Definitions
- kits useful for carrying out the various methods described herein.
- the kits can comprise a first signal-quencher probe pair and at least a second signal quencher probe pair, where the quencher probe ofthe signal-quencher probe pair having the lowest T m is optional, h some embodiments, the kits can comprise from 2 to 10 different signal-quencher probe pairs.
- all ofthe signal probes can bear indistinguishable labels.
- at least one signal probe can bear a distinguishable label.
- FIG. 6A illustrates an example where the signal-quencher probe pair hybridizes to a target sequence present on the same strand of a polynucleotide
- Nucleobase means those naturally occurring and those synthetic heterocyclic moieties commonly known to those who utilize nucleic acid or polynucleotide technology or utilize polyamide or peptide nucleic acid technology to thereby generate polymers that can hybridize to polynucleotides in a sequence-specific manner.
- Polynucleotide or Oligonucleotide Mimic refers to a nucleobase polymer or oligomer in which one or more ofthe backbone sugar-phosphate linkages is replaced with a sugar-phosphate analog.
- Such mimics are capable of hybridizing to complementary polynucleotides or oligonucleotides, or polynucleotide or oligonucleotide analogs or to other polynucleotide or oligonucleotide mimics, and may include backbones comprising one or more ofthe following linkages: positively charged polyamide backbone with alkylamine side chains as described in U.S. Patent No. 5,786,461; U.S. Patent No.
- amide backbones see, e.g., Lebreton, 1994, Synlett. February, 1994:137
- methylhydroxyl amine backbones see, e.g., Vasseur et al., 1992, J. Am. Chem. Soc. 114:4006
- 3'- thioformacetal backbones see, e.g., Jones et al., 1993, J. Org. Chem. 58:2983
- sulfamate backbones see, e.g., U.S. Patent No. 5,470,967). All ofthe preceding references are herein incorporated by reference.
- R is -OR' or -NR'R', where each R' is independently hydrogen or ( -C ⁇ ) alkyl, preferably hydrogen.
- TMA Transcription-Mediated Amplification
- Q-beta Q-beta replicase amplification
- RCA Rolling Circle Amplification
- PCR Asynchronous PCR
- Quenching occurs when the quencher probe is hybridized in close proximity to the signafprobe, thereby bringing the quencher label sufficiently close to the signal label to result in a measurable decrease in the quantity of detectable signal produced by the signal label.
- quenching will be affected by factors such as the identity ofthe quencher and signal label, how the signal-quencher probe pair has been designed to hybridize to the target sequence, as well as the proximity ofthe signal probe to the quencher probe (i.e., whether or not the signal probe and quencher probe are contiguous or separated by one or more nucleotides).
- the signal label is a moiety that produces a differential signal when in the presence of single-stranded versus double-stranded polynucleotides.
- Moieties having this property include, by way of example and not limitation, dyes that intercalate between base pairs of double-stranded polynucleotides such as double-stranded DNA, and dyes that bind the minor groove of double-stranded polynucleotides such as double-stranded DNA (MGB dyes). Numerous such intercalating and MGB dyes are known.
- Hairpin self-indicating probes are well-known in the art (see, e.g., Tyagi et al., 1996, Nature Biotechnology 14:303-308; Nazarenko et al., 1997, Nucl. Acids Res. 25:2516-2521 for reviews see: Tan et al., 2000, Chem. Eur. J. 6:1107; Fang et al., 2000, Anal. Chem. 72:747A; all of which are incorporated herein by reference) and have a nucleobase sequence capable of adopting a hairpin conformation in solution.
- the detectable signal produced by the signal labels ofthe signal probes is monitored as a function of temperature.
- the detection system used will depend upon the nature ofthe detectable signal produced by the signal probe label, and will be apparent to those of skill in the art.
- Devices for measuring emissions from fluorescent signal labels (at one or more wavelengths) are available commercially, as are devices for measuring emissions from fluorescent signal labels (at one or more wavelengths) at varying temperatures.
- Such devices include, by way of example and not limitation, the LightCyclerTM instrument available from Roche (formerly from Idaho Technologies) and PrismTM 7700, 7900, 7000 Sequence detector instruments available from Applied Biosystems (Foster City, CA).
