Short description:

Omics platforms – Qualitative and quantitative proteomics by mass spectrometry

The platform has been designed to perform qualitative and quantitave protein and proteome analysis. On the single protein level protein characterisation like protein modifications and protein-protein interactions are the most relevant applications. On the proteome level we perform global and targeted analysis of eukaryotic tissue, or cellular or bacterial extracts. The subsequent pathway analysis enables the detection of e.g. the mode of action of environmental contaminants on the chosen biological model. There are several techniques of isotopic labelling established that allow the accurate quantification in eucaryotic models like SILAC (stable isotope labelling of amino acids in cell culture) or flux analyis in bacterial communities (Protein stable isotope probing: Protein-SIP).

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. Therefore the global analysis of tissues and cellular models after exposition is assessed in terms of relative abundance. Selected proteins can be absolutely quantified by targeted analysis. Furthermore the functional analysis is supported by selected detection of post translational modifications like phosphorylation, acetylation and ubiquitinylation.

In respect to microbial ecology and biodegradation we analyse pure cultures by global and targeted analysis and apply metaproteomic approaches using isotopically labelled substrates to identifying and following the atomic fluxes in order to clearify structure and function of microbial consortia.
