(0.43 MB)
The MECA 4 OPTO-technology enables simultaneous optical and electrical recordings in free standing artificial lipid bilayers.
The MECA 4 OPTO-INV kit is comprised of an adapted Faraday shield for Nanion‘s Orbit mini bilayer recording station and a tailor-made holder for Ionera‘s MECA 4 OPTO-INV chips.
The holder allows for the positioning of the recording chips over the objective of an inverse microscope while enabling the electrical connection between the chips and the amplifier inside the Orbit mini.

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)
用户评价与案例分析
Prof. Dan Burden - MECA 4 OPTO-INV
"The MECA OPTO system easily coupled to my inverted microscopes and worked with a wide range of objectives. The MECA OPTO-holder provides traditional convenient bilayer formation and channel insertion with good electrical noise characteristics while markings make locating microwells quick and easy. Simultaneous optical and electrical interrogation of the microwell aperture accelerates lipid bilayer validation for ion channel measurements.

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.
