FIGURE 3 Formation of planar supported bilayers containing asymmetric lo phase domains. Bilayers were made by the LB/VF technique at room temperature. The LB monolayer was composed of bPC/bSM/cholesterol (2:2:1) + 3% DPS (A and B), or without DPS (C). The vesicles contained either POPC + 20% cholesterol (A), bPC, bPE, bPS, and cholesterol (B), or POPC only (C). Formation of the bilayer was monitored by TIRFM with 0.5% Rh-DPPE added to the vesicles only (panels on the left). The stability of the LB monolayer during incubation with vesicles was examined by imaging with 0.5% Rh-DPPE added to the LB monolayer only (micrographs on the right). The white bar represents 20 µm.
