S. Banerjee et al., EVALUATION OF DRUG LIPID ASSOCIATION CONSTANTS FROM MICROELECTROPHORETIC MOBILITY MEASUREMENTS, Langmuir, 11(4), 1995, pp. 1134-1137
Electrophoretic mobilities of negatively charged lipid vesicles were m
easured after incubation with cationic drugs (adriamycin, celiptium, e
thidium bromide, tetracaine) at different drug concentrations. We show
here that comparison of the measured electrophoretic mobility with ad
sorption isotherms allows calculation of the drug-binding constants ov
er a large range of drug concentrations, whatever the structure of the
drug, its topology into the lipid bilayer, or its aggregation state.
