The present invention relates to compositions and methods of immobilizing a viral vector to an implantable medical device, for example a vascular stent. Specifically, a composition for delivery of a therapeutic agent is provided which includes: a gene transfer vector, a surface and a modified protein, wherein the gene transfer vector is bound to the modified protein and the modified protein is covalently bound to the surface and wherein the composition is adapted to deliver the gene transfer vector to a mammalian cell. The viral vector is preferably an adenoviral vector and the modified protein is preferably CAR D1.
本发明涉及将病毒载体固定到可植入医疗器械上的组合物和方法,例如血管支架。具体而言,提供了一种适用于输送治疗剂的组合物,包括:
基因转移载体、表面和修饰蛋白质,其中
基因转移载体与修饰蛋白质结合,修饰蛋白质与表面共价结合,组合物适用于将
基因转移载体输送到哺乳动物细胞。病毒载体优选为腺病毒载体,修饰蛋白质优选为CAR D1。
