Compression at different rates. Monolayers of POPC spread to surface pressures <42 mN/m were first compressed at 26°C and 0.03 min−1 to 46 mN/m, and then to higher surface pressures at the indicated rates of area-compression expressed as d(ln A)/dt (see Methods). Area is normalized relative to the initial area at 46 mN/m (Ao). Curves give data from representative experiments. Symbols give mean ± SD at selected points averaged at common volumes for both area and surface pressures in three experiments.
