SURFE²R 96SE 装置 & ソフトウェア

The SURFE2R 96SE device

The SURFE2R (surface electrogenic event reader) technology is the only available commercial solution for SSM-based electrophysiology on the market. Nanion Technologies developed the SURFE2R N1 as an easy-to-learn all-in-one device for universities and basic research and the high-throughput device SURFE2R 96SE.

The SURFE2R 96SE is integrated into the CyBio® Felix liquid handling platform. Nanion Technologies provides the electrophysiological hardware and the computer running a software package for data recording and analysis. The device can not only be used for electrophysiological measurements, but also for sample preparation and pipetting purposes. The device can measure 10,000 data points a day in a fully automated manner. In contrast to the SURFE2R N1, the SURFE2R 96SE also comes with a dedicated data analysis software which allows for automated analysis of the massive amount of data you generate each day.

The SURFE2R 96SE uses sensors in a standard 96-well plate format. Membranes containing the protein of interest are adsorbed onto these sensors. The measurement is initiated by a substrate concentration jump. The solution exchange is controlled by the liquid handling platform CyBio® Felix. The pipetting head contains 96 pipettes which load solutions from solution positions and inject them to the sensor plate. All 96 sensors of the sensor plate are measured simultaneously, but different solutions or transporters can be used for each measurement.

The sensor plate is enclosed by a Faraday cage and connected to a 96-channel amplifier as well as 96 gold pins which work as reference electrodes. The CyBio® Felix holds up to 8 well plates for 8 to 8 x 96 different solutions which allows up to 7 sequential measurements using different conditions in each automated workflow. The CyBio® pipettor allows the measurement of fast kinetics with low solution consumption, showing a time resolution of down to 5 ms by using only 50 µl of compound solution per measurement.
Software Package

Our software department developed a software package exclusively for the SURFE2R 96SE.

• The SurfControl works as the recording software and displays the data in real-time
• DataControl works as the analysis software and can be configured to automate your data analysis
• In addition, the CyBio Composer plus pre-installed workflows operate the liquid handling platform and
communicates with the recording software

インタビュー & ケーススタディ

Analytik Jena - Maria Barthmes about the Cooperation on the SURFE²R Technology

Dr. Thomas Seeger & Karin V. Niessen - Statement about the SURFE²R Technology

Icon N1   “The SURFE²R makes extremely challenging electrophysiological targets accessible to robust routine analyses. For example, we have developed an assay for investigating nicotinic acetylcholine receptor ion channels, using membranes from the Pacific electric ray, Torpedo California. In this way, we overcome many of the well-known difficulties associated with this ion channel, which allows us to efficiently obtain information regarding compound pharmacology. Obtained pharmacology values match those of patch clamp recordings exceptionally well. We find that the SURFE²R is an excellent platform for characterization of electrogenic processes in isolated membranes.”

Karin V. Niessen, Dr. Thomas Seeger
Bundeswehr Institute of Pharmacology and Toxicology, Munich, Germany

Prof. Dr. Klaus Fendler and Co-Authors - Interview about the SURFE²R Technology

Icon N1   ““SSM-based electrophysiology is a suitable technique to study bacterial ion-translocating membrane- systems which are otherwise difficult to approach using conventional electrophysiological techniques, like patch clamp.
Additionally, the mechanical stability of SSMs facilitates the transport activation through fast solution exchange, a condition that is technically challenging in a setup of a bilayer separating two solution-containing compartments.“

Dr. Miyer Fabián Patiño-Ruiz,
Faculty of Science and Engineering, University of Groningen, the Netherlands

Prof. Dr. Randy Stockbridge - Interview about the SURFE²R Technology

Icon N1   “We wanted to characterize the electrophysiological characteristics of our new family of transporters to find out properties such as Km and Vmax of the substrate, and ideally to screen a set of substrates for transporter activity. However, given our difficulties in developing a transport assay, I was pessimistic that we were going to be able to move beyond radiolabeled substrates.
Contrary to my expectations, electrophysiology with the SURFE²R N1 platform worked right away. We saw very robust currents in our pilot experiments during the initial training session on the instrument.“

データ & アプリケーション

EAAT3 - Screening of 6 inhibitors

EAAT3 Surfe2r96SE data

Icon 96SE   SURFE2R 96SE data and applications:

Screening of 6 inhibitors for EAAT3. After negative control and full activation of the transporter, different concentrations of inhibitor were used. At the end the full activation was repeated.



NCX1 - High Throughput Screening on the SURFE2R 96SE


Icon N1   SURFE2R 96SE data and applications:
Cells were kindly provided by Charles River.

NCX1 over-expressed in HEK cells was recorded on the SURFE2R 96SE. A membrane preparation of HEK cells expressing NCX1 was used on the SURFE2R 96SE. An activating buffer containing 100 μM Ca2+ was used to activate NCX1 (black and dark blue traces) after a negative control (0 Ca2+; light blue trace). NCX1 was activated three times after which a pharmacological experiment can be started to test for inhibitors. Wells are color-coded so that the user can get an overview of the succes of the experiment at a glance. Green wells depict resistance >500 MΩ, blue depicts wells have a resistance between 100 and 500 MΩ.
