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