Single channel current traces, current transition amplitude histograms,
and lifetime histograms (from left to right) for
1-Me-Trp9[gA] (top) and 1-Me-Trp15[gA]
(bottom). Only a single predominant channel type is observed in
the current transition amplitude and lifetime histograms. Conditions were as
follows: Diphytanoylphosphatidylcholine, 1 m NaCl, 200 mV, 25
°C.
