Laboratory of Metabolomics offers targeted and non-targeted metabolomics analysis using highly specialized instruments, including a combination of a liquid chromatograph with a mass spectrometer (with an accuracy of 0.0001 Da) and a 600 MHz NMR spectrometer.
Cell metabolism is an essential feature of life and results in the formation of metabolites in a living organism. Analysis of their concentration changes is one of the basic diagnostic tool of modern medicine. Laboratory of Metabolomics offers targeted and non-targeted metabolomics analysis using highly specialized instruments, including a mass spectrometer (with an accuracy of 0.0001 Da) and a 600 MHz NMR spectrometer. We focus mainly on metabolic analyses of low molecular weight substances in tissues, cell cultures and biological fluids (blood plasma, urine, cerebrospinal fluid, tissue extracts, cell media and lysates).
The lab is also equipped with an experimental 7 Tesla scanner based on magnetic resonance enabling non-invasive imaging (MRI) of biological systems but also other types of samples. Imaging sequences allow the monitoring of a wide range of in vivo, ex vivo and in vitro processes and are also suitable for functionalized therapy monitoring using magnetic nanoparticles (theranostics). In addition, using spectroscopic methods (MRS), we can monitor biochemical profiles of the examined tissues, including dynamic pharmacological and metabolic processes in vivo.
