LipidomeDB Data Calculation Environment Has Been Updated to Process Direct-Infusion Multiple Reaction Monitoring Data

LipidomeDB Data Calculation Environment (DCE), a web application for processing data from direct-infusion tandem mass spectrometer data on lipids, was described by Zhou et al. (, Lipids, 46, 879-884). The original version processed multiple precursor and/or neutral loss scans on multiple samples. A recent update to LipidomeDB DCE, , extends LipidomeDB DCE's functionality to process data acquired in multiple reaction monitoring (MRM) mode by direct-infusion mass spectrometry. Both the precursor-neutral loss workflow and the MRM workflow remove signals due to isotopic overlap of lipid analytes and calculation of the amount of each target lipid in comparison with internal standards.
