Overview

The Lipidomics Shared Resource builds on the unique expertise of key personnel in sphingolipid chemistry, analysis, and biology providing intellectual and physical resources to enhance the understanding of bioactive sphingolipids and lipids in signal transduction and cell regulation.

Sphingolipids are recognized as key components regulating fundamental cell biology processes regulating transmembrane signaling. Diversity of bioactive sphingolipids and their interconnected metabolism provide a network of pathways. Key sphingolipid metabolites are: ceramides (Cer), sphingosine (Sph), sphingosine 1-phosphate (S1P), and ceramide 1-phosphate (Cer1P).

Services & Expertise

The Lipidomics Shared Resource is designed to support research in lipidomics by providing advanced methodology and expertise for both synthesis and analysis of bioactive lipids in a cost-effective manner, with a focus on several key areas:

  • Providing qualitative and quantitative analysis of >300 sphingolipids using high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) technologies.
  • Providing analytical method development of new lipid components.
  • Providing and developing synthetic lipid tools/standards, including functionalized and fluorescent ceramides, 17C-sphingolipids, or synthetic lipid analogs, including organelle-targeted sphingolipids.
  • Mentoring investigators in the understanding of lipid biology through lipid chemistry, experimental design, selection of lipids of interest, and interpretation of the analytical data.
