Kurzbeschreibung
State of the art patch-clamp set-up composed of an EPC 10 USB amplifier (HEKA, Germany), pneumatic anti-vibrating table, piezoelectric micromanipulator (Scientifica), inverted phase contrast microscope (Motic AE31) equipped with epi-fluorescence and FITC and TRITC emission filters for identification of transfected cells, perfusion system with ALA VC4 valve commander and vacuum pump, Macintosh computer running the PatchMaster acquisition software. Users will have access to a horizontal puller (Sutter Instruments) and a microforge (Narishige) for construction of electrodes and to a biosafety level II cell culture room.

Methoden & Expertise zur Forschungsinfrastruktur
Patch-clamp recordings of currents of chloride, sodium, calcium or potassium ions on mam-malian cells, mainly in whole-cell configuration. In principle, also single-channel recordings are possible.
