  • Patent number: 11680253
    Abstract: Methods for labeling and imaging the accessible genome using a transposase are disclosed. In some embodiments, a bifunctional transposase complex or transposome is used to insert adaptors comprising chemical tags selectively at accessible sites in the genome where active regulatory DNA is located. Various chemical tags can be used for labeling DNA at insertion sites, including, for example, fluorescent dyes for fluorescence imaging, metal particles for electron microscopy or magnetic manipulation of DNA, isotopic labels, or biotin or other ligands, haptens, substrates, or inhibitors that are recognized by streptavidin, antibodies, enzymes, or receptors. Labeling DNA in this manner can be used to provide spatial information regarding the positioning of regulatory DNA in the genome and makes possible the imaging and sorting of cells based on the status of their regulatory DNA.

  • Patent number: 11242562
    Abstract: Next Generation DNA sequencing promises to revolutionize clinical medicine and basic research. However, while this technology has the capacity to generate hundreds of billions of nucleotides of DNA sequence in a single experiment, the error rate of approximately 1% results in hundreds of millions of sequencing mistakes. These scattered errors can be tolerated in some applications but become extremely problematic when “deep sequencing” genetically heterogeneous mixtures, such as tumors or mixed microbial populations. To overcome limitations in sequencing accuracy, a method Duplex Consensus Sequencing (DCS) is provided. This approach greatly reduces errors by independently tagging and sequencing each of the two strands of a DNA duplex. As the two strands are complementary, true mutations are found at the same position in both strands. In contrast, PCR or sequencing errors will result in errors in only one strand.

    Abstract: The present invention is directed to a polymerase activity assay that produces a strong optical signal when a primer-template complex is extended to full-length product. The assay uses Cy3 as the molecular beacon and Iowa Black® RQ as the quencher. The signal-to-noise-ratio (STNR) of this donor-quencher pairing is ˜200-fold over background, which is considerably better than other donor-quencher pairs (STNRs ˜10-20-fold). The STNR allows for solution-based monitoring of polymerase activity. Because the sensor functions via Watson-Crick base pairing, the polymerase activity assay may also be used to evolve polymerases to accept xeno nucleic acids as substrates.

  • Patent number: 11142785
    Abstract: The present technology provides for an apparatus for detecting polynucleotides in samples, particularly from biological samples. The technology more particularly relates to microfluidic systems that carry out PCR on nucleotides of interest within microfluidic channels, and detect those nucleotides. The apparatus includes a microfluidic cartridge that is configured to accept a plurality of samples, and which can carry out PCR on each sample individually, or a group of, or all of the plurality of samples simultaneously.

  • Patent number: 11079388
    Abstract: An imaging agent comprises (a) at least one target recognition moiety; (b) at least one observable moiety non-transiently bound to the target recognition moiety, and (c) at least one docking moiety bound to the target recognition moiety, wherein the docking moiety is capable of transiently binding at least one observable moiety. In some embodiments, the at least one target recognition moiety is an antibody or antigen binding fragment thereof.

  • Patent number: 11071963
    Abstract: Methods and apparatus relate to the synthesis of high fidelity polynucleotides and to the reduction of sequence errors generated during synthesis of nucleic acids on a solid support. Specifically, design of support-bound template oligonucleotides is disclosed. Assembly methods include cycles of annealing, stringent wash and extension of polynucleotides comprising a sequence region complementary to immobilized template oligonucleotides. The error free synthetic nucleic acids generated therefrom can be used for a variety of applications, including synthesis of biofuels and value-added pharmaceutical products.

  • Patent number: 11060131
    Abstract: A method and kit for the capture and purification of specific nucleic acids from a sample with affinity capture probes on a solid support and for the replication of said nucleic acids with a strand displacing polymerase, whereby a second primer complementary to a sequence in each of the target nucleic acids distinct from that bound by capture probes is also bound to the nucleic acid targets, and extension of one of the primers on each target effects the separation of the copied nucleic acid strands from the solid support. Incorporation of universal nucleic acid sequences during their replication enables the simultaneous and highly specific amplification of multiple nucleic acid target sequences with minimal production of artifacts.
