Methods and compositions for the detection and quantification of nucleic acids are provided. In certain embodiments, methods involve the use of cleavable probes capable of forming double-stranded structures, such as hairpin structures, which probes can be distinguished from one another on the basis of reporter signal, melt properties, or both.

Methods and probes for performing PCR with melt analysis for increased multiplexing

Nucleic acid constructs and methods that provide superior prevention of primer-dimers and other artifacts of false priming events are disclosed. In particular, there is disclosed a hairpin primer having a target-specific primer region, wherein the target-specific region comprises a target-binding dependent cleavage sequence; a first stem forming region 5' of the target-specific primer region; and a second stem forming region 3&#x2032; of the target-specific primer region, wherein the second stem forming region is complementary to the first stem forming region. Methods of using the hairpin primer to amplify a target nucleic acid are also disclosed.

Cleavable hairpin primers

Methods and compositions for the detection and quantification of nucleic acids are provided. In certain embodiments, methods involve the use of primers or probes that comprise a non-natural nucleotide linked to a reporter. Target nucleic acids are detected by the polymerization of a complementary probe or primer that incorporated a cognate non-natural nucleotide linked to a quencher.

Probes for improved melt discrimination and multiplexing in nucleic acid assays

Methods and compositions for the detection and quantification of nucleic acids are provided. In certain embodiments, methods involve the use of cleavable probes that comprise a ribonucleotide position that is susceptible to endoribonuclease (e.g., RNase H) cleavage in the presence of target nucleic acid molecules. Probes of the embodiments may also comprise non-natural nucleotide linked to a reporter and/or quenching moiety.

Methods and systems for magnetic mixing. Particular embodiments relate to applying a magnetic field to move a magnetically responsive component in a chamber.
