Erratum to “Development of a Synthetic Surfactant Using a Surfactant Protein-C Peptide Analog: In Vitro Studies of Surface Physical Properties” by Bae CW, et al. (Yonsei Med J 2016;57(1):203–208.)

Dear Editor

We would like to correct our previously published article as below descriptions. Changes are marked by underline. The authors regret these errors.

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.¹⁵ and Chida, et al.^* The peptide analog sequence was designed under Chida, et al.'s study including surface properties and electron microscopic 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.
