LABORATORY OF PHARMACOKINETICS

About the lab

Laboratory of pharmacokinetics deals with two main fields of scientific research activities. It primary focuses on development of analytical methods and their application to preclinical, or clinical research. The laboratory is equipped with triple quadrupole mass spectrometers which are connected to liquid, or gas chromatograph. Such devices are able to analyse compounds at low concentration levels (ng – pg/mL samples) as well as compounds having a broad spectrum of polarity. Our research mainly focuses on pharmacokinetic and toxicological analyses of drugs and their metabolites in biological samples such as blood, plasma or urine. Analytical methods are approved according to the valid regulations (Guideline on bioanalytical method validation – EMA, Bioanalytical Method Validation – FDA) and subsequently applied in various studies and projects.

Another scientific research activity is targeted at metabolomic analyses of biological samples. Our laboratory has implemented methods via commercially available kits from Biocrates Life Science AG (Austria) company used for metabolomic studies of various biological materials, such as blood, plasma, urine, CSF, cell cultures, or tissues. Using metabolomic analyses, we are able to quantify analytes (metabolites) covering a wide range of biologically important compounds, such as amino acids, biogenic amines, acylcarnitines, glycerophospholipids, sphingomyelins, bile acids (primary and secondary, or conjugated and unconjugated) and steroid hormones – glucorticoids, mineralocorticoids, androgens, estrogens and progesterones.

In addition, we provide assistance and consultation with the initial design of pharmacokinetic and toxicological analyses and the design of metabolomic studies. In cooperation with the Laboratory of Bioinformatics and Biostatistics, we participate in the processing and evaluating the metabolomic data and biological interpretation of the results.

Services

The laboratory also provides services and cooperation on a commercial basis. These mainly include targeted metabolomic analyses using kits from Biocrates company. It is also possible to do quantitative analysis of drugs or other exogenous and endogenous analytes in biological samples (blood, plasma, urine, tissues, cell cultures and others). The main advantage is the possibility to optimize analytical methods upon request (detection limit, sample amount, simultaneous analyses of multiple analytes, etc.). In case of interest or further questions, you can contact us by e-mail: martin.kertys@uniba.sk

Laboratory Infrastructure

Laboratory of Pharmacokinetics is equipped with triple quadrupole mass spectrometer with liquid chromatograph (Xevo TQ-S s Acquity 2D UHPLC, Waters) and with triple quadrupole mass spectrometer with gas chromatograph (Scion TQ a 456 GC, Bruker)

In addition, the laboratory is equipped with other essential devices and instruments, such as an instrument for SPE sample pre-treatment (Positive pressure-96 processor, Waters), vacuum sample concentrator (Concentrator plus, Eppendorf), nitrogen sample concentrator (Minivap Gemini, Porvair) and many others.
