MECA 16 TC chips
The MECA 16 TC recording substrate contains an array of 16 circular microcavities in a highly inert polymer. Each cavity contains an individual integrated Ag/AgCl-microelectrode. The bilayer is automatically formed by remotely actuated painting (Ionera1-SPREAD), thus roofing the liquid-filled cavity. The bilayers can be easily and repeatedly zapped and re-formed in an automated fashion. After bilayer formation, ion channels or nanopores are reconstituted via self-insertion, proteoliposome fusion or dilution from detergent micelles.
The MECA 16 TC 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 16 chips will be available depending on the sample.

数据与应用：
Alpha-Hemolysin - Parallel Recordings of monoPEG-28 Block
Orbit 16 data and applications:
Data courtesy of Dr. Gerhard Baaken et. al., University of Freiburg / Ionera.
Event-averaged histograms (black) and overlaid current traces (blue) of parallel and simultaneous recordings on a MECA chip of monoPEG-28-mediated blockages of hemolysin nanopore(s). The current traces were recorded with a multichannel amplifier (Tecella Jet 16). Histograms were derived from the mean current levels of at least 2000 visits of blocked stated per cavity (20 kHz sample frequency).
