Figure 2.

Insertion of KR₉C into 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC)/DOPG monolayers at 30 mN/m and 23 °C followed by fluorescence microscopy. Ten micrometers of the peptide were injected into the subphase at t = 0. (a) Representative images at the indicated times after peptide addition. (b) Percent of the area occupied by the darker regions, which corresponds to liquid-condensed phase state. (c) Number of domains in a 100 μm² region.
