    Abstract: Nucleic acid hybridization buffer formulations and uses thereof are described that yield improvements in hybridization specificity, rate, and efficiency. The buffer formulation composition includes a target nucleic acid; at least one organic solvent having a dielectric constant in the range of no greater than 115; and a pH buffer system, wherein the target nucleic acid is attached to the surface via hybridization to a surface bound nucleic acid tethered to the surface, and wherein the hybridization of the target nucleic acid and surface bound nucleic acid has a high stringency and annealing rate.

    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.
