MECA 4 记录芯片
The MECA recording substrate contains a 2 x 2 array of circular microcavities in a highly inert polymer. Each cavity contains an individual integrated Ag/AgCl-microelectrode. The bilayer is formed by painting, with high success rates for functional bilayers. The MECA chip has been validated with a number of different ion channels including KcsA, gramicidin, α-hemolysin, KV1.3, NaV and many more.
The MECA recording chips are produced and quality assured by our partner Ionera Technologies GmbH in Freiburg Germany and shipped from Munich to our international customers. Different types of MECA recording chips are available which should be chosen depending on experiment.
Available chip types
- "Meca 4 Recording Chips 50 µm": Four-well recording chip with 50 µm cavity size (Order # 132001)
- "Meca 4 Recording Chips 100 µm": Four-well recording chip with 100 µm cavity size (Order # 132002)
- "Meca 4 Recording Chips 150 µm": Four-well recording chip with 150 µm cavity size (Order # 132003)
- "Meca 4 Recording Chips Fluo": Four-well recording chip for fluorescence applications with 150 µm cavity size (Order # 132004)

Prof. Dr. Chris Miller - Case Study about the Orbit mini
"Contrary to my initial expectations, the Orbit mini (red arrow) has performed exceptionally well for
our application, with vastly improved signal-tonoise characteristics over our best recordings on the home-built system."
“The compactness of the instrument makes for flexible and convenient placement in the lab. With a tiny footprint, it sits on a table or desk accompanied by only a laptop. In addition, bilayers are painted 'blind' with a teflon wand supplied by Nanion without observing the partition through a microscope. Thus, the
entire support-package of microscope, illuminator, Faraday cage, vibration-table, and rig-rack is eliminated. The acquisition software is intuitive and robust, and the data can be stored in formats readable by the Axon analysis programs that we routinely use. Moreover, the four electrically independent holes in the chip-partition means that four bilayers can be monitored simultaneously, thus quadrupling the probability of catching a clean single channel to record. This represents a significant, practical boost in experimental efficiency.”

Orbit 16 and Orbit Mini
This webinar covers the use of the lipid bilayer platforms from Nanion: the Orbit16 and the Orbit mini for characterization of membrane proteins like ion channels, bacterial porins and biological nanopores. Both bilayer systems support high quality low noise recordings, but differ in throughput capabilities and experimental features. The Orbit16, introduced in 2012 is a device for efficient formation of 16 lipid bilayers simultaneously, allowing for parallel bilayer-reconstitution of ion channels and nanopores.
