    摘要: Methods are provided for reducing background signals encountered in nucleic acid hybridization assays and other assays that involve hybridization of a labeled oligomer to its complement. The method is premised on the significant reduction of signal generation that occurs when a quenchable dye-labeled oligomer forms a hybrid complex. In addition, a method is provided for enhancing the detectable signal emitted from an amplification multimer hybridized to an oligomer probe to which a quenchable dye has been conjugated through a linker such that the emission from the dye is not quenched upon hybrid complex formation. Novel oligonucleotide probes are also provided that comprise an oligomer to which has been directly or indirectly through a linker a quenchable dye.
