Laboratory of biomarkers

Biomarker is a specific indicator which serves for monitoring of physiological/pathological process. Various biomolecules could act as biomarkers, but before that their role needs to be carefully and rigorously devalued. For that we are use the golden standard analytical techniques such as Gas chromatography (GC), High performance liquid chromatography (HPLC) or Mass Spectrometry (MS). Very important is also near cooperation with clinical coworkers. The mission of laboratory is research in veterinary and human medicine.
