Short description:

Omics platforms - Metabolomic Profiling

The platform has been designed to perform qualitative and quantitave metabolome analysis based on mass spectrometry. The platform allows global metabolic profiling based on LC and GC preseparation and detection and identification of metabolites by subsequent mass spectrometry. The high resolution instruments support verified identification of endogenous and exogenous chemicals in connection with existing and in-house spectra databases. These global analyses provide relative quantification and in targeted approaches also absolute quantification can be obtained in highly specified assays (prostaglandins or CoA-esters) and also in broader applications (serum metabolome profiling). The preprocessing for metabolite extraction is established for passive sampling of VOCs, eukaryotic body fluids, tissue, cellular models, and bacterials samples.

Major research issues/sites:

In respect to human health we focus on deciphering the effects of contaminants on the liver, immune, and respiratory system and model organisms. Of specific interest are the consequences of contaminants on the endogenous metabolome of very young children and the correlation of atopic diseases to the endogenous metabolism. The platform allows the global analysis of tissues and cellular models after exposition in terms of the transformation of the contaminants and the endogenous metabolome. Selected metabolites e.g. of the central carbon and nitrogen metabolism can be absolutely quantified by targeted analysis.

In respect to microbial ecology and biodegradation a focus lies on the targeted analysis of key transformation products of contaminants or key endogenous metabolites. Furthermore the functional analysis is supported by detecting the carbon and nitrogen flux in tissue and cellular eukaryotic and prokaryotic models.
