Abstract: In some embodiments, the disclosure relates generally to methods as well as related compositions, systems, kits and apparatus comprising linking proteins to target compounds and/or to locations of interest using tethers. For example, the tether can be used to link the protein to a target compound, for example, to link an enzyme to a substrate. Similarly, the tether can be used to link the protein at or near a desired location on a surface. In one group of embodiments, the tether includes a polynucleotide and the target compound or location on the surface includes another polynucleotide that is capable of hybridizing to the tether. In such embodiments, the tether can be used to link the protein to the target compound or location using nucleic acid hybridization.

Abstract: Provided herein are compositions and systems for use in polymerase-dependent, nucleotide transient-binding methods. The methods are useful for deducing the sequence of a template nucleic acid molecule and single nucleotide polymorphism (SNP) analyses. The methods rely on the fact that the polymerase transient-binding time for a complementary nucleotide is longer compared to that of a non-complementary nucleotide. The labeled nucleotides transiently-binds the polymerase in a template-dependent manner, but does not incorporate. The methods are conducted under any reaction condition that permits transient binding of a complementary or non-complementary nucleotide to a polymerase, and inhibits nucleotide incorporation.

Abstract: In some embodiments, the disclosure relates generally to methods, as well as related compositions and kits for recombinase-mediated nucleic acid amplification, such as recombinase-polymerase amplification (RPA), of a nucleic acid template using at least one blocked primer that contains a 5′ domain, at least one nucleotide that is cleavable by an RNase H enzyme, a 3′ domain, wherein the primer is not extendable by a polymerase, and wherein the 3′ domain has a length of 7-100 nucleotides, for example 10-30 nucleotides. These methods and the use of a blocked primer reduce or eliminate non-specific amplification products, such as primer dimers, which are generated in RPA reactions.

Abstract: In some embodiments, methods for obtaining sequence information from a nucleic acid template linked to a support include hybridizing a first primer to a template strand linked to a support, sequencing a portion of the nucleic acid template, thereby forming an extended first primer product that is complementary to a portion of the nucleic acid template, In some embodiments, the method further includes introducing a nick into a portion of the template strand that is hybridized to the extended first primer product, degrading a portion of the template strand from the nick using a degrading agent, where a portion of the extended first primer remains hybridized to an undegraded portion of the template strand, and sequencing at least some of the single-stranded portion of the extended first primer by synthesis.
