Publication number: 20230002754Abstract: Methods, kits and compositions, in some embodiments, may include a thermostable DNA guided Argonaute protein for example TtAgo, a thermostable single-stranded DNA binding protein (SSB) for example, extreme thermostable single-stranded DNA binding protein (ET SSB), and, optionally, a strand-displacing polymerase. A SSB may allow (a) Argonaute/guide DNA complexes to substantially enhance cleavage efficiency of single- and double-stranded DNA substrates; (b) the use of longer guide DNAs (e.g., guide DNAs that are at least 24 nucleotides in length) and/or (c) increases in the sequence specificity of Argonaute-mediated binding and cleavage reactions.Type: ApplicationFiled: September 7, 2022Publication date: January 5, 2023Applicant: New England Biolabs, Inc.Inventors: Nathan Tanner, Eric Hunt

Patent number: 11525166Abstract: Kits and methods are described that are directed to specific and sensitive methods of target nucleic acid detection and more specifically detecting target nucleic acids directly from biological samples. The kits and methods were developed to be easy to use involving a minimum number of steps and giving rapid and consistent results either at point of care or in high throughput situations. The kits and methods utilize in various combinations, reversible inhibitors of kit components, thermolabile enzymes, poloxamers, various salts, indicators and one or more Loop-Mediated Isothermal Amplification (LAMP) primer sets for detecting single and/or multiple targets and variants of the targets including SARS-CoV-2 targets and variants thereof in a single reaction. The kits and methods permit detection of the target nucleic with similar sensitivity regardless of the presence of undefined mutations that may enhance the virulence of cells or viruses containing the undefined mutations.Type: GrantFiled: March 21, 2022Date of Patent: December 13, 2022Assignee: New England Biolabs, Inc.Inventors: Nathan Tanner, Yinhua Zhang, Eric Hunt, Gregory Patton, Guoping Ren, Zhiru Li, Andrew Barry, Nicole Nichols, Catherine B.

Publication number: 20220380738Abstract: The present disclosure relates, according to some embodiments, to compositions, methods, systems, and kits for programmable endonucleolytic cleavage of DNA (e.g., ds DNA). For example, the in vitro activity of an Argonaute (e.g., a mesophilic Argonaute CbAgo from Clostridium butyricum) may be synchronized with DNA strand unwinding activity of a helicase (e.g., a nuclease deficient RecBexo-C DNA helicase from E. coli) for a rapid and efficient cleavage of double-stranded DNA targets. Enzymatic properties of CbAgo and different aspects of ds DNA cleavage were thoroughly explored by adapting high-throughput capillary electrophoreses technique for monitoring CbAgo cleavage activity in concurrence with RecBexo-C. The present disclosure shows that in the presence of RecBexo-C, CbAgo can be programmed with guides to cleave any site of interest localized at up to 10 kb distance from the end of linear ds DNA at 37° C. temperature.Type: ApplicationFiled: June 1, 2021Publication date: December 1, 2022Applicant: New England Biolabs, Inc.Inventors: Jurate Bitinaite, Rita Vaiskunaite, Vladimir Potapov, Nathan Tanner

Patent number: 11512342Abstract: Provided herein is a composition comprising an enzyme that releases pyrophosphate from a substrate and a dye of Formula 1. A method for detecting pyrophosphate is also provided. A kit comprising a polymerase that releases pyrophosphate by hydrolysis of nucleoside triphosphates during nucleic acid replication, a divalent manganese salt, and the dye are also provided. The present composition, method and kits provide a way to detect and/or quantify substrates or products of enzyme reacted substrates associated with the release pyrophosphate (e.g., nucleic acid amplification reactions and other reactions that hydrolyze ATP) via a distinct color change without substantially affecting the sensitivity and/or specificity of the reaction.Type: GrantFiled: May 4, 2022Date of Patent: November 29, 2022Assignee: New England Biolabs, Inc.Inventors: Nathan Tanner, Ivan R.
