SURFE²R 96SE - 高通量转运体研究设备

与 SURFE²R N1一样,SURFE²R 96SE基于固体支撑膜(SSM)电生理技术,解决转运体与离子泵电流过小的问题,同时将通量提高到平行进行96个记录。只需要将转运体样品加到96孔记录板镀金电极上。并且为了进一步减少用户的工作量,所有电极预处理步骤都由SURFE²R 96SE自动完成。并且可以加任何底物都可以加入激活转运体,且会记录相应的转运或绑定电流。所有的以上步骤,从制备样品、测定到数据分析都是自动进行的。

SURFE²R 96SE 设备与软件

The SURFE2R 96SE 设备


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.

用户评价与案例分析

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.”
