Patent number: 11807896Abstract: Disclosed herein are compositions, systems, kits and methods related to preserving physical linkage information of isolated DNA subject to DNA damage, and identifying a nucleic acid preservative. Physical linkage information and DNA integrity may be preserved by methods relating to reassembly of chromatin onto isolated DNA molecules so as to protect the nucleic acids, preserve physical linkage information, or size select molecules of interest. Nucleic acid compositions produced by methods disclosed herein are preserved so as to be analyzed, for example, by high throughput sequencing methods.Type: GrantFiled: March 25, 2016Date of Patent: November 7, 2023Assignee: Dovetail Genomics, LLCInventors: Brandon J. Rice, David Haussler

Patent number: 11600361Abstract: Disclosed herein are compositions, systems and methods related to sequence assembly, such as nucleic acid sequence assembly of single reads and contigs into larger contigs and scaffolds through the use of read pair sequence information, such as read pair information indicative of nucleic acid sequence phase or physical linkage.Type: GrantFiled: February 13, 2019Date of Patent: March 7, 2023Assignee: Dovetail Genomics, LLCInventors: Nicholas H. Putnam, Jonathan C. Stites, Brandon J. Rice

Patent number: 10975417Abstract: Disclosed herein are methods, compositions and systems that facilitate accurate phasing of sequence data such as genomic sequence data through the segmentation and rearrangement of nucleic acid molecules in such a way as to preserve individual molecules phase or physical linkage information. This is variously accomplished by binding molecules independent of their phosphodiester backbones, cleaving the molecules, ligating, and sequencing the molecules through long-read sequencing technology to recover segment sequence information spanning at least more than one segment.Type: GrantFiled: February 23, 2017Date of Patent: April 13, 2021Assignee: DOVETAIL GENOMICS, LLCInventors: Richard E. Green, Jr., Daniel S. Rokhsar, Paul Hartley, Marco Blanchette

Patent number: 10947579Abstract: The disclosure provides methods to isolate genome or chromosome level structural information from preserved samples. In some cases, samples preserved under conditions where long-range nucleic acid information is believed to be irreparably lost, such as FFPE samples, are treated to recover nucleic acid-protein complexes stabilized as part of the sample preservation process. The complexes are processed so as to recover information regarding which nucleic acids are bound to a common complex, and the information is used to recover genomic structural information.Type: GrantFiled: August 2, 2018Date of Patent: March 16, 2021Assignee: DOVETAIL GENOMICS, LLCInventors: Christopher John Troll, Martin P. Powers, Nicholas H. Putnam, Marco Blanchette, Paul Hartley

Patent number: 10526641Abstract: Various approaches for generating long-distance contiguity information to facilitate contig assembly and phase determination are disclosed. Nucleic acids are assembled into complexes using binding moieties such that, when the nucleic acid backbones are cleaved, the ensuing fragments remain bound. Exposed ends are tagged and ligated either to one another or to tagging moieties such as oligo labels. Ligated junctions are sequenced, and the sequence information is used to assemble contigs into common scaffolds or to assign phase information. Various approaches to tagging the exposed ends are presented.Type: GrantFiled: July 31, 2015Date of Patent: January 7, 2020Assignee: DOVETAIL GENOMICS, LLCInventors: Andrew Fields, Paul Hartley, Nicholas Putnam, Brandon Rice, Jonathan Stites

Patent number: 10457934Abstract: The disclosure provides methods to assemble genomes of eukaryotic or prokaryotic organisms. The disclosure provides methods for haplotype phasing and meta-genomics assemblies. The disclosure provides a streamlined method for accomplishing these tasks, such that intermediates need not be labeled by an affinity label to facilitate binding to a solid surface. The disclosure also provides methods and compositions for the de novo generation of scaffold information, linkage information, and genome information for unknown organisms in heterogeneous metagenomic samples or samples obtained from multiple individuals. Practice of the methods can allow de novo sequencing of entire genomes of uncultured or unidentified organisms in heterogeneous samples, or the determination of linkage information for nucleic acid molecules in samples comprising nucleic acids obtained from multiple individuals.Type: GrantFiled: July 13, 2017Date of Patent: October 29, 2019Assignee: Dovetail Genomics, LLCInventors: Richard E. Green, Paul Hartley, Christopher Troll, Ei Ei Min
