The permeability properties of control artificial lipidic membranes containing synthetic lipids were compared with those made with the lipids and hydrophobic proteins(i.e. proteolipids) extracted from electroplax of Electrophorus electricus and cat heart ventricle. While the controls did not show ionic selectivity the others showed a cationic conductance for Na+ and K+ giving rise to a diffusion potential, which was inhibited by 10-4Md-tubocurarine. It is suggested that proteolipids are responsible for this cationic conductance.
