    摘要: 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.

    摘要: The quality of information from single molecule analyses is improved by employing a method in which a single molecule reaction carried out within an optical confinement is monitored, the single molecule reaction is halted, and data from the optical confinement is obtained while the reaction is not occurring. Characteristic optical behavior observed while the reaction is halted is used to improve the quality of information obtained during the single molecule reaction, for example, by correcting the reaction data, excluding the reaction data, or providing a confidence level to the reaction data.
