The authors conducted a synthetic peptide SP-C analog-based surfactant study. We selected the peptide sequence CP VHLKRLLLLLLLLLLLLLLLL [SP-CL16(6-28)] for the SP-C analog using the methods of Otsubo, et al.

and Chida, et al.*

The peptide analog sequence was designed under Chida, et al.’s study including surface properties and electron micro- scopic findings of surfactant containing [SP-CL16(6-28)].*

Modified Wilhelmy balance equipment (Acoma, Tokyo, Japan, at Department of Pediatrics, Iwate Medical University, Iwate, Japan) was used to measure surface spreading rate and surface adsorption rate and to obtain an ST-area diagram.

We thank Professor Shoichi Chida and his co-workers, Department of Pediatrics, Iwate Medical University, Japan, for their support to use the modified Wilhelmy balance test. This work was supported by the Kyung Hee University research fund (20110897).
