Publication number: 20240218438Abstract: Disclosed herein is a method of causing enzymatic digestion of in vitro synthesised nucleic acid (especially DNA), the method comprising the steps of: (a) combining reagents, in the presence of a temporarily substantially inactive nuclease, to form in vitro synthesised nucleic acid; and (b) subsequently permitting or causing the substantially inactive nuclease to regain substantial nuclease activity after a period of time has elapsed sufficient to allow detection of the in vitro synthesised nucleic acid, such that the in vitro synthesised nucleic acid is digested by the nuclease.Type: ApplicationFiled: May 27, 2022Publication date: July 4, 2024Inventors: Victor Perez, Alexis Quintilliani, Bryan Kraynack, Daiwei Shen, Jarrod Provins

Publication number: 20240026433Abstract: Disclosed is a method of performing a non-isothermal nucleic acid amplification reaction, the method comprising the steps of: (a) mixing a target sequence with one or more complementary single stranded primers in conditions which permit a hybridisation event in which the primers hybridise to the target, which hybridisation event, directly or indirectly, leads to the formation of a duplex structure comprising two nicking sites disposed at or near opposite ends of the duplex; and performing an amplification process by; (b) using a nicking enzyme to cause a nick at each of said nicking sites in the strands of the duplex; (c) using a polymerase to extend the nicked strands to as to form newly synthesised nucleic acid, which extension with the polymerase recreates nicking sites; (d) repeating steps (b) and (c) as desired so as to cause the production of multiple copies of the newly synthesised nucleic acid; characterised in that the temperature at which the method is performed is non-isothermal, and subject to shuType: ApplicationFiled: April 20, 2023Publication date: January 25, 2024Inventors: Daiwei Shen, Bryan Kraynack, Victor Perez, Jarrod Provins
