| Description: | Whole cell currents were measured with HEKA EPC-10 amplifiers using PatchMaster software or by using the high throughput QPatch platform (Sophion). Bath solution for all experiments contained (in mM): NaCl 137 mM, KCl 4 mM, CaCl2 1.8 mM, MgCl 2 1 mM, HEPES 10 mM, D-Glucose 10 mM, pH (NaOH) 7.4. In some cases 0.005% cremophor was also added. Intracellular (pipette) solution contained: KCl 130 mM, MgCl 2 1 mM, Mg-ATP 5 mM, HEPES 10 mM, EGTA 5 mM, pH 7.2. During experiments, cells and solutions were maintained at room temperature (19° C.-30° C.). For manual patch clamp recordings, cell culture dishes were placed on the dish holder of the microscope and continuously perfused (1 ml/min) with bath solution. After formation of a Gigaohm seal between the patch electrodes and the cell (pipette resistance range: 2.5 MΩ-6.0 MΩ; seal resistance range: >1 GΩ) the cell membrane across the pipette tip was ruptured to assure electrical access to the cell interior (whole-cell patch-configuration). For experiments using the QPatch system, cells were transferred as suspension to the QPatch system in the bath solution and automated whole cell recordings were performed. |
