摘要: In the last few years fluorescence microscopy has become a very useful technique to study lateral structure of membranes. Several experimental strategies using techniques (epifluorescence, confocal and two-photon excitation) have appeared in literature employing GUVs as model systems. The advantages disadvantages different approaches, including use fluorescent probes, were discussed this chapter. particular, polarity-sensitive probe LAURDAN marker under two-photon-excitation microscope not only artificial lipid mixtures but also natural extracts cell membranes was addressed. visual information obtained with these is extremely correlate compositionally simple that observed complex such biological
