  • Title: Surfactant partition between bulk water and DPPC vesicle membrane: solid-gel vs. liquid-crystalline membrane.
    Author: Inoue T, Fukushima K, Shimozawa R.
    Journal: Chem Phys Lipids; 1990 Jan; 52(2):157-61. PubMed ID: 2311141.
    Abstract:
    The main phase transition temperature, Tm, of dipalmitoylphosphatidylcholine (DPPC) vesicle membrane was measured in the presence of the cationic surfactants tetradecyltrimethylammonium bromide and hexadecyltrimethylammonium bromide. Variation of the perturbing effect of these surfactants on Tm with the lipid concentration was analyzed according to the theory recently proposed by Kaminoh et al. (Y. Kaminoh, C. Tashiro, H. Kamaya and I. Ueda (1988) Biochim. Biophys. Acta 946, 215-220), and the partition coefficients of the surfactant into solid-gel and liquid-crystalline membranes were estimated.
