    • Dark quencher constructs, termed "multi-chromophoric quenchers" are described herein that comprise at least two dark quenching moieties, which can be the same or different, linked together by at least owe multivalent linking moiety. The structure of the multi-chromophoric quenchers can be varied to selectively enhance quenching within a specific range of reporter emission wavelengths. This can be accomplished by linking together, into a single molecule, two or more identical quenchers, by reacting the quenchers with a multivalent tinker. The structure of the multi-chromophoric quencher can 0lso be varied to quench a broader range of reporter emission' wavelengths than previously possible. This can be accomplished by linking together, into a single molecule, two or more different quenchers, by reacting the quenchers with a multivalent linker. The structure of the multi-chromophoric quencher can also be varied to simultaneously broaden the absorption range and increase the total absorption within the absorption range. This can be done by combining the two concepts described above. In other words, multiple types of quenching moieties can be employed to increase the absorption range and a multiple number of each type of quenching moiety can be used to increase the total absorptivity within the absorption range. The multi-chromophoric quenchers can be tethered to probes for biomolecules, insoluble supports and/or fluorescent dyes for use in a wide variety of biomolecular assays.
    • 本文描述了称为“多发色猝灭剂”的暗猝灭剂构建体,其包含至少两个可由相同或不同的至少两个猝灭部分,通过至少多余的多价连接部分连接在一起。 可以改变多发色猝灭剂的结构以选择性地增强在特定范围的报道发射波长内的猝灭。 这可以通过将猝灭剂与多价修补剂反应来连接在一起成为单个分子,两个或多个相同的猝灭剂来实现。 多发色猝灭剂的结构也可以改变,以猝灭比之前可能的更广泛的报告基因发射波长。 这可以通过将猝灭剂与多价连接体反应来连接在一起成为单个分子,两个或多个不同的猝灭剂。 多发色猝灭剂的结构也可以改变,以同时扩大吸收范围并增加吸收范围内的总吸收。 这可以通过组合上述两个概念来完成。 换句话说,可以使用多种类型的淬灭部分来增加吸收范围,并且可以使用多个每种类型的淬灭部分来增加吸收范围内的总吸收率。 多发色猝灭剂可以束缚于用于生物分子,不溶性支持物和/或荧光染料的探针,用于各种各样的生物分子测定。
