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.

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.

Provided herein is technology relating to the amplification-based detection of bisulfite-treated DNAs and particularly, but not exclusively, to methods and compositions for multiplex amplification of low-level sample DNA prior to further characterization of the sample DNA. The technology further provides methods for isolating DNA from blood or blood product samples, e.g., plasma samples.
