Labeled nucleotide analogs comprising at least one avidin protein, at least one dye-labeled compound, and at least one nucleotide compound are provided. The analogs are useful in various fluorescence-based analytical methods, including the analysis of highly multiplexed optical reactions in large numbers at high densities, such as single molecule real time nucleic acid sequencing reactions. The analogs are detectable with high sensitivity at desirable wavelengths. They contain structural components that modulate the interactions of the analogs with DNA polymerase, thus decreasing photodamage and improving the kinetic and other properties of the analogs in sequencing reactions. Also provided are nucleotide and dye-labeled compounds of the subject analogs, as well as intermediates useful in the preparation of the compounds and analogs. Compositions comprising the compounds, methods of synthesis of the intermediates, compounds, and analogs, and mutant DNA polymerases are also provided.
提供了包含至少一种亲和素蛋白、至少一种染料标记化合物和至少一种核苷酸化合物的标记核苷酸类似物。这些类似物在各种基于荧光的分析方法中很有用,包括在高密度下对大量高度多重光学反应进行分析,例如单分子实时核酸测序反应。这些类似物在理想波长下具有高灵敏度的可检测性。它们包含调节类似物与DNA聚合酶相互作用的结构组分,从而减少光损伤,并改善测序反应中类似物的动力学和其他性质。还提供了主题类似物的核苷酸和染料标记化合物,以及在制备这些化合物和类似物中有用的中间体。还提供了包含这些化合物的组合物、合成这些中间体、化合物和类似物的方法,以及突变的DNA聚合酶。
