The present invention provides novel quencher composition comprising anthraquinone quencher moieties. The anthraquinone quencher moieties are useful as quencher labels when attached to biomolecules such as natural or modified polynucleotides, oligonucleotides, nucleosides, nucleotides, carbohydrates and peptides. For example, polynucleotides can be labeled at the 3' terminus with fluorescence quencher solid support compositions, and polynucleotides can be labeled at internally or at the 5' terminus. The detectable probes may have a format like molecular beacons, scorpion probes, sunrise probes, conformationally assisted probes and TaqMan probes.
本发明提供了包含
蒽醌淬灭剂分子的新型淬灭剂组合物。当
蒽醌淬灭剂分子连接到
生物大分子,如天然或修饰的多核苷酸、寡核苷酸、核苷酸、核苷酸、
碳水化合物和肽时,可用作淬灭剂标签。例如,可以用荧光淬灭剂固体支持物组合物在多核苷酸的 3'末端进行标记,也可以在多核苷酸的内部或 5'末端进行标记。可检测探针的形式可以是分子信标、蝎子探针、日出探针、构象辅助探针和 TaqMan 探针。
