Provided herein is a method for denaturation bubble-mediated target nucleic acid amplification and related kits and uses thereof. The method facilitates the generation of denaturation bubbles in a duplex target nucleic acid molecule through the application of swift temperature changes during a thermal cycle, thereby accelerating the strand exchange amplification (SEA) reaction. The kits comprise specially designed primers and polymerase configured for performing the method. The methods and kits disclosed herein can be used under various scenarios, such as diagnosis of infectious or genetic diseases, sample quality control, and single nucleotide polymorphism (SNP) profiling.

A method of analysing for a single stranded nucleic acid present, or potentially present, in a sample comprises a step in which the target nucleic acid (if present in the sample) displaces—and hybridises to—a reporter strand originally present in an interrogating duplex structure comprised of the reporter strand and a displaceable shorter strand. The reporter strand is tagged at or adjacent one end thereof with a reporter moiety capable of providing a detectable signal. The reporter/target duplex structure is such that the reporter strand may be selectively enzymatically digested (e.g. by means of λ-exonuclease) from its end opposite the reporter moiety to release that moiety for direct or indirect detection and regenerate single stranded target, which may then cycle through a plurality of the displacement and digestion steps to result in amplification of signal.
