Abstract:
Labeled nucleotide analogs used in place of naturally occurring nucleoside triphosphates or other analogs in template directed nucleic acid synthesis reactions and other nucleic acid reactions, and various analyses based thereon, including DNA sequencing, single base identification, hybridization assays and others.
Abstract:
Compositions, kits, methods and systems for nucleotide sequencing comprising producing polymerase reactions that exhibit two kinetically observable steps within an observable phase of the polymerase reaction. Two slow step systems can be produced, for example, by selecting the appropriate polymerase enzyme, polymerase reaction conditions including cofactors, and polymerase reaction substrates including the primed template and nucleotides.
Abstract:
Compositions, methods, substrates and systems for use in analysis of single molecule reactions and particularly single molecule nucleic acid sequence analysis. Compositions that include non-reactive, distinguishable or undetectable competitive substrates for the reaction system of interest are provided, as well as their use in systems and substrates for such applications, such compounds typically preferably polyphosphate chains or analogous structures.
Abstract:
Compositions that include DNA polymerases having increased residence times for nucleotide analogues, particularly modified recombinant F29-type DNA polymerases with such increased residence times, are provided. Methods of making the polymerases and of using the polymerases in sequencing and DNA amplification are also provided. Compositions including a-thiophosphate nucleotide analogues with four or more phosphate groups are described, as are methods for determining the sequence of nucleic acid molecules using such analogues.
Abstract:
Compositions that include polymerases with features for improving entry of nucleotide analogues into active site regions and for coordinating with the nucleotide analogues in the active site region are provided. Methods of making the polymerases and of using the polymerases in sequencing and DNA replication and amplification as well as kinetic models of polymerase activity and computer-implemented methods of using the models are also provided.
