BHQTM Probes are traditional, linear, dual-labeled FRET probes with a fluorophore and a quencher covalently linked to the 5’ and 3’ ends, respectively. They are typically 20 to 30 bases in length. The 5' exonuclease activity of Taq polymerase triggers the release of a fluorescent dye upon hybridization of the probe with its complementary sequence, resulting in the cleavage of the dye. BHQ Probes are the best option for locating and measuring the number of specific target sequences.
