Abstract

We study the effect of permeabilizing electric fields applied to two different types of giant unilamellar vesicles, the first formed from EggPC lipids and the second formed from DOPC lipids. Experiments on vesicles of both lipid types show a decrease in vesicle radius, which is interpreted as being due to lipid loss during the permeabilization process. We show that the decrease in size can be qualitatively explained as a loss of lipid area, which is proportional to the area of the vesicle that is permeabilized. Three possible modes of membrane loss were directly observed: pore formation, vesicle formation, and tubule formation.

摘要

我们研究了施加于两种不同类型的巨型单层囊泡的通透电场的影响,第一种由蛋黄卵磷脂(EggPC)脂质形成,第二种由二油酰磷脂酰胆碱(DOPC)脂质形成。对这两种脂质类型的囊泡进行的实验均显示囊泡半径减小,这被解释为是由于通透过程中脂质损失所致。我们表明,尺寸的减小可以定性地解释为脂质面积的损失,其与被通透的囊泡面积成比例。直接观察到了三种可能的膜损失模式:孔形成、囊泡形成和小管形成。
