    Abstract: The present disclosure provides compositions, methods, kits, systems and apparatus that are useful for nucleic acid polymerization. In particular, modified polymerases and biologically active fragments thereof are provided that allow for nucleic acid amplification. In some aspects, the disclosure provides modified polymerases having lower systematic error as compared to a reference polymerase. In one aspect, the disclosure relates to modified polymerases useful for nucleic acid sequencing, genotyping, copy number variation analysis, paired-end sequencing and other forms of genetic analysis. In some aspects, the disclosure relates to modified polymerases useful for the generation of nucleic acid libraries or nucleic acid templates. In some aspects, the disclosure relates to the identification of homologous amino acid mutations that can be transferred across classes or families of polymerases to provide novel polymerases with altered properties.

    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: The present disclosure provide systems, compositions, methods, reagents, kits and products for extending a nucleic acid that includes incorporating a nucleotide residue at a terminus of a nucleic acid using a polymerase enzyme and at least one nucleotide, wherein the at least one nucleotide includes a thiophosphate moiety, and wherein the at least one nucleotide is resistant to hydrolysis by phosphatase. In some embodiments, the nucleotide incorporation can be conducted in the presence of a phosphatase. In some embodiments, the nucleotide incorporation can be conducted in the presence of at least on chelation moiety that is configured to bind an orthophosphate moiety.

    Abstract: Provided herein are systems and methods for nucleotide incorporation reactions. The systems comprise polymerases having altered nucleotide incorporation kinetics and are linked to an energy transfer donor moiety, and nucleotide molecules linked with at least one energy transfer acceptor moiety. The donor and acceptor moieties undergo energy transfer when the polymerase and nucleotide are proximal to each other during nucleotide binding and/or nucleotide incorporation. As the donor and acceptor moieties undergo energy transfer, they generate an energy transfer signal which can be associated with nucleotide binding or incorporation. Detecting a time sequence of the generated signals, or the change in the signals, can be used to determine the order of the incorporated nucleotides, and can therefore be used to deduce the sequence of the target molecule.
