Abstract: Methods and compositions for the detection and quantification of nucleic acids are provided. In one embodiment, a sample is contacted with a primer and a quencher-probe complementary to a target nucleic acid. The quencher-probe is complementary to an anti-probe that comprises a reporter and is attached to a solid support. Thus, hybridized probe is cleaved with a nucleic acid polymerase having exonuclease activity to release the quencher from the probe. The presence of the target nucleic acid is then detected and/or optionally quantified by detecting an increase in signal from the fluorescent reporter on the solid support.

Abstract: Methods and compositions for the detection and quantification of nucleic acids are provided. In one embodiment, a sample is contacted with a primer complementary to a first region of a target nucleic acid and a probe complementary to a second region of the target nucleic acid downstream of the first region under conditions suitable for hybridization of the target nucleic acid with the primer and the probe. The probe in this embodiment comprises a fluorophore and is attached to a solid support. The hybridized probe is cleaved with a nucleic acid polymerase having exonuclease activity to release the reporter from the solid support. The presence of the target nucleic acid is then detected and optionally quantified by detecting a decrease in signal from the reporter on the solid support.
