Gramicidin - Single Channel Analysis
Port-a-Patch and 
Vesicle Prep Pro data and applications:
Recordings were kindly supplied by Tohoku University, Tohoku, Japan.
Plotting the current amplitude vs. the voltage reveals conductances of 94.88 pS and 28.28 pS, which correspond to two different gramicidin derivates present in the bilayer. Traces were recorded in 100 mM HCl at the indicated potentials. Clearly two gramicidin derivates (94.88 pS and 28.28 pS) can be distinguished.
