PatchControl mini
PatchContol mini: the intuitive Software of the Port-a-Patch mini
The PatchControl mini is a software based on the well-known PatchControl software of the Port-a-Patch and optimized for the Port-a-Patch mini allowing the easiest way to perform your sealing procedure. Equipped with a set of pre-written protocols fitting most user scenarios to obtain a fully automated procedure to rech whole cell configuration, the protocols can also be altered, allowing the entire procedure for cell capture, sealing and obtaining the whole cell configuration to be completely customizable. However, because we know that sometimes you just want to control things yourself, the protocols can be interrupted at any time and the suction controlled manually.
Through innovative communication with the electrophysiology software WinWCP, PatchControl mini can read out important parameters like membrane resistance, whole cell capacitance and series resistance and uses those to perform the pre-programmed automated steps accordingly. Suction strength and duration, voltage and membrane criteria can be set and altered to obtain the optimum parameters for cells routinely used in your lab.
The PatchControl mini software is there to make your patch clamp life easier, from automated cell capture to automated pressure control, the PatchControl mini software can do it all!

データ＆アプリケーション
Astrocytes - Current Traces of Potassium Channels
Port-a-Patch mini data and applications:
Native mouse Astrocytes.
Patch clamp recordings from cultured mouse primary astrocytes were made in the whole cell configuration. Currents of expressed Potassium channels were obtained by depolarizing voltage pulses from a holding potential of −80 mV.
Chondrocytes - Current response to voltage ramp
Port-a-Patch mini data and applications:
Native Bovine Chondrocytes were kindly provided by Dr. Rebecca Lewis, University of Surrey.
Patch clamp recordings from primary chondrocytes were made in the whole cell configuration. The raw current trace was obtained by using a ramp protocol starting from -100 mV to 100 mV.
hERG - Application of Dofetilide
Port-a-Patch mini data and applications:
Cells were kindly provided by SB Drug Discovery.
Raw data traces of hERG (expressed in HEK cells) in control solution and in the presence of increasing concentrations of Dofetilide (top). IC50 concentration response curve for an average of 3 cells is shown revealing an IC50 of 161 ± 12 nM.
NaV-Late - Recorded from Cardiosight-S hiPSC-CMs
Port-a-Patch mini data and applications:
Cells were kindly provided by Nexel.
NaV-Late was induced by application of ATX II in Cardiosight-S® cells on the Port-a-Patch mini. Example traces are shown on the top with the response to the voltage ramp (CiPA protocol) shown in the inset. The timecourse of the experiment is shown on the bottom, with block by ranolazine.

Port-a-Patch mini data and applications:
Cells were kindly provided by Charles River.
The image shows currents from an example cell and the corresponding current-voltage plot for NaV1.5 expressed in stably-transfected CHO-K1 cells.
NaV1.5 - Tetracaine concentration response curve
Port-a-Patch mini data and applications:
Cells were kindly provided by Charles River.
The image shows the timecourse of the experiment (top) where peak amplitude is plotted against time and example traces in control conditions and different concentrations of tetracaine are also shown in the insert. The concentration reponse curve for tetracaine is shown on the bottom for an average of 6 cells. The curve is fit with a Hill equation revealing an IC50 = 25.5 ± 5.7 µM (n = 6).
インタビュー&ケーススタディー
Martin Sumser - Statement about the Port-a-Patch mini
"One afternoon is all I needed to get familiar with the features and perform measurements. As an electrophysiologist and university lecturer, I see the Port-a-Patch mini as a great tool to introduce patch clamp to young university students, but also post-doc level scientists in need of a fast, high quality electrophysoplogy data."

Bernhard Stenger - Statement about the Port-a-Patch mini
„The new Port-a-Patch mini combines a small and easy set-up with an intuitive software and enabled us to generate data with minimal effort. With the help of a video tutorial we were able to record the effect of AITC on TRPA1 within an hour after setting up the system. This device can be a great tool for testing the effect of compounds on ion channels with the patch clamp technique without spending a lot of time with preparation like priming tubes or pulling pipettes. Especially the possibility of using small volumes (5-15µl) as internal and external solution are an advantage when handling rare and/or toxic substances.”
