    • A real time Taq-Man PCR assay for detecting multiple serotypes of human papillomavirus (HPV) wherein the number of serotypes detected exceeds the number of colorimetric channels for detection. A biological sample is combined with three oligonucleotide primer/probe sets such that the probes and primers anneal to a target sequence. Each primer/probe set is at least preferential for a specific serotype of an organism. The first and second primer/probe sets are degenerate with respect to each other. The third primer/probe set is not degenerate with respect to the first and second primer/probe sets and discriminates for a third serotype. The third primer/probe set has a signal moiety that emits signal at a wavelength that is the same or different from the wavelength emitted by the signal moiety of the degenerate primer/probe set probes. The target sequences, if present, are amplified and detected.
    • 用于检测人乳头状瘤病毒(HPV)的多种血清型的实时Taq-Man PCR测定法,其中检测的血清型数量超过用于检测的比色通道的数量。 将生物样品与三种寡核苷酸引物/探针组合,使得探针和引物与靶序列退火。 每个引物/探针组对于生物的特定血清型至少是优选的。 第一和第二引物/探针组相对于彼此退化。 第三引物/探针组相对于第一和第二引物/探针组不退化,并鉴别第三血清型。 第三引物/探针组具有在与简并引物/探针组探针的信号部分发射的波长相同或不同的波长处发射信号的信号部分。 靶序列(如果存在)被扩增和检测。

    • For use in nucleic acid amplification reactions, the detector oligonucleotides of the invention comprise a target binding sequence which is at least partially the same as the target binding sequence of an amplification primer present in the target amplification reaction, so that the detector oligonucleotide and the amplification primer compete for hybridization to the same sequence in the target. Hybridization of the amplification primer to the target upstream from the detector oligonucleotide generates a nickable restriction endonuclease recognition site. When this site is nicked and strand displacement occurs from the nick, both the 3′ end of the amplification primer and the detector oligonucleotide are displaced. The displaced detector oligonucleotide may then be detected as an indication of the presence of the target sequence, for example by unfolding of a fluorescently labeled secondary structure present in the detector oligonucleotide to reduce fluorescence quenching.
    • 为了用于核酸扩增反应,本发明的检测寡核苷酸包含与目标扩增反应中存在的扩增引物的靶结合序列至少部分相同的靶结合序列,使得检测寡核苷酸和扩增 引物竞争与目标中相同序列的杂交。 扩增引物与检测寡核苷酸上游的靶的杂交产生可切口的限制性内切核酸酶识别位点。 当该位点被切口并且从切口发生链置换时,扩增引物的3'末端和检测器寡核苷酸都被置换。 然后可以将位移的检测器寡核苷酸作为目标序列存在的指示进行检测,例如通过解折叠存在于检测器寡核苷酸中的荧光标记的二级结构以减少荧光猝灭。
