Patent number: 11535892Abstract: 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: July 15, 2021Date of Patent: December 27, 2022Assignee: 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: 20220333178Abstract: A method for seeding and amplifying target nucleic acids derived from a sample in a cluster at a site on a surface of a substrate includes retaining at least a portion of the target nucleic acids in an inactive form that cannot seed to provide a relatively low concentration of active form target nucleic acids available for seeding. As the active form target nucleic acids seed on the surface of the substrate, they may be amplified. Because the concentration of active form target nucleic acids is low, the likelihood is low that a second active form target nucleic acid will seed at the same site within the same cluster before the first active form target nucleic acid is sufficiently amplified to dominate. Accordingly, the likelihood that the cluster will pass filters is increased relative to traditional seeding and amplification methods employing a higher concentration of active form target nucleic acids.Type: ApplicationFiled: March 21, 2022Publication date: October 20, 2022Inventors: Gary Mark Skinner, Geraint Evans, Niall Gormley, Jonathan Boutell, Matthew W.

Patent number: 11447756Abstract: Provided herein are compositions and systems for use in polymerase-dependent, nucleotide transient-binding methods. The methods are useful for deducing the sequence of a template nucleic acid molecule and single nucleotide polymorphism (SNP) analyses. The methods rely on the fact that the polymerase transient-binding time for a complementary nucleotide is longer compared to that of a non-complementary nucleotide. The labeled nucleotides transiently-binds the polymerase in a template-dependent manner, but does not incorporate. The methods are conducted under any reaction condition that permits transient binding of a complementary or non-complementary nucleotide to a polymerase, and inhibits nucleotide incorporation.Type: GrantFiled: March 20, 2020Date of Patent: September 20, 2022Assignee: LIFE TECHNOLOGIES CORPORATIONInventors: Peter Vander Horn, Cheng-Yao Chen, Guobin Luo, Michael Previte, Jamshid Temirov, Theo Nikiforov, Zhaohui Zhou, Hongye Sun, Yufang Wang, Stefanie Yukiko Nishimura, Hongyi Wang, Marian Peris, Barnett Rosenblum, Michael Phelan
