Rapid DNA detection and one-step RNA detection catalyzed by Bst DNA polymerase and narrow-thermal-cycling.

We reported a novel detection method named accelerated strand exchange amplification by employing Bst DNA polymerase and narrow-thermal-cycling for the first time, achieving direct detection of 120 copies of DNA within 15 min and 1.2 × 105 copies of RNA within 20 min and sparking the revolution of the use of routine isothermal polymerases for diverse applications.
