    • The line tension at the edge of the mixed composition bilayer can be expected to influence the shape of the intercalated lipid phase. In the present case, high cholesterol and sphingomyelin concentrations must impart some liquid-ordered or gellike character. We further note that the minimization of line tension in supported membranes was previously observed to be very slow, presumably because of factional coupling with the substrate.

    • note
    • Note the presence of some extended structures in the fluorescence morphology. They were observed only in some bilayers formed by the rupture and spreading of SUVs derived using raft-forming lipid mixtures. We do not fully understand the origin of these structures but conjecture the deposition of occasional unfused vesicles.
