| Description: | Test compounds were serially diluted in DMSO and then resuspended to the final test concentration in external recording solution, with, or without 40 μM acetylcholine added to the external recording solution; test compounds were then transferred to the IonFlux HT population patch plate. Internal recording solution (110 mM TrisPO4, 28 mM TrisBase, 0.1 mM CaCl2, 2 mM MgCl2, 11 mM EGTA, 4 mM MgATP) was added to the internal recording solution inlet wells on the IonFlux HT patch plate previously loaded with cells and test compounds, and the plate loaded into the IonFlux HT instrument. A protocol was executed on the IonFlux HT to trap the cells, break into the cells, and establish the whole-cell recording configuration; cells were voltage-clamped at a holding potential of −60 mV for the duration of the experiment, all experiments were conducted at room temperature, and the IonFlux HT injection pressure was 8 psi for solution applications. |
