Laboratory of Separation and Spectroscopic Method Applications


The main specialty of the Laboratory of Separation and Spectroscopic Method Applications is development, validation and applying of analytical methods for qualitative and quantitative analyses of biologically active substances including small molecules (drugs, metabolites, toxins, pesticides) and proteins. We utilize variety of chromatographic, mass spectrometry and immunochemical methods to understand the role of metabolites in mechanisms of diseases, identify novel therapeutic targets and biomarkers mainly in the field of cancer and metabolic disorders. We also identify food toxins, including pesticides and mycotoxins. Our studies performed in collaboration with the Medical University of Lublin and Institute of Immunology and Experimental Therapy, Polish Academy of Science in Wroclaw focus on the role of glycation and kynurenine pathway on immune response modulation, cancer microenvironment, and human endometrium.

Our interdisciplinary team consists of scientists with competencies in analytical chemistry and biochemistry: Magdalena Staniszewska, PhD, DSc; Ilona Sadok, PhD; Ilona Jonik, MSc.
