Dynamic PBS results as γ versus relative surface area (surface area/maximum surface area) at 20 cycles/min for 5 min. (A) The bulk surfactant concentration was 1 mg/mL lipids (DPPC/POPG/PA, 68:22:9 (wt)) at 37°C. First compression surface pressure (Π)-area (A) LWSB isotherms for the formulations were collected on a buffered subphase at 37°C. (B) LWSB molecular areas include all surfactant species, lipid plus SP-C/peptoid.
