Core facility (CF)

Short Description

The Core Facility Biomolecular & Cellular Analysis (BmCA) offers state-of-the-art instruments and techniques for characterization of biomolecules and/or biomolecular interactions. Another focus lies on the analysis and sorting of cells and cellular components by flowcytometry. Additionally, the lab is equipped with high-end instrumentation for protein crystallography do determine 3D structures of proteins and protein-ligand complexes.

Methods & Expertise for Research Infrastructure

The Core Facility Biomolecular & Cellular Analysis (BmCA) is a state-of-the-art analytical laboratory with focus on biomolecular characterization and characterization of biomolecular interactions, protein crystallography as well as flowcytometry. Beside high-end instrumentation, we offer the possibility to prepare your samples in the most optimal way. We have basic laboratory equipment (pipettes, multi-channel pipettes, dispenser pipettes, coolable centrifuge, vacuum filtration, analytical balances, pH electrodes of different sizes, water bath, DeNovix instrument for UV-vis absorption and fluorescence measurement etc.). Further, we offer two PC work stations which are accessible for all Core Facility users to utilize the partly licencesed special software of the various instruments. Besides providing instruments, we offer professional training to the certain techniques as well as consultation regarding experimental setup and design. Further, it is possible to make use of our full-service, which comprises the measurements of your samples by trained staff and the generation of experimental reports.
