The nucleic acid carrier for introducing the nucleic acid into the cancer cells

The anti-mortalin antibody cancer cells specifically internalized by bonding with a cationic polymer, a nucleic acid specifically transported into the cancer cells, and provides a nucleic acid carrier that can function in tumor cells, nucleic acid It was established delivery method. Nucleic acids have anti-cancer activity using the nucleic acid carrier or reporter gene, by function in cancer cells, to provide an anticancer agent and diagnostic agent composition.
