“…The monolayer parameters are in good accord with those in previous studies [40,41]. Furthermore, DStPC formed an LE monolayer, which is also consistent with the fact that DStPC forms only LE monolayers at 4-25 • C [23].…”

“…When first considering conformations for Group I lipids, previous reports [34,35] on StA monolayer are very suggestive. Its monolayer behavior at large areas has been well explained by the presence of non-upright conformations of lipids [34][35][36]40], where both two polar parts of a chain, i.e., for Group I lipids, both a triple bond and a carboxyl group (or an ester group for PCs), are immersed in the subphase (Fig. 7left).…”

“…During this compression, a transition from the gaseous state (surface pressure equals zero) to the liquid expanded state occurs. This small increase in the surface pressure represents the beginning of observable intermolecular forces between adjacent molecules in the monolayer [31,32]. The area over which this increase occurs defines the limiting molecular area.…”

Abbreviations used:  diff -potassium diffusion potential,  S -surface potential; DP -degree of polymerization; ODA -octadecylamine; polySia -polysialic acid; OX-Voxonol V, TB -toluidine blue Abstract: Polysialic acids are linear polysaccharides composed of sialic acid monomers. These polyanionic chains are usually membrane-bound, and are expressed on the surfaces of neural, tumor and neuroinvasive bacterial cells. We used toluidine blue spectroscopy, the Langmuir monolayer technique and fluorescence spectroscopy to study the effects of membrane surface potential and transmembrane potential on the binding of polysialic acids to lipid bilayers and monolayers. Polysialic acid free in solution was added to the bathing solution to assess the metachromatic shift in the absorption spectra of toluidine blue, the temperature dependence of the fluorescence anisotropy of DPH in liposomes, the limiting molecular area in lipid monolayers, and the fluorescence spectroscopy of oxonol V in liposomes. Our results show that both a positive surface potential and a positive transmembrane potential inside the vesicles can facilitate the binding of polysialic acid chains to model lipid membranes. These observations suggest that these membrane potentials can also affect the polysialic acid-mediated interaction between cells.
