Aptamer-driven PS-THSP strategy for rapid and highly sensitive detection of ATP
We developed an aptamer-mediated system that enables rapid, sensitive, and discriminative quantification of ATP by utilizing phosphorothioate-terminal hairpin formation and self-priming extension (PS-THSP). In this method, the aptamer hairpin probe (AptHP), a key component, binds to ATP through its…
