  • Publication number: 20230119862
    Abstract: The present invention relates to a self-priming hairpin-mediated isothermal amplification (SP-HAMP) and, more specifically, to a hairpin probe having a self-priming structure, which is for detecting a target nucleic acid and can be used in the nucleic acid isothermal amplification, and to a method for detecting a target nucleic acid by using same. The SP-HAMP technique according to the present invention is convenient due to no need of a separate primer with a complicated design required in existing LAMP technology, has improved efficiency of detection compared with existing LAMP reactions, and can detect DNA as well as RNA as a target nucleic acid, and therefore the technique according to the present invention can be applied in a wider variety of fields.

  • Publication number: 20230002804
    Abstract: The present invention relates to a detection method for detecting a target RNA contained in a sample with high sensitivity by using nicking/extension chain reaction system-based isothermal nucleic acid amplification (NESBA) that uses activity of a cleavage enzyme and a DNA polymerase. The NESBA of the present invention is a new concept isothermal target RNA detection method that realizes higher amplification efficiency than the existing NASBA technology and is deemed to be utilizable as a new concept diagnosis technology that can replace conventional target RNA detection technologies.
