Abstract
This application provides photoinduced electron transfer (PET) nucleic acid molecules that can be used detect and amplify nucleic acid molecules, such as target nucleic acid molecules. These PET tags can be attached to the 5′-end of a target sequence-specific primer, thereby generating a PET primer. In particular examples, a PET tag includes a 5′-labeled nucleotide that can be quenched by at least two consecutive Gs within the tag sequence, and is unquenched when the PET tag hybridizes with its complementary nucleic acid molecule. Also disclosed are methods of using PET primers in nucleic acid amplification, such as real-time PCR.
