COMPOSITIONS AND METHODS FOR PREPARING NUCLEIC ACID NANOSTRUCTURES USING COMPACTION OLIGONUCLEOTIDES
Publication number: 20240084380Abstract: The present disclosure provides compositions and related methods, e.g., for preparing immobilized nucleic acid nanostructures using compaction oligonucleotides. In some embodiments, rolling circle amplification reaction can be conducted with compaction oligonucleotides on-support or in-solution to generate concatemer molecules having multiple copies of a polynucleotide unit arranged in tandem. Each polynucleotide unit comprises a sequence-of-interest and at least one universal adaptor sequence that binds one end of a compaction oligonucleotide. The 5? and 3? regions of the compaction oligonucleotide can hybridize to the concatemer to pull together distal portions of the concatemer causing compaction of the concatemer to form a nanostructure. Nanostructures having tighter size and shape compared to concatemers generated in the absence of the compaction oligonucleotides.Type: ApplicationFiled: August 15, 2023Publication date: March 14, 2024Inventors: Sinan ARSLAN, Michael KIM, Ramreddy TIPANNA, Chunhong ZHOU, William LIGHT, Hua YU, Junhua ZHAO, Tsung-Li LIU -
Patent number: 11891651Abstract: The present disclosure provides compositions and methods that employ the compositions for conducting pairwise sequencing and for generating concatemer template molecules for pairwise sequencing. The concatemers can be generated using a rolling circle amplification reaction which is conducted either on-support, or conducted in-solution and then distributed onto a support. The rolling circle amplification reaction generates concatemers containing tandem copies of a sequence of interest and at least one universal adaptor sequence. An increase in the number of tandem copies in a given concatemer increases the number of sites along the concatemer for hybridizing to multiple sequencing primers which serve as multiple initiation sites for polymerase-catalyzed sequencing reactions. When the sequencing reaction employs detectably labeled nucleotides and/or detectably labeled multivalent molecules (e.g.Type: GrantFiled: November 8, 2021Date of Patent: February 6, 2024Assignee: Element Biosciences, Inc.Inventors: Sinan Arslan, Junhua Zhao, Molly He, Samantha Snow, William Light, Matthew Kellinger, Michael Previte, Michael Kim, Hua Yu, Yu-Hsien Hwang-Fu, Marco Tjioe, Andrew Boddicker

Publication number: 20230323450Abstract: Multivalent binding compositions including a particle-nucleotide conjugate having a plurality of copies of a nucleotide attached to the particle are described. The multivalent binding compositions allow one to localize detectable signals to active regions of biochemical interaction, e.g., sites of protein-protein interaction, protein-nucleic acid interaction, nucleic acid hybridization, or enzymatic reaction, and can be used to identify sites of base incorporation in elongating nucleic acid chains during polymerase reactions and to provide improved base discrimination for sequencing and array based applications.Type: ApplicationFiled: March 9, 2023Publication date: October 12, 2023Inventors: Sinan Arslan, Molly Min HE, Matthew KELLINGER, Jake LEVIEUX, Michael PREVITE, Junhua ZHAO, Su ZHANG, Tyler LOPEZ

Patent number: 11781185Abstract: Provided herein are fluorescently-labeled nucleotide conjugates for nucleic acid analysis. Also provided are reagents used for forming binding complexes between a fluorescently-labeled nucleotide conjugate and a target nucleic acid sequence in the presence of one or more reagents disclosed herein. Binding complexes can be detected in the presence of the one or more reagents. For example, the one or more reagents may contain a photobleaching reducing agent configured to reduce photobleaching resulting from use of the fluorescently-labeled nucleotide conjugate to form the binding complex in a nucleic acid analysis. Such nucleic acid analysis may be used to identify sites of nucleobase binding or incorporation between the target nucleic acid sequence and one or more nucleotide moieties of the fluorescently-labeled nucleotide conjugate in a nucleic acid sequence reaction.Type: GrantFiled: September 19, 2022Date of Patent: October 10, 2023Assignee: ELEMENT BIOSCIENCES, INC.Inventors: Sinan Arslan, Molly He, Michael Previte, Ramreddy Tippana, Hua Yu, William Light, Junhua Zhao
