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.
Abstract:
Methods of producing substrates having selected active chemical regions by employing elements of the substrates in assisting the localization of active chemical groups in desired regions of the substrate. The methods may include optical, chemical and/or mechanical processes for the deposition, removal, activation and/or deactivation of chemical groups in selected regions of the substrate to provide selective active regions of the substrate.
Abstract:
Compositions that include DNA polymerases having increased residence times for nucleotide analogues, particularly modified recombinant Φ29-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 α-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.
