The laboratory was established in cooperation between the staff of the Department of Pharmaceutical Pathophysiology and the Department of Clinical Biochemistry. Our scientific work includes experimental nanomedicine, platelet pharmacology, studies of platelet interaction with tumor cells, and the role of thrombocytes in the process of metastasis. We offer the possibility of performing experiments or providing substantive support for your ongoing projects. Our scientific activities involve the following methods: eukaryotic cell culture, including organoids; assessment of substance cytotoxicity; Western blot technique; PCR; ELISA; flow cytometry, fluorescence microscopy, light aggregometry. We also have experience in obtaining funding from external sources. We collaborate with research teams from home and abroad:

Division of Molecular Medicine

The Division of Molecular Medicine deals with analyses of pathomechanisms that underlie various diseases, at the molecular level. We are working on understanding the molecular basis of various disease entities, in vitro, ex vivo, as well as in vivo, therefore we have developed close cooperation with Colleagues from various Departments and Clinics of our University. Our scientific activities involve the following techniques: isolation of various types of nucleic acids from biological specimens; determination of polymorphisms, mutations of selected genes – real-time PCR; assessment of gene expression levels – real-time RT-PCR;qualitative and quantitative analysis of microRNAs – real-time RT-PCR; cell culture (cell lines and primary lines); cytotoxicity assessment of selected compounds: MTT, LDH, AP; protein assessment: ELISA, Western blot, immunofluorescence; overexpression or silencing of gene expression by shRNA using a lentivirus system. In terms of the foregoing molecular methods: we offer both substantive support and performing experiments.

System PCR w czasie rzeczywistym LightCycler® 480 Roche

The LightCycler® 480 Instrument II is a high-speed, 96-well plate-based cycler with integrated real-time on-line detection capabilities. The special arrangement of optical elements in the LightCycler® 480 Instrument II ensures uniform collection of signals on the plate, and makes the analysis independent of sample position on the plate.

The LightCycler® 480 system configuration allows using all current probe formats (e.g., SYBR Green I, ResoLight high-resolution melt dye, hydrolysis probes, HybProbe probes, SimpleProbe probes), providing a solution for rapid and precise qualitative or quantitative detection of nucleic acids, genotyping and mutation scanning. Channels and filters can be combined in a variety of ways to provide flexibility for mono-color and multiplex testing. The pre-installed LightCycler® 480 software provides an intuitive, easy-to-use user interface for real-time PCR reaction programming, data storage and analysis. It facilitates highly comprehensive and extensive data analysis to study gene expression and genetic variation

BSL-2 microbiology laboratory

In addition, we have a separate microbiology lab, also with infrastructure for cell culture, where you can safely work with bacterial or viral systems for precisely increasing or silencing the expression of the studied genes.
