A new method for membrane reconstitution: fusion of protein-containing vesicles with planar bilayer membranes below lipid phase transition temperature
Biophys Struct Mech.

Abstract
A new method of membrane reconstitution was developed by fusion of channel protein containing vesicles with planar bilayer membranes. The fusion process only occurred below and near the phase transition temperature of the lipid used. We obtained the following results: 1. Our system is solvent-free and vesicles do not come into contact with the air/water interface. This obviates a possible denaturation of hydrophobic proteins. 2. Channel forming proteins and protein complexes, respectively, are active in a frozen lipid matrix. 3. We detected an unknown channel in cilia fragments. 4. Purified acetylcholine receptors form fluctuating channels in a membrane consisting of a pure synthetic lecithin (two component system).
