  • Patent number: 11827934
    Abstract: Compositions, methods and systems are provided for isolating nucleic acids. A polymerase-nucleic acid complex can be formed by mixing a polymerase enzyme comprising strand displacement activity and a mixture of double stranded nucleic acids. Nucleic acid synthesis can then be initiated by the polymerase enzyme to produce a nascent strand complementary to the first strand, thereby displacing a portion of the second strand. After halting or reducing the rate of nucleic acid synthesis, a hybridizing a hook oligonucleotide can be used hybridize to the nucleic acid through a capture region on the hook oligonucleotide that is complementary to the displaced portion of the second strand. The nucleic acid can then be isolated from the mixture of nucleic acids using the hook oligonucleotide.

  • Patent number: 11773437
    Abstract: A circuit comprising a substrate with sectors on the substrate is provided, each sector comprising clock and data lines, a controller in electrical communication with the clock and data lines, a counter bias line, an amplifier input line and nano-electronic measurement devices on the substrate. A source of each device is coupled to the counter bias line and a drain of each device is coupled to the amplifier input line to obtain an electrical signal on the drain, the identity of which is determined by electrical interaction between the device and a charge label. Each device drain is gated by a corresponding switch between an on state, in which the drain is connected to the amplifier input line, and an off state, in which the drain is isolated from the amplifier input line. The controller controls switch states responsive to clock signal line pulses and data input line data.

  • Patent number: 11584959
    Abstract: Methods are provided for reducing the complexity of a population of nucleic acids prior to performing an analysis of the nucleic acids, e.g., sequence analysis. The methods result in a subset of the initial population enriched for a target region, which is typically located within one or more target fragments. The methods are particularly useful for analyzing populations having a high degree of complexity, e.g., chromosomal-derived DNA, whole genomic DNA, or mRNA populations.

  • Publication number: 20220064725
    Abstract: Real time electronic sequencing devices, chips, and systems are described. Arrays of nanoFET devices are used to provide sequence information about a template nucleic acid in a polymerase-template complex bound to the nanoFET. The nanoFET devices typically have a source, a drain and a gate comprising a nanowire. A single polymerase enzyme complex comprising a polymerase enzyme complexed with the template nucleic acid is bound to the gate. The polymerase is bound to the gate non-covalently through a polymeric binding agent that has two strands, each strand interacting with the nanowire such that the polymerase is in a central location between the strands with the polymeric binding agent extending away from the polymerase complex along the nanowire in both directions.

  • Patent number: 10934585
    Abstract: Compositions, methods and systems are provided for the loading of extended polymerase-nucleic acid complexes onto substrates. Primed polymerase-template complex comprising a polymerase enzyme and a circular nucleic acid template comprising a double stranded region connected at each end by a single-stranded hairpin region are provides in which the circular nucleic acid template comprises at least one reversible pause point. Nucleic acid synthesis is carried out such that a nascent strand is synthesized up to the reversible stop point producing an extended polymerase-template complex. The extended polymerase-template complex is then attached to a substrate. Such attached complexes can be used for single molecule sequencing in which the nucleic acid synthesis is re-initiated such that nucleic acid synthesis continues past the reversible stop point.
