Democritus University of Thrace

The Department of Molecular Biology & Genetics (MBG) of the Democritus University of Thrace (DUTH) has been operating since 2000 and it is the only Department in Greece that provides studies in Molecular Biology and Genetics. MBG has extensive experience in the fields of Biomedicine, Molecular Biotechnology, Agrobiology and Nutrition. In addition, MBG collaborates with industries, and participates and co-finaced by European Union.

As a member of OPENSCREEN-GR, the MBG / DUTH offers the know-how and services for toxicity and function evaluation of bioactive molecules and chemical compounds, aiming to initial characterise and evaluate biological activity, which will lead to possible guiding molecules for further investigation into molecular targeting studies and new therapeutic approaches.

More specifically, services offered for analysis of toxicity profiles in cell systems, characterization of various biological actions in vitro, such as antioxidant, antiproliferative / anti-cancer, anti-inflammatory or anti-microbial action, as well as chemical microbial products & natural microbial products.

Services

Flow Cytometry

The unit is equipped with Attune NxT acoustic flow cytometer (Thermo Fischer Scientific) and the Attune NxT Software. The flow cytometer has two lasers: 488 nm, 50 mW (blue) and 637 nm (100 mW) which allow the retrieval of up to nine different parameters, up to seven color fluorescence data plus front and side scattering. Acoustic focus technology allows the analysis of up to 35,000 events per second.
