Figure 1

The representation of a bio-channel in PNP theory. Shown is a central slice through the YZ plane of the AHL channel. The light and dark blue together represent the solvent, characterized by the high dielectric media; green represents the low dielectric media of the membrane; pink represents low dielectric media. Protein is shown mainly in pink. Red and blue dots show negative and positive partial charges of the protein atoms; dark blue shows the ion accessible volume. Cis- and trans- compartments are located above and below the membrane respectively.
