    • A bioluminescent stem-loop probe, compositions containing bioluminescent stem-loop probes and methods of using the same are disclosed. The bioluminescent stem-loop probe can include a hairpin-loop sequence comprising a sequence complementary to a biological target sequence; a bioluminescent marker coupled to the hairpin-loop sequence; and a quencher coupled to the hairpin-loop sequence. The hairpin-loop sequence can be between the bioluminescent marker and the quencher. The bioluminescent stem-loop probe can be capable of switching between a closed configuration and an open configuration, and the quencher can reduce a bioluminescent output of the bioluminescent marker when the probe is in the closed configuration. Also disclosed are bioluminescent stem-loop probes where more than one hairpin-loop sequence-quencher complex is coupled to each bioluminescent marker.
    • 公开了一种生物发光茎环探针,含有生物发光茎环探针的组合物及其使用方法。 生物发光茎环探针可以包括包含与生物靶序列互补的序列的发夹环序列; 偶联到发夹环序列的生物发光标记; 和与发夹环序列偶联的猝灭剂。 发夹环序列可以在生物发光标记和猝灭剂之间。 生物发光茎环探针能够在闭合构型和开放构型之间切换,并且当探针处于封闭构型时,猝灭剂可以减少生物发光标记的生物发光输出。 还公开了生物发光茎环探针,其中多于一个发夹环序列猝灭剂复合物与每个生物发光标记偶联。
