Clinical Proteomics Lab

"Our team attempts to describe molecular mechanisms of human diseases and identify novel diagnostic or prognostic biomarkers."


- Identification of proteins from gels and solutions (MS and MS / MS)

- Proteomic analyzes of complex samples

- Marking and quantitative proteomic analysis of iTRAQ, SILAC etc.

- Proteomic analysis of cells and tissues of all types using iTRAQ, TMT or SILAC isotope methods

- Proteomic analysis of integral membrane proteins

- Training and service in the field of two-dimensional electrophoresis and other proteomics techniques


- The lab is equipped with a Bruker MALDI TOF-TOF AutoFlex Mass Spectrometer.

- The device is primarily used to identify proteins after single-dimensional and two-dimensional electrophoresis, as well as for profiling small proteins and peptides in body fluids.

- In combination with nano-HPLC and the MALDI robotic fraction collector, the mass spectrometer is used for shot-gun proteomic analysis of complex samples, most commonly using quantitative iTRAQ or SILAC labels.

Research Areas

Proteome is defined as the complete set o proteins present at a given time in organism, tissue or cell. Proteomics aim at quantitative and qualitative description of proteomes and their dynamic changes.

Using the most advanced proteomic methods based on effective separation methods and high-resolution mass spectrometry, identification and quantification of up to 10.000 proteins can be accomplished in a single experiment. This opens a new way toward understanding of physiological and pathological processes on molecular level.

Employing proteomic approaches (based on effective protein and peptide separation methods and mass spectrometry) our team attempts to describe molecular mechanisms of human diseases and identify novel diagnostic or prognostic biomarkers.
