KcsA - Single Channel Recordings
Orbit 16 and applications:
Data were kindly provided by Ionera.
Single channel currents of tetrameric potassium channel KcsA E71A recorded from 5 selected bilayers in parallel.
KcsA was expressed in vitro with its co-translational integration into liposoms containing asolectin lipids. The proteoliposomes were subsecuently fused with bilayer array containing POPE/POPG on the Orbit 16.
Conditions: Current traces were recorded in 20 mM MES pH 4.0 on the cis-side and 10 mM MOPS, pH 7.0 on the trans-side of the bilayer; containing 200 mM KCl symmetric solutions with membrane potential held at +150 mV.
