Abstract: The invention relates to compounds, methods and compositions for improving on nucleic acid polymerization, including DNA replication by in vitro primer extension to generate, for example, polymers for nanopore-based single molecule sequencing of a DNA template. A nucleic acid polymerase reaction composition is provided with polymerization enhancement moieties, which allows enhanced DNA polymerase activity with nucleotide analogs, resulting in improved length of primer extension products for sequencing applications.

Abstract: Methods and related products are disclosed that improve the probability of interaction between a target molecule and a nanopore by capturing the target molecule on a surface comprising the nanopore. The captured target molecule, the nanopore, or both, are able to move relative to each other along the surface. When the leader of the target molecule is in proximity with the nanopore, interaction of the target portion of the target molecule with the nanopore occurs, thereby permitting sensing of the target portion. Confining the target molecule and nanopore in this manner leads to significantly enhanced interaction with the nanopore.

Abstract: Nucleic acid sequencing methods and related products are disclosed. Methods for sequencing a target nucleic acid comprise providing a daughter strand produced by a template-directed synthesis, the daughter strand comprising a plurality of subunits coupled in a sequence corresponding to a contiguous nucleotide sequence of all or a portion of the target nucleic acid, wherein the individual subunits comprise a tether, at least one probe or nucleobase residue, and at least one selectively cleavable bond. The selectively cleavable bond(s) is/are cleaved to yield an Xpandomer of a length longer than the plurality of the subunits of the daughter strand, the Xpandomer comprising the tethers and reporter elements for parsing genetic information in a sequence corresponding to the contiguous nucleotide sequence of all or a portion of the target nucleic acid. Reporter elements of the Xpandomer are then detected.
