Abstract:
Provided are compositions comprising modified recombinant polymerases that exhibit branching fractions that are less than the branching fractions of the polymerases from which they were derived, or branching fractions that are less than about 25% for a phosphate-labeled nucleotide analog. Also provided are compositions comprising modified recombinant polymerases that exhibit closed polymerase/DNA complexes with increased stability relative to the parental polymerase. Also provided are compositions comprising modified recombinant polymerases that exhibit decreased rate constants relative to the parental polymerases. Provided are methods for generating polymerases with the aforementioned phenotypes. Provided are methods of using such polymerases to make a DNA or to sequence a DNA template.
Abstract:
The present invention provides methods and compositions for performing illuminated reactions, particularly sequencing reactions, while mitigating and/or preventing photodamage to reactants that can result from prolonged illumination. In particular, the invention provides methods and compositions for incorporating photoprotective agents into conjugates comprising reporter molecules and nucleoside polyphosphates.
