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.
本发明提供了一种新型猝灭剂组合物,包括蒽醌猝灭剂基团。当连接到生物分子(如天然或改性多聚核苷酸、寡核苷酸、核苷、核苷酸、碳水化合物和肽)时,蒽醌猝灭剂基团可用作猝灭剂标记。例如,多聚核苷酸可在3'端标记荧光猝灭剂固相支持组合物,也可在内部或5'端标记多聚核苷酸。可检测的探针可能具有类似分子信标、蝎子探针、日出探针、构象辅助探针和TaqMan探针的格式。
