✦ Synopsis

Measurements have been made of the optical reflectance of egg lecithin-cholesterol bilayers and a value of 64 ± 4 ,~ obtained for the bilayer thickness. There is some evidence that Ca ++ binds to the bilayer when the ion concentration in the aqueous phase is greater than 2M. These results are compared with those obtained for egg lecithin bilayers in the absence of cholesterol.
