Abstract

Dependence of the distance between contacting bilayer lipid membranes on the concentration of mono-and bivalent cations and medium pH has been measured by an optimcal method. It has been show that the presence of cations in the medium decreases the equilibrium distance between contacting membranes, the effect being more pronounced for bivalent Ca.

摘要

已通过光学方法测量了接触双层脂质膜之间的距离对单价和二价阳离子浓度以及介质pH值的依赖性。结果表明,介质中阳离子的存在会减小接触膜之间的平衡距离,对于二价钙离子,这种效应更为明显。
