Sažetak
Giant unilamellar vesicles are popular model membrane systems in research due to having a size similar to that of eukaryotic cells. Electroformation is the method most commonly used for their production. However, due to a large number of parameters, their values often have to be adjusted when working with new mixtures. Here we used phosphatidylcholine/cholesterol and phosphatidylcholine/sphingomyelin/cholesterol lipid mixtures. Fluorescence and atomic force microscopy were utilized to find the optimal values of electrical parameters and lipid film thicknesses. Special attention was given to the effect of different cholesterol contents, with measurements performed for cholesterol concentrations surpassing the phospholipid bilayer saturation threshold. Such high cholesterol contents are of interest to researchers studying the role of cholesterol in fiber cell plasma membranes of the eye lens or in the development of atherosclerosis. We show that increasing the cholesterol concentration decreases the vesicle size, but this effect can be reduced if appropriate electroformation parameters are chosen.
