Mean currents measured upon insertion of single α-HL channels into BLMs.a,b

Lipid Mean Current Before Insertion (pA) Mean Open Current After Insertion (pA) Difference Current (pA)
DPhPC (n = 5) −0.2 ± 0.4 −41.2 ± 0.4 −41.0 ± 0.6
bis-DenPC (n = 5) −0.2 ± 0.4 −41.2 ± 0.4 −41.0 ± 0.6
bis-SorbPC (n = 5) −2± 1 −42 ± 1 −40 ± 1
mono-DenPC (n = 5) 3 ± 3 −39 ± 4 −42 ± 5
mono-SorbPC (n = 5) −2 ± 1 −41 ± 2 −39 ± 2
a

Five trials were conducted for each lipid composition. In each trial, the mean current was measured for one minute before insertion and for one minute after insertion.

b

BLMs were not irradiated. Note that α-HL channels do not insert into BLMs composed of polymerizable lipids after they have been irradiated.
