Patchliner data and applications:
Cells were kindly provided by Cellular Dynamics.
Activation of GABAA receptor currents by 30 μM GABA and partial block of the current response by 1 μM bicuculline. Bicuculline was pre-applied for at least 30 s before co-application with GABA (30 μM). Approximately 50% of the current was blocked by 1 μM bicuculline.
A Voltage-gated K+ current recorded in iCell® neurons. Current responses to a voltage step protocol. An outward K+ current can be seen in this cell.
B Corresponding IV plot from an average of 7 cells.
A Block of Na+ current by increasing concentrations of TTX. Current was blocked by low nM concentrations of TTX indicating a TTX sensitive Na+ channel type expressed in this cell.
B Concentration response curve for TTX inhibition, IC50 = 4.9 nM (n =1).
Voltage-gated Na+ current recorded in iCell® Neurons. Current responses to a voltage step protocol.
A large inward Na+ current can be seen in this cell with a K+ outward current present at positive voltages.
B Normalised IV plot from an average of 4 cells.
11.11.2011 | Nanion successfully performs automated patch clamp recordings from stem cell-derived neurons
MUNICH, GERMANY, November 11, 2011 -- Human iPS cell-derived neurons (iCell neurons) from Cellular Dynamics International were successfully used on Nanion’s 8-channel Patchliner.
To our knowledge, this is the first time stem cell derived neurons have been used on an automated patch clamp device.
Inhibition of NaV1.5 currents in stem cell-derived cardiomyocytes (iCells) by lidocaine. Lidocaine concentrations: 6 µM, 62 µM and 620 µM. The obatined IC50 -value was 14 µM.
Patchliner data and applications:
The stem cell-derived cardiomyocytes (iCell) were kindly supplied by Cellular Dynamics.
In this example both Na+ and Ca2+ mediate the action potential. When nifedipine is applied in the current clamp mode, the action potential is shortened significantly due to block of the calcium channels.
The CardioExcyte 96 allows for
• Non-invasive, label-free measurements of beating cardiomyocyte networks
• 96 recording wells in parallel with 1 ms time resolution
• Quick experiments or long-term compound effects on cardiotoxicity
• Real-time access to beating parameters
• Outstanding software for data analysis and export
• Cost effcient consumables - 96-well format
Effect of the specific hERG blocker, E4031, on the impedance and EFP signals. A Impedance signal of 12 wells in control conditions (left) and the same 12 wells after 13 mins incubation in E4031 at the concentrations indicated (right). E4031 (300 nM, 3 mins incubation) induces EAD, shown in the inset, which can lead to potentially fatal ventricular arrhythmias. B EFP signal of 12 wells in control conditions (left) and the same 12 wells after 13 mins incubation in E4031 at the concentrations indicated (right). E4031(300 nM, 30 mins incubation) also causes arrhythmic effects in the EFP mode shown in the inset.
Cardiomyocytes - Effect of the ß-adrenergic receptor agonist, Isoproterenol, on the impedance and EFP signals on iCells
A Impedance signal of 12 wells in control conditions (left) and the same 12 wells after 13 mins incubation in isoproterenol at the concentrations indicated. Isoproterenol acts as a heart stimulant, it increases heart rate, an effect which is highlighted in the inset where the trace in the presence of isoproterenol (300 nM; black) and the control trace (red) are shown overlaid. In the presence of even low concentrations of isoproterenol (1 nM), an increase in the beat rate is observed. B Bar graph showing beat rate before (dark blue) and after (light blue) incubation in isoproterenol at the concentrations indicated. At all concentrations, a clear increase in beat rate is observed. C EFP signal of 12 wells in control conditions (left) and the same 12 wells after 30 mins incubation in isoproterenol at the concentrations indicated (right). Isoproterenol shortens the FPD, an effect which is highlighted in the inset where the trace in the presence of isoproterenol (300 nM; black) and the control trace (red) are shown overlaid.
