摘要: A method for determining the sequence of a target nucleic acid, including steps of contacting a target nucleic acid with a polymerase to sequentially remove nucleotide triphosphates from the target nucleic acid, wherein the nucleotide triphosphates that are removed have a variety of different base moieties; and distinguishing the different base moieties for the nucleotide triphosphates that are removed. Also provided is a apparatus including a nanopore positioned in a fluid impermeable barrier to form a passage through which a nucleotide triphosphate can pass from a first fluid reservoir to a second fluid reservoir, and a reaction mix in the first fluid reservoir that includes a polymerase, target nucleic acid having two strands, and pyrophosphorolytic concentration of pyrophosphate.

摘要: Disclosed is a system for determining the nucleotide sequence of polynucleotides. The system can comprise a light source, such as a laser or a LED, configured to generate light at a predetermined wavelength. A detector of the system can detect fluorescent emissions at a first wavelength and a second wavelength. A processor of the system identify the nucleotide as a first type if no fluorescent emission is detected by the at least one detector; identify the nucleotide as a second type if a fluorescent emission at the first wavelength of light is detected by the at least one detector; identify the nucleotide as a third type if a fluorescent emission at the second wavelength of light is detected by the at least one detector; and identify the nucleotide as a fourth type if fluorescent emissions at the first wavelength and the second wavelength of light are detected by the at least one detector.

摘要: In an example, a flow cell includes a substrate, a selectively removable porous molecular network on the substrate and defining exposed substrate regions, and sequencing surface chemistry on at least some of the exposed regions. The sequencing surface chemistry is selected from the group consisting of i) an activated pad, a polymer layer attached to the activated pad, and a primer attached to the polymer layer; or ii) a nanostructure and an enzyme attached to the nanostructure.

摘要: Embodiments of the present disclosure relate to methods of preparation of templates for polynucleotide sequencing. In particular, the disclosure relates to linearization of clustered polynucleotides in preparation for sequencing by cleavage of one or more first strands of double-stranded polynucleotides immobilized on a solid support by a transition metal complex, for example, a palladium complex or a nickel complex. Further disclosure relate to linearization of clustered polynucleotides by cleaving one or more second strands of double double-stranded polynucleotides immobilized on a solid support comprising azobenzene linker by Na2S2O4. Nucleotides and oligonucleotides comprising a 3′ phosphate moiety blocking group, and methods of removing the same using a fluoride reagent are also disclosed.

摘要: An apparatus for directing fluid into and out of a fluidic device includes two or more fluid prime channels connected to a fluid inlet of the fluidic device, a flow control valve for each fluid prime channel to control flow between the fluid prime channel and the fluid inlet, one or more outlet channels connected to a fluid outlet of the fluidic device, and a flow control valve for each outlet channel to control flow between the fluid outlet and the associated outlet channel. An apparatus for delivering fluids to a fluid inlet includes a plate that is rotatable about an axis of rotation and a plurality of fluid compartments disposed on the plate, each compartment having a fluid exit port disposed at a common radial distance from the axis of rotation and positioned to align with the fluid inlet as the plate rotates about the axis of rotation.

摘要: Provided herein is a method for sequencing a polynucleotide molecules. The method includes the steps of providing a plurality of polynucleotide molecules attached to a surface, wherein a first portion of each polynucleotide molecule is attached to a first location of the surface and a second portion of each polynucleotide molecule is attached to a second location of the surface, the relative proximity of the first and second locations being correlated with the probability that the first and second portions are paired, separating the first and second portions of the polynucleotide molecules on the surface, determining the sequences of the first and second portions of the polynucleotide molecules and comparing the relative proximities and the sequences to determine which first and second portions are paired and to determine the sequence of the target polynucleotide molecules.
