    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.

    Abstract translation: 提供包含具有增加的核苷酸类似物的停留时间的DNA聚合酶的组合物,特别是具有这种增加的停留时间的经修饰的重组Phi29型DNA聚合酶。 还提供了在测序和DNA扩增中制备聚合酶和使用聚合酶的方法。 描述了包括具有四个或更多个磷酸基团的α-硫代磷酸核苷酸类似物的组合物,以及使用这种类似物确定核酸分子的序列的方法。
