The Latest and Greatest for Improving Lipidomic Analysis by Mass Spectrometry
Differential Mobility Separation (DMS) resolves multiple lipid classes within complex lipid matrices prior to MS analysis to enable more confident identification of lipid species and more accurate quantitation by MS/MS. Lipidomics research has progressed rapidly in...
Why Study Lipids?
I had an opportunity to follow up with Steven M Watkins, Ph.D. to talk about the importance of studying lipids in disease. Steve has been working in the lipids field for over 20 years and is one of the foremost experts in lipid biology. Steve founded Lipomics in 2000, an early metabolomics company focused on quantitative lipidomics and had followed that company through a series of changes that led to its involvement in the clinical diagnostic development and global metabolomics. Steve authored over 70 peer-reviewed publications including several book chapters on lipids and lipid metabolism. His presentations on this topic are fascinating and very informative, so I wanted to capture some of his thinking here!
Simplify and Improve the Analysis of Lipid Molecular Species Using SelexION Technology
Analyzing lipids can be tricky. Lipids tend to have a wide variety of chemical structures, and this makes it virtually impossible to find one LC method that can resolve all lipid species. Therefore, multiple LC methods are often used. Also, there is widespread isobaric and isomeric overlap between different lipid classes and species, therefore separating lipid compounds, using an orthogonal separation prior to mass analysis is important.
