Abstract: Provided herein are fluorescently-labeled nucleotide conjugates for nucleic acid analysis. Also provided are reagents used for forming binding complexes between a fluorescently-labeled nucleotide conjugate and a target nucleic acid sequence in the presence of one or more reagents disclosed herein. Binding complexes can be detected in the presence of the one or more reagents. For example, the one or more reagents may contain a photobleaching reducing agent configured to reduce photobleaching resulting from use of the fluorescently-labeled nucleotide conjugate to form the binding complex in a nucleic acid analysis. Such nucleic acid analysis may be used to identify sites of nucleobase binding or incorporation between the target nucleic acid sequence and one or more nucleotide moieties of the fluorescently-labeled nucleotide conjugate in a nucleic acid sequence reaction.

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.
