Target DNA induced switches of DNA polymerase activity

6 June, 2015 - 22:54

Chem. Commun., 2015, 51,9942-9945
DOI: 10.1039/C5CC02060C, CommunicationKi Soo Park, Chang Yeol Lee, Hyun Gyu Park
A novel concept that target DNA can induce switching of DNA polymerase activity is devised. The method relies on the finding that a DNA aptamer can undergo conformational change upon hybridization with a complementary target DNA, which leads to activation or inactivation of DNA polymerase. This strategy is utilized to identify the presence of target DNA with high levels of sensitivity and selectivity.
