The comparative threshold cycle method
WebThe COVID-19 pandemic represented a challenge for health-care systems, and a major bottleneck in SARS-CoV-2 diagnosis was the unavailability of extraction reagents. To overcome this limitation, we performed a comparative analysis to evaluate the performance of an alternative extraction protocol derived from veterinary use adapted to an open … Two strategies are commonly employed to quantify the results obtained by real-time RT-PCR; the standard curve method and the comparative threshold method. These are discussed briefly below. Standard Curve Method In this method, a standard curve is first constructed from an RNA of known concentration. See more TaqMan probes depend on the 5'- nuclease activity of the DNA polymerase used for PCR to hydrolyze an oligonucleotide that is hybridized to the target amplicon. … See more With Scorpion probes, sequence-specific priming and PCR product detection is achieved using a single oligonucleotide.
