中文摘要
目的制备腺病毒及紫杉醇阴离子脂质体(AL-Ad5-PTX)共传递复合物,考察该复合物物理性质及体外细胞转染效率。方法先后用薄膜超声法和钙离子融合法制得AL-Ad5-PTX;测定AL-Ad5-PTX中紫杉醇的含量;测定粒径及电位;用透射电镜观察其形态;以表达荧光素酶的重组腺病毒作为病毒载体,比较AL-Ad5-PTX和裸腺病毒(naked Ad5)在富含柯萨奇腺病毒受体(CAR)或缺乏CAR受体细胞中的转染效率。结果 AL-Ad5-PTX中紫杉醇包封率为82.70%±2.47%,粒径为241.6±2.6 nm,粒径分布为0.196±0.006,电位为-50.4±5.4 mV。AL-Ad5-PTX在两种细胞中的转染效率高于naked Ad5(P
