Multimeric protected fluorescent reagents and their methods of synthesis are provided. The reagents 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 reagents contain fluorescent dye elements, that allow the compounds to be detected with high sensitivity at desirable wavelengths, binding elements, that allow the compounds to be recognized specifically by target biomolecules, and protective shield elements, that decrease undesirable contacts between the fluorescent dye elements and the bound target biomolecules and that therefore decrease photodamage of the bound target biomolecules by the fluorescent dye elements. The reagents also contain coupling elements connect monomeric compounds into multimeric forms, thereby increasing brightness.
提供了多聚保护荧光试剂及其合成方法。这些试剂在各种基于荧光的分析方法中很有用,包括在高密度下分析高度多重光学反应,比如单分子实时核酸测序反应。这些试剂包含荧光染料元素,允许化合物在理想波长下以高灵敏度被检测,结合元素,允许化合物被目标生物分子特异性识别,以及保护屏障元素,减少荧光染料元素与结合的目标生物分子之间的不良接触,从而减少荧光染料元素对结合的目标生物分子的光损伤。这些试剂还包含耦合元素,将单体化合物连接成多聚形式,从而增加亮度。
