Metabolomics
Metabolite Profiling and Small Molecule Mass Spectrometry
The Metabolomics Service and Research Facility provides services for the quantitative analysis of small molecules and metabolites.
Biological research in the post-genomic era has become largely dependent on advanced technologies and high-end instrumentation, allowing large-scale analysis of biological systems and processes. The most recent approach in -omics technologies, metabolomics, aims for a comprehensive and quantitative picture of small biomolecules in biological samples. The analysis of metabolomes allows the direct read-out of molecular phenotypes, representing the nexus of interactions between the genome and the environment. The beauty of the approach is that the metabolome directly represents the biochemical condition of cells, tissues, and organisms, thus allowing insights into perturbed biochemical pathways.
Our LC-MS/MS platforms provide both targeted and nontargeted metabolomics analysis of biological samples, revealing changes in metabolic pathways, consequences of various perturbations or simply quantifying small molecules of any origin. The facility has established methods for more than 1000 metabolites and additionally offers methods development on demand.
We offer:
- Targeted metabolomics.
- Stable isotope tracer analysis.
- Global (nontargeted) metabolite profiling.
- Small molecule analysis: identification & quantification.
We thank the Vienna Business Agency - a service offered by the city of Vienna for generous funding of the implementation of this Core Facility. To learn more about our research, please check our publications.
Targeted LC-MS/MS
We provide analysis of user-defined compounds in extracts from biological samples by targeted liquid chromatography-tandem mass spectrometry (LC-MS/MS). Our services are not limited to biomolecules but include other small molecules such as drugs.
The facility has a growing portfolio of LC-MS/MS methods for almost 1000 small molecules spanning over a wide variety of metabolites from different substance classes such as amino acids, bile acids, carboxylic acids (e.g. citric acid, stearic acid), coenzymes (NAD+/H, Acetyl-CoA/CoA, etc.), ketone bodies, lipids, mono amines (dopamine etc.), nucleoside tri-, di-, mono-phosphates, coenzymes (NAD+/H, Acetyl-CoA/CoA, etc.). We also offer methods development for small molecule analysis on demand.
We offer the analysis of panels consisting of metabolites of biochemical pathways such as the TCA cycle, glycolysis, purine and pyrimidine metabolism, urea cycle, amino acid metabolism or the pentose phosphate pathway but also tailor-made panels.
Additionally, we offer methods development on demand and more sophisticated assays such as stable isotope tracer analysis (e.g. 13C, 15N). In addition to relative quantification, the absolute quantification of metabolites is also offered.
Non-targeted LC-MS/MS or metabolite profiling
The facility offers global metabolite profiling employing liquid chromatography on-line coupled to high-resolution tandem mass spectrometry. Each sample is measured twice, with two different separation techniques hydrophilic interaction liquid chromatography (HILIC) and reversed phase chromatography, maximizing coverage of the metabolome.
The technique provides a hypothesis-free description of metabolic differences between samples caused by different genotypes or any perturbations of the system, usually detecting more than 1,000 distinct small molecules. Many of them will be identified with high confidence by our steadily growing in-house library containing more than 500 compounds. Another subset of the detected compounds will be identified by searching public databases.
EQUIPMENT
We currently operate two HPLC-coupled TSQ Altis (Thermo Fisher Scientific). The TSQ Altis is a state-of-the-art triple quadrupole mass spectrometer, optimal for the targeted analysis of small molecules. Metabolites are separated on a bioinert Vanquish (Thermo Fisher Scientific) HPLC system, on-line coupled via electrospray ionization to the mass spectrometer.
We also operate one TSQ Quantiva (Thermo Fisher Scientific) MS system, which is a robust triple quadrupole mass spectrometer used for LC-MS/MS-based targeted analysis. This system is connected to a bioinert Ultimate 3000 HPLC system (Dionex; Thermo Fisher Scientific).
The Q-Exactive (Thermo Fisher Scientific) is a high-resolution instrument, mainly used for metabolite profiling and analysis of lipids. The mass spectrometer is on-line coupled to an inert Ultimate 3000 HPLC (Dionex; Thermo Fisher Scientific).
USER INFORMATION
In general, we offer four types of access to our shared research infrastructure:
- Research projects
- Full research services
- Trained user access | user labs
- Shared technology platform
Typically, these are set but not limited by the offered technology or instrument, and differ in the required user expertise, the usability of a technology, the user’s pre- and postprocessing input, and the underlying operational models.
Research project
Research projects are the equivalent of contract research organizations (CRO). The customer submits the starting material/sample and receives the ready-to-use data for publication. Hence, core facility members are often co-authoring and involved in the entire publication process.
Full research service
The user submits the sample, we perform a pre-defined workflow (incl. QC) and process the raw data. Data interpretation or contributions to publications cannot be offered in this service mode.
Trained user access | User labs
VBCF experts maintain an instrument park and train users to operate it. This requires a certain level of expertise, maturity of the offered technology, a hands-on attitude and reliability from the user.
Shared technology platform | Instrument park
These technologies require expert knowledge to run the offered instruments. Experts are hired by one of the research institutes on the Vienna BioCenter Campus. The experts maintain an instrument park, run the experiments and train other trainers. Machines can only be operated by experts.
The VBCF Metabolomics facility can be accessed via research projects and provides full research service.
In general, the VBCF General Cooperation Conditions apply. To get started, please contact Thomas Köcher to discuss your project and the analytical question you have, especially if you want to start a new project. Please label samples properly and send a sample information sheet via Email along with the samples. Samples can be submitted as extracts, preferentially shipped on dry ice.
