In the earlier experiments it was established that a bilayer of pure egg phosphatidyl choline containing less than 50 per cent by volume of n-decane had a capacitance of 0.38 /ff/cm2 , this value being independent of applied voltage up to at least 50 my and independent of frequency between 200 and 5 X 106 cs. It was also unaffected by the nature and concentration of the surrounding electrolyte ...
