Description

Potato spindle tuber viroid (PSTVd) Probe Realtime RT-PCR Kit is designed for the quantitative detection of its specific DNA in a real-time PCR test using hydrolysis probes. In the amplification process, Taq DNA polymerase amplifies the DNA sample via quantitative PCR using a primer-probe set that targets its specific DNA region. At each cycle of the PCR, the 5' nuclease activity of Taq DNA polymerase degrades the bound probes, releasing the quenched specific FAM signal. The increase in FAM fluorescence measures the target gene-specific DNA amplifications. At a point where the fluorescence signal is confidently detected over the background signal, a Ct value can be determined for the FAM signal. This Ct parameter can be used to evaluate relative target abundance among samples.
