Photograph of the lenght standard placed in the hole where bilayer lipid membranes are formed. This reference makes possible area measurement of a bilayer part of the membranes. It is necessary for calculation of specific capacitance of the membranes. This hole has diameter about 1 mm. | |
An example of membrane made of phoshatidylcholine dissolved in n-octane, electrolyte 0.1M KCl. A bilayer is present only in a middle part of the membrane. Border of the membrane contains bubbles of gas. This membrane is unuseful for further experiments. | |
Membrane made of phosphatidylcholine dissolved in n-decane, electrolyte 0.1M KCl. The bilayer occupies small part of the hole, the Plateau-Gibbs border is large. This membrane is little useful for further experiments. | |
Membrane made of phosphatidylcholine dissolved in n-decane, electrolyte 0.1M KCl, 10-5M chlorpromazine. The bilayer contains inclusions of the forming solutions in a form of islands. This membrane is little useful for experiments. | |
Membrane made of phosphatidylcholine dissolved in n-decane, electrolyte 0.1M KCl. This membrane has bilayer of large area. This membrane is stable and useful for any experiments. | |
