Effect of surfactant protein SP-B, at the indicated protein/lipid weight percent, on the morphology and size of large micrometer-sized condensed microdomains in DPPC/DPPG (7:3, w/w) monolayers. Micrographs show contact mode SFM images from monolayers transferred to mica once compressed to 11 mN/m, and cover 50 μm width. (a) π-A isotherms of DPPC/DPPG monolayers in the absence (continuous line) and in the presence (dashed lines) of 2, 5, 10, and 20% SP-B (w/w), compressed up to the transfer pressure (11 mN/m). (b) Effect of SP-B on the percent of total area in the films occupied by LC microdomains.
