  • Patent number: 8563711
    Abstract: The present invention relates to a nucleic acid aptamer which can specifically recognize and bind to pancreatic cancer cells or tissues. The nucleic acid aptamer can bind specifically only to pancreatic cancer cells or tissues without binding to normal pancreatic cancer tissue, and thus can be effectively used as a composition for diagnosing and treating pancreatic cancer. In addition, the nucleic acid aptamer can detect not only the terminal pancreatic cancer cell line Capan-1, but also the early pancreatic cancer cell line Panc-1, and thus can be used for early diagnosis of pancreatic cancer, thereby contributing to increasing the survival rate of pancreatic cancer patients.
