“Discovery lipidomics workflows enabled by high resolution Orbitrap mass spectrometry and LipidSearch software”


Application of lipidomics profiling to disease phenotype analysis is a rapidly growing aspect of translational medical and systems biology research. Identification of lipids by discovery lipidomics requires sophisticated software with an extensive lipid database. One of the main challenges with untargeted lipidomics is the automated identification of lipids from LC/MS-MS data. We are working with many of the lipidomics experts to address this challenge, and to introduce standards for lipid identification and reporting by mass spectrometry.

The high resolution, mass accuracy and dynamic range of Orbitrap mass spectrometers combined with LipidSearch software uniquely addresses the lipid data analysis bottleneck. New algorithms were introduced specifically to reduce false positives, improve peak integration and to help automate the data review. The application of the LC-MS discovery lipidomics workflow is illustrated for the analysis of lipid extracts from Fumonisin B1 treated mice and for human plasma samples from subjects taking flax seed and fish oil supplements compared to a normal diet.
