LIPID SCREENING PLATFORM ALLOWING A COMPLETE SOLUTION FOR LIPIDOMICS RESEARCH

机译:脂质筛查平台,为脂质学研究提供完整的解决方案

摘要

Known lipid molecules of a matrix are grouped into lipid classes and the lipid classes are further grouped into a pass-through group and a mobility separation group based on isobaric interferences. A separation system separates known lipid molecules from a matrix sample and an ion source ionizes the matrix sample. Two injections are performed. For the first injection a DMS device is put into passive mode, and for the second injection the DMS device is used to resolve isobaric interferences. A tandem mass spectrometer performs MRM scans of the pass-through group for the first injection and MRM scans of the mobility separation group for the second injection. A processor quantitates each lipid molecule in the matrix sample by comparing the MRM intensity values obtained for the first and second injections to MRM intensity and concentration values for known standards of the known lipid molecules of the matrix.
