The amyloid-beta (Abeta) peptide is a key aggregate species in Alzheimer's disease. Although important aspects of Abeta peptide aggregation are understood, the initial stage of aggregation from monomer to oligomer is still not clear. One potential mediator of this early
A new (to our knowledge) robust approach for the determination of lateral diffusion coefficients of weakly bound proteins is applied for the phosphatidylserine specific membrane interaction of bovine prothrombin. It is shown that z-scan fluorescence correlation spectroscopy in combination with

In the first article of this series we demonstrated the importance of specific intrapeptide interactions and peptide-lipid contacts for the membrane binding of penetratin (pAntp). Here in focus was detailed characterization of spatial hydrophobic/hydrophilic properties of the bilayer surface and

This paper describes a method to form giant liposomes in solutions of physiologic ionic strength, such as phosphate buffered saline (PBS) or 150 mM KCl. Formation of these cell-sized liposomes proceeded from hybrid films of partially dried agarose and lipids.

The lipid exchange/transfer between lipid membranes is important for many biological functions. To learn more about how the dynamics of such processes can be studied, we have investigated the interaction of positively and negatively charged lipid vesicles with supported lipid
