State-of-the-art technologies such as mass spectrometry coupled with gas or liquid chromatography allow us to guarantee quantitative and ultra-sensitive analyzes on hundreds of lipid species in various biological matrices.

Expertise and services

1. Complex profiling by LC-ESI-MS/MS

  • Glycerophospholipids (238): PC, LPC, PE, LPE, plasmalogen PE, PI, PG, LPG, BMP, PS, PA
  • Sphingolipids (70): Sphingomyelin (SM), ceramides, dihydroceramide (DHC), acylceramides
  • Neutral lipids (135): TAG, DAG, MAG, CE, cholesterol

2. Targeted approach for studies of specific metabolic pathways (LC-MS/MS and GC-EI/CI-MS)

  • Metabolites from the microbiota: stanols (coprostanol, epicoprostanol, ethylcoprostanol), bile acids (primary, secondary, conjugated)
  • Free fatty acids (FFA) (27 lipids): 15:0, 16:0, 16:1, 17:0, 18:0, 18:1, 18:2, 18:3 (w3 and w6), 20: 0, 20:1, 20:2, 20:3 (w3 and w6), 20:4, 20:5, 22:0, 22:1, 22:4, 22:6, 23:0, 24:0 , 24:1
  • Cholesterol synthesis pathway: squalene, lanosterol, desmosterol, lathosterol, cholesterol
  • Intestinal absorption markers: phytosterols (campesterol, β-sitosterol, stigmasterol), cholestanol

Matrices: Biofluids (plasma, serum, lipoproteins (VLDL, LDL HDL)), faeces, tissue (liver, adipose tissue, brain, heart, muscle), others (exosomes, mitochondria, cells, bacteria, etc.)
