    摘要: Dimeric and trimeric nucleic acid dyes, and associated systems and methods are provided. Such a dye may form a hairpin-like structure that enables it to stain nucleic acids via a release-on-demand mechanism, for example. Such a dye may have low background fluorescence in the absence of nucleic acids and high fluorescence in the presence of nucleic acids, upon binding therewith, for example. A dye provided herein may be useful in a variety of applications, such as in DNA quantitation in real-time PCR, for example.

    IPC分类号: C12P19/34 C07H21/00

    摘要: An embodiment of the invention discloses new methods for designing labeled nucleic acid probes and primers by labeling oligonucleotides with a plurality of spectrally identical or similar dyes and optionally with one or more quencher dyes. Oligonucleotides labeled in accordance with some embodiments of the invention exhibit a detectable increase in signal, for example, fluorescent signal when the labeling dyes are separated from one another. Methods for separating the dye include cleaving the labeled oligonucleotides include using enzymes that have 5′-exonuclease activity. In one embodiment nucleic acid primers of the present invention may fluoresce upon hybridization to a target sequence and incorporation into the amplification product. Nucleic acid probes and primers of the present invention have wide applications ranging from general detection of a target nucleic acid sequence to clinical diagnostics. Major advantages of the oligonucleotides including nucleic acid probes and primers of many embodiments of the present invention are their synthetic simplicity, spectral versatility and superior fluorescent signal.
