Abstract: Multivalent binding compositions including a particle-nucleotide conjugate having a plurality of copies of a nucleotide attached to the particle are described. The multivalent binding compositions allow one to localize detectable signals to active regions of biochemical interaction, e.g., sites of protein-protein interaction, protein-nucleic acid interaction, nucleic acid hybridization, or enzymatic reaction, and can be used to identify sites of base incorporation in elongating nucleic acid chains during polymerase reactions and to provide improved base discrimination for sequencing and array based applications.

Abstract: Provided herein are engineered variants of archaeal polymerases that exhibit exonuclease-minus activity, enhanced thermostability, enhanced incorporation of 3′ modified nucleotides, improved uracil-tolerance and/or reduce sequence-specific errors in polymerase-catalyzed nucleotide binding and extension reactions relative to wild type polymerase enzymes. Also provided are uses of the engineered polymerases for forming complexed polymerases and forming binding complexes, and uses for conducting nucleic acid sequencing reactions.

Abstract: The present disclosure provides compositions comprising enzyme-based reagents, and methods using the enzyme-based reagents, for nucleic acid sequencing. The enzyme-based reagents efficiently remove sequencing read products from a first sequenced region of a template molecule, thereby reducing residual signals in a second sequenced region on the same template molecule.

Abstract: The present disclosure provides compositions and methods that employ the compositions for conducting pairwise sequencing and for generating concatemer template molecules for pairwise sequencing. The concatemers can be generated using a rolling circle amplification reaction which is conducted either on-support, or conducted in-solution and then distributed onto a support. The rolling circle amplification reaction generates concatemers containing tandem copies of a sequence of interest and at least one universal adaptor sequence. An increase in the number of tandem copies in a given concatemer increases the number of sites along the concatemer for hybridizing to multiple sequencing primers which serve as multiple initiation sites for polymerase-catalyzed sequencing reactions. When the sequencing reaction employs detectably labeled nucleotides and/or detectably labeled multivalent molecules (e.g., having nucleotide units), the signals emitted by the nucleotides or nucleotide units that participate in the parallel sequencing reactions along the concatemer yields an increased signal intensity for each concatemer.

Abstract: Methods and formulations for preparing low non-specific binding surfaces are described, and the prepared surface can provide improved performance for nucleic acid detection and base calling applications. The surface provides more accurate nucleic acid detection, enhanced contrast to noise ratio, and better data collection.
