Abstract

The modern theory of lipid membrane structure incorporates the concept of lateral stress profile. The latter represents the forces that act on any solute inside the membrane. We used this concept to propose two lipid probes that introduce minimal distortions into the lipid bilayer packing: the surface pressure isotherms and volt-potentials of the pure and mixed (probe-containing) lipid monolayers are equal. The probes represent a FRET pair. They are applicable in lipid transfer and vesicle fusion experiments.

Keywords: FRET; Fluorescent lipid probes; Lateral stress profile; Phospholipid bilayer.
