  • Publication number: 20130116141
    Abstract: The present invention provides methods and systems for real-time measurements of PCR with multiplexing capability. Certain embodiments relate to methods and systems that use fluorescently encoded superparamagnetic microspheres for the immobilization of amplification products during the PCR process, and an imaging chamber of a measurement device that is also capable of controllable thermal cycling for assisting the PCR process.

  • Publication number: 20130085078
    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.

  • Publication number: 20100330574
    Abstract: Methods and compositions for nucleic acid amplification, detection, and genotyping techniques are disclosed. In one embodiment, a nucleic acid molecule having a target-specific primer sequence; an anti-tag sequence 5? of the target-specific primer sequence; a tag sequence 5? of the anti-tag sequence; and a blocker between the anti-tag sequence and the tag sequence is disclosed. Compositions containing such a nucleic acid molecule and methods of using such a nucleic acid molecule are also disclosed.
