  • Title: Pulmonary surfactant protein SP-C causes packing rearrangements of dipalmitoylphosphatidylcholine in spread monolayers.
    Author: Pérez-Gil J, Nag K, Taneva S, Keough KM.
    Journal: Biophys J; 1992 Jul; 63(1):197-204. PubMed ID: 1420867.
    Abstract:
    The hydrophobic pulmonary surfactant protein SP-C has been isolated from porcine lung surfactant, and it has been incorporated into monolayers of dipalmitoylphosphatidylcholine (DPPC). The monolayers, which contained 1 mol% of a fluorescently-labeled phosphatidylcholine, were observed under various states of compression in an epifluorescence surface balance. SP-C altered the packing arrangements of DPPC in the monolayer, causing the production of many more, smaller condensed lipid domains in its presence than in its absence.
