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 from fluorescent reporter labels by any energy-transfer mechanism, such as FRET.
Fluorescence quencher compositions are useful in preparing quencher labelled biomolecules for various molecular biology assays based on fluorescence detection.

双重重氮基、三芳基和芳基重氮-N-芳基苯酚盐猝灭基团,通过带电子吸引和电子给予取代基团引起芳基/重氮环系统极性,当连接到生物分子如多核苷酸、核苷、核苷酸和多肽时,可作为标签。这些猝灭基团是非荧光的,并通过任何能量转移机制(如FRET)从荧光报告标签吸收能量。荧光猝灭剂组合物在制备带有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分析中,非常有用。
