実験手順

1 ml of a 10 mg/ml solution of doxorubicin HCl dissolved in saline-desferal was added to I ml of the liposome dispersion after the liposomes were gel filtrated on a Sephadex G-50 column. The mixture was incubated at room temperature for approximately 24 hours. The incubation was shorter for certain types of kinetic experiments. At the end of incubation period, the mixture was passed through a Dowex 50 WX-4 column to adsorb the free drug. The resin is able to adsorb as much as 1 mg of free doxorubicin in a 15 min time while the sequestered liposome incorporated remains with the liposomes. A column containing 1-2 g dry weight of the resin was sufficient to adsorb all unincorporated drug. To determine the ratio of incorporated drug to liposomal lipid., the phospholipid and doxorubicin concentration were determined as described previously.
