Protected fluorescent reagent compounds and their methods of synthesis are provided. The compounds 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 compounds 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.
提供了受保护的荧光试剂化合物及其合成方法。这些化合物适用于各种基于荧光的分析方法,包括分析大量高密度的高度复用光学反应,如单分子实时核酸测序反应。这些化合物含有荧光染料元件,可在理想波长下以高灵敏度检测化合物;含有结合元件,可使化合物被目标生物大分子特异性识别;还含有保护罩元件,可减少荧光染料元件与结合的目标生物大分子之间的不良接触,从而减少荧光染料元件对结合的目标生物大分子的光损伤。
