| Abstract: | Branched bimolecular lipid membranes separating three and four aqueous phases have been formed. The procedure is based on the technique of Montal and Mueller generalized to three and four lipid surface films spanning an appropriate aperture. The technique to produce Teflon structures for the mechanical support of branched bilayers is presented. The existence of the branched bilayer was established by measuring the specific capacity, specific resistance, and the gramicidin-induced single channel conductance of each branch. These structures should facilitate the study of transport properties of ionophores and other molecules and may also serve as model systems for the study of cell fusion. |
