Nucleic-acid technologies: PCR
Double-quenched qPCR probes
Integrated DNA Technologies' double-quenched probes are designed to increase the accuracy and reliability of 5’ nuclease qPCR experiments.
The probe design positions an internal ZEN quencher 9 bases from the 5’ fluorophore, which when combined with the standard 3’ quencher, significantly decreases background fluorescence and increases sensitivity. Due to the incorporation of ZEN, the initial background fluorescence signal is much lower, making subsequent changes easily detectable while assay sensitivity is increased. As a result low background is obtained, even at 40 base pairs or longer, increasing specificity without loss in sensitivity or quenching efficiency. This functionality increases qPCR accuracy and sensitivity when compared to traditional probes.
