Novel Strategy

A G-quadruplex probe incorporating 2-AP is utilized to develop a novel strategy to accurately determine UDG activity. The excision reaction promoted by UDG is designed to trigger the formation of G-quadruplex structure with significant fluorescence enhancement of 2-AP within the probe. By employing this strategy, UDG activity can be reliably determined with high sensitivity and specificity.
