Making the anti- motor phosphorus antibody connect which the cancer cell uniquely it is indwelling converts with the cation characteristic macromolecule, it transported nuclear acid inside the cancer cell uniquely, at the same time functioning inside the tumor cell it offered the nuclear acid carrier which can be able to point, established nuclear acid delivery method. In addition, nuclear acid or the reporter gene which possesses anti- cancer activity making use of the particular nuclear acid carrier by the fact that functioning it can point in the cancer cell, the anti- cancer medicine and the composition for the diagnostic medicine were offered.癌細胞特異的に内在化する抗モータリン抗体をカチオン性高分子と結合させて、核酸を癌細胞内に特異的に輸送し、かつ腫瘍細胞内で機能させることのできる核酸キャリアを提供し、核酸デリバリー法を確立した。また、当該核酸キャリアを用いて抗癌活性を有する核酸、またはレポーター遺伝子を癌細胞で機能させることで、抗癌剤及び診断剤用組成物を提供した。
