Then, DOPH at low ion concentration ( like oil-drop ) shows high resistance between membranes ( more than several mega Ω ).
Meanwhile, DOPH at high ion concentration has low resistance between membranes ( hundreds kΩ ).
Accordingly, the same as nervous membrane, the produced lipid membrane gets to be put in a state with two different membranous resistances.
Next, a DOPH-membrane was put in the gap between the solution of potassium chloride of 1 milimole
and that of 100 mmol, the water-pressure of 30 cm was added to the membrane from the side of 100 mmol, and a direct current was applied to that.
Then, the membranous electric potential was measured.
※ mmol ＝ 1/1000 of mol
