A method for synthesizing a nucleic acid includes synthesizing one or more nucleic acid fragments on a substrate. The synthesized one or more nucleic acid fragments may be amplified on the substrate. The method also includes sequencing the synthesized or amplified one or more nucleic acid fragments on the substrate. The sequencing may provide feedback to designs of the one or more nucleic acid fragments. The method further includes harvesting the synthesized or amplified one or more nucleic acid fragments based on sequencing. The synthesized or amplified one or more nucleic acid fragments may be assembled to generate a target nucleic acid.

Nucleic acid synthesis techniques

This disclosure provides a method of determining a sequence of nucleotides for a nucleic acid template. The method can include the steps of contacting the nucleic acid template with a conformationally labeled polymerase and at least four different nucleotide species under conditions wherein the conformationally labeled polymerase catalyzes sequential addition of the nucleotide species to form a nucleic acid complement of the nucleic acid template, wherein the sequential addition of each different nucleotide species produces a conformational signal change from the conformationally labeled polymerase and wherein the rate or time duration for the conformational signal change is distinguishable for each different nucleotide species; detecting a series of changes in the signal from the conformationally labeled polymerase under the conditions; and determining the rates or time durations for the changes in the signal, thereby determining the sequence of nucleotides for the nucleic acid template.

Conformational probes and methods for sequencing nucleic acids

Disclosed herein are modified polymerase compositions exhibiting altered polymerase activity, which can be useful in a variety of biological applications. Also disclosed herein are methods of making and using such compositions. In some embodiments, the compositions exhibit altered properties that can enhance their utility in a variety of biological applications. Such altered properties, can include, for example, altered nucleotide binding affinities, altered nucleotide incorporation kinetics, altered photostability and/or altered nanoparticle tolerance, as well as a range of other properties as disclosed herein.

Polymerase compositions and methods

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.

Nucleotide transient binding for sequencing methods

Presented herein are polymerase enzymes for improved incorporation of nucleotide analogues, in particular nucleotides which are modified at the 3' sugar hydroxyl, as well as methods and kits using the same.

Modified polymerases for improved incorporation of nucleotide analogues

A method of distinguishing nucleotide sequences for different nucleic acid molecules including the steps of (a) mixing a plurality of different nucleic acid molecules with polymerase molecules and nucleotide molecules, wherein the different nucleic acid molecules are attached to a surface in the form of an array of nucleic acid features; (b) determining a transient state of the polymerase molecules at the nucleic acid features; and (c) identifying a subset of nucleic acid features that correctly incorporate the nucleotide molecules based on the transient state of the polymerase molecules at the nucleic acid features, thereby distinguishing the nucleotide sequences for the different nucleic acid molecules.

Apparatus and methods for kinetic analysis and determination of nucleic acid sequences

Provided herein are systems and methods for nucleotide incorporation reactions. The systems comprise polymerases having altered nucleotide incorporation kinetics and are linked to an energy transfer donor moiety, and nucleotide molecules linked with at least one energy transfer acceptor moiety. The donor and acceptor moieties undergo energy transfer when the polymerase and nucleotide are proximal to each other during nucleotide binding and/or nucleotide incorporation. As the donor and acceptor moieties undergo energy transfer, they generate an energy transfer signal which can be associated with nucleotide binding or incorporation. Detecting a time sequence of the generated signals, or the change in the signals, can be used to determine the order of the incorporated nucleotides, and can therefore be used to deduce the sequence of the target molecule.

Methods and apparatus for single molecule sequencing using energy transfer detection

The present disclosure provides a method for sequencing nucleic acids. The method can include polymerase catalyzed incorporation of nucleotides into a nascent nucleic acid strand against a nucleic acid template, wherein the polymerase is attached to a charge sensor that detects nucleotide incorporation events. One or more non-natural nucleotide types that each produce a unique signatures at the charge sensor can be used to uniquely identify different nucleotides in the template nucleic acid.
