The concentration of alamethicin in aqueous solutions was quantitated using measurements of the spot area on thin-layer chromatograms. These data were utilized to measure a partition coefficient of 17 for alamethicin in a phospholipid membrane-water system under equilibrium dialysis conditions.
Supplementary key words thin-layer chromatography cyclopeptide antibiotic phospholipid membranes equilibrium dialysis partition coefficient
