Bis-diazo, triaryl and aryldiazo-N-arylphenazonium quencher moieties, substituted with electron-withdrawing and electron-donating substituents which induce polarity in the delocalized aryl/diazo ring systems, are useful as labels when attached to biomolecules such as polynucleotides, nucleosides, nucleotides and polypeptides. The quencher moieties are non-fluorescent and accept energy transfer from fluorescent reporter labels by any energy-transfer mechanism, such as FRET.
Fluorescence quencher compositions are useful in preparing quencher labeled biomolecules for various molecular biology assays based on fluorescence detection.
双重重氮基团、三芳基和芳基重氮基-N-芳基苯并咪唑猝灭剂基团,被置换为电子吸引和电子给予取代基,这些基团在离域芳基/重氮环系统中引起极性,当附着在生物分子如多核苷酸、核苷、核苷酸和多肽时,有用作为标记。猝灭剂基团是非荧光的,并通过任何能量传递机制(如FRET)从荧光报告标记接受能量传递。荧光猝灭剂组合物在制备猝灭剂标记的生物分子用于基于荧光检测的各种分子生物学测定中是有用的。
