Method and composition for identifying cognate nucleotides in a Sequencing By Binding™ procedure, wherein one or more labeled nucleotides are detected in ternary complexes but never incorporated. Labeled nucleotides can be incorporable nucleotides that contact preformed blocked primed template nucleic acids. Alternatively, labeled nucleotides are labeled non-incorporable nucleotides. Labeled nucleotides, including labeled non-incorporable nucleotides, can be detected in ternary complexes in the same reaction mixture that incorporates a reversible terminator nucleotide to create a blocked primed template nucleic acid. Detection of ternary complexes can take place in the presence of a catalytic metal ion.

Process for cognate nucleotide detection in a nucleic acid sequencing workflow

This application provides a bead with a covalently attached chemical compound and a covalently attached DNA barcode and methods for using such beads. The bead has many substantially identical copies of the chemical compound and many substantially identical copies of the DNA barcode. The compound consists of one or more chemical monomers, where the DNA barcode takes the form of barcode modules, where each module corresponds to and allows identification of a corresponding chemical monomer. The nucleic acid barcode can have a concatenated structure or an orthogonal structure. Provided are method for sequencing the bead-bound nucleic acid barcode, for cleaving the compound from the bead, and for assessing biological activity of the released compound.

Oligonucleotide encoded chemical libraries

Method of identifying a cognate nucleotide (i.e., the 'next correct nucleotide') for a primed template nucleic acid molecule. In some embodiments, an ordered or random array of primed target nucleic acids characterized by different cognate nucleotides can be evaluated using a single imaging step to identify different cognate nucleotides for a collection of different primed template nucleic acid molecules. An optional incorporation step can follow the identifying step. A polymerase different from the ones used in the binding and examination steps can be used to incorporate a nucleotide, such as a reversible terminator nucleotide, preliminary to identification of the next cognate nucleotide.

Method and system employing distinguishable polymerases for detecting ternary complexes and identifying cognate nucleotides

Method and apparatus to facilitate separation of solution-phase components surrounding an immobilized multicomponent complex while stabilizing association of the components within the complex. The technique can be used for reducing background signal arising from the presence of non-complexed components harboring detectable labels, thereby enhancing signal-to-background ratios and allowing enhanced detection of the multicomponent complex.

Simultaneous background reduction and complex stabilization in binding assay workflows

Provided are compositions, methods and systems for determining the sequence of a template nucleic acid using a polymerase-based, sequencing-by-binding procedure. An examination step involves monitoring the interaction between a polymerase and template nucleic acid in the presence of one or more nucleotides. Identity of the next correct nucleotide in the sequence is determined without incorporation of any nucleotide into the structure of the primer by formation of a phosphodiester bond. An optional incorporation step can be used after the examination step to extend the primer by one or more nucleotides, thereby incrementing the template nucleotides that can be examined in a subsequent examination step. The sequencing-by-binding procedure does not require the use of labeled nucleotides or polymerases, but optionally can employ these reagents.
