Get started with these easy-to-implement methods for global lipid profiling
Lipidomics Quantification of lipids in complex biological samples is challenging and often requires a detailed knowledge of lipids and lipid analysis methods. The inherent complexity of the lipidome means that identifying and quantifying different lipid classes and...
sMRM Pro Builder template tutorial
The sMRM Pro Builder template is an Excel-based tool that can help you implement large panels of analytes in your lab. The Excel sheet will take your preliminary experimental results and compute retention times, retention time window widths and dwell time weighting to optimize your targeted assay.
High complexity of the lipidome
The complexity of the lipidome is diverse in the structure and there are many combinatorial isoforms that are available within nature. Currently, many different techniques are required to fully characterize a lipid molecule. What if you could do it in a single...
What is the Zeno threshold and what does it do?
With the introduction of the Zeno trap on the ZenoTOF 7600 system, sensitivity improvements on the order of 4 to 25x can be seen for MS/MS analysis, because of the optimization of duty cycle.1 When concentrations are low and peak intensities are limited, this bump in...
Tips and tricks: setting up LC-MS/MS methods for lipid mediator profiling
Starting up a workflow for lipid mediator analysis can be challenging. Hundreds of distinct fatty acid-derived molecules can be produced biologically (i.e., enzymatically) and/or via non-enzymatic routes. Additionally, various biosynthetic pathways yield both...
Separation anxiety: Choosing the best approach to quantify the lipidome
Front-End Solutions for Lipid AnalysisWhich method should you choose? Lipids are a diverse group of compounds that serve many purposes. They are the basis for key biological entities including cell membranes, hormones, and lipoproteins and are involved in a variety...
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...
The World Has its Eyes on Precision Medicine
What if we could understand and then treat diseases on an individualized level, in a way that was tuned to a person’s individual biology? Not in a futuristic, ‘wave a high-tech scanner across a person’s body’ way, but in a legitimate ’I can run a lab test and know the best action to take’ way. This is the promise of Precision Medicine, to deliver the right treatment to the right patient, at the right time, predicting more accurately which treatments will work for certain groups of patients, in contrast to the pervasive one-size-fits-all approach. More specifically, if we could provide a comprehensive report at the molecular level of an individual (based on genome, proteome, or metabolome profiles), a physician could be much better informed to make optimal treatment decisions. And if we could track these profiles over time, a person could adjust their lifestyle to focus on long-term wellness.
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!
