Lipids are molecules generally soluble in organic solvents. They are known for their role in energy storage and structuring of cellular structures, but they also play an important signaling role in many diseases. The lipids may be present in very small or very large quantities, with extremely heterogeneous structures. It is therefore difficult to provide an overall analysis of these molecules, because of their complexity. The analyzes are family-dependent.

Metatoul proposes to quantify these molecules by conventional methods of gas and liquid chromatography coupled or not with mass spectrometry but also NMR, in all kinds of micro-samples: biological fluid (plasma, urine ...) cells, plant tissues (liver, brain, kidney, heart, intestine, muscle ...).

Analyses :

  • Neutral lipids (without DAG) by GC
  • Neutral lipids (with DAG) by GC
  • Total fatty acids by GC
  • Free fatty acids by GC
  • Eicosanoids by LC-MS
  • Phospholipids by LC-MS
  • Ceramide and sphingomyeline by LC-MS
  • PIPs by LC-MS
  • Oxysterols by GC-MS
  • Sphingosine, sphinganine by LC-MS
  • Sphingosine phosphate by LC-MS
  • Endocanabinoid by LC-MS
  • Isoprostane by LC-MS
  • LPA-LPC by LC-MS
  • Sphingolipids by LC-MS
  • Bile acids by LC-MS
  • 13C fatty acid profiling by GC-MS
    Chromato lipido
    chromato lipido2

Research and Development in Lipidomics:

  • Development of overall analytical methods of lipids by high resolution LC-MS.
  • Development of overall analytical methods of sphingolipids by high-resolution LC-MS.
  • Development of methods for quantification of isoprostanes by LC-MS.
