Surface-pressure-area isotherm of DPPC/POPG/PA (68:22:8 wt %) monolayers with varying weight fractions of SP-Cff. Adding SP-Cff shifts the isotherms to larger area/molecule, showing that the protein has incorporated into the interface. The pronounced plateau at ∼40 mN/m shows that the monolayer loses material or is strongly condensed. This is consistent with the multilayer formation shown in Fig. 4.
