isomeric pairs from PC, PE, PG, PS and TG are mixed in one sample at various concentrations. The algorithm appropriately assigning the respective structural isomers is demonstrated. Control experiment 1 assays for this study can be found in the MetaboLights study MTBLS394. Control experiment 2 assays for this study can be found in the MetaboLights study MTBLS391. Murine liver lipidome experiment assays for this study can be found in the MetaboLights study MTBLS396. LipidBlast benchmarking assays for this study can be found in the MetaboLights study MTBLS397. HCD characterization and regioisomer detection assays for this study can be found in the MetaboLights study MTBLS462.
