Methods and Technologies

Beside expertise in the fields of molecular biology, biochemistry and cell biology, the research groups participating in the graduate school provide a large variety of methods and strategies to study Ca2+-signals and their functional consequences with high temporal and spatial resolution:




  • Measurement and control of intracellular Ca2+-signals: high resolution calcium-imaging and ultra-fast UV-flash photolysis of caged compounds


  • Imaging techniques: Bioluminescence resonance energy transfer, laser scanning and real-time confocal microscopy, 2-photon microscopy, Time-Lapse video microscopy, Total-Internal-Reflection-Fluorecence microscopy (TIRF).


  • Electrophysiology and measurements of secretion at the level of single cells and single vesicles: Patch clamp technique, high-resolution membrane capacitance measurements, carbon fiber amperometry, electrical measurements of exocytotic fusion pores, elektroenzephalo- und electrocorticograms.


  • Analyses of cellular ultrastructure: Transmission- und Scanning electron microscopy


  • Protein-Protein-Interactions in-vitro and in-vivo: Biochemical methods, Multi-angle light scattering (MALS), Plasmon-resonance-transfer (BIAcore), Yeast-Two Hybrid system, Fluorescence energy transfer (FRET)


  • Techniques for purification of recombinant and native proteins


  • Protein structure analyses: X-ray cristallography


  • Viral vector constructs and siRNA-technology: Gene transfer with Semliki-Forest, Adeno- und Lenti-Viruses into primary cells


  • Quantitative single cell PCR


  • Transgenic mouse technology


  • Flow-through-cytometry & Fluorescent Associated Cell Sorting (FACS)


  • Specific cell cultures: Primary cultures of neurons, chromaffin cells, endothelial cells, mast cells, cardiomyocytes, pancreatic beta-cells, T-lymphocytes, organotypic cultures of retina


  • Pharmacological tests, receptor binding studies


  • Mouse behavioral testing
