実験手順
1 ml of a 10 mg/ml solution of doxorubicin HCl dissolved in saline-desferal was added to 1 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. At the end of incubation period, the mixture was passed through a Dowex 50 WX-4 (Serva) column to adsorb the free unincorporated drug. As small amount as 60 mg of the resin is able to adsorb as much as 1 mg of free doxorubicin in a time shorter than less than 15 minutes while liposome incorporated doxorubicin does not adsorb to the dowex resin at all and 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 in Example 1.
