Permeabilization of mercury-supported biomimetic membranes by amphotericin B and the role of calcium ions

- Ca2+ ions favor ion channel formation in sterol-containing biomimetic membranes.
- Low AmB concentrations disrupt sterol-free mercury-supported DOPC monolayers.
- Channels formed by AmB-Erg complexes are stable under physiological conditions.
- Channels formed by AmB-Chol complexes are unstable under physiological conditions.
