Metobolomics and Lipidomics Services

The Mass Spectrometry Laboratory offers metabolomics and lipidomics research services including:

  • LC/MS method development
  • Qualitative and quantitative analysis of small molecules or drugs in biological samples
  • Sample preparation (e.g. homogenization, extraction)
  • Omics data analysis and help with the experimental design for omics studies.

Range of metabolites covered (by established methods or methods in development)

Targeted analysis

  1. α-Dicarbonyls
  2. Advanced glycation end-products
  3. Monomethylfumarate
  4. Sphingoid bases and sphingosine 1 phosphate

Untargeted and semi-targeted anaylsis

  1. Metabolomics: metabolites covering glycolysis, TCA cycle, pentose phosphate pathway, amino acids, nucleotides and vitamin and cofactor metabolism
  2. Lipidomics: metabolites covering sphingolipid, phospholipid, cholesterol and triglyceride metabolism

For new method development projects, the mass spectrometry committee has to approve the project funding and secure that number of sample that will cover the cost of method development.

Standard prices as stated in the user guidelines are € 40,-/sample for targeted analyses and € 80,-/sample for untargeted analyses, e.g. Lipidomics and Metabolomics screens. 

Instruments

LC/MS lab

The lab is equipped with two state-of-the art liquid chromatography–mass spectrometry (LC/MS) systems to cover both the targeted and untargeted metabolomics research questions
