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: 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: Low non-specific binding supports and formulations for performing solid-phase nucleic acid hybridization and amplification are described that provide improved performance for nucleic acid detection, amplification, and sequencing applications. These supports exhibit a high Contrast-to Noise Ratio (CNR), facilitating more accurate data collection and more accurate sequence reads.
