A real-time polymerase chain reaction (real-time PCR), also known as quantitative Polymerase Chain Reaction (qPCR), is a laboratory technique of molecular biology based on the polymerase chain reaction (PCR). It monitors the amplification of a targeted DNA molecule during the PCR (i.e., in real time), not at its end, as in conventional PCR. Real-time PCR can be used quantitatively. As the coronavirus that causes the COVID-19 disease spreads across the world, the IAEA, in partnership with the Food and Agriculture Organization of the United Nations (FAO), is offering its support and expertise to help countries use real time reverse transcription-polymerase chain reaction (real time RT-PCR), one of the most accurate laboratory methods for detecting, tracking and. Real-Time Polymerase Chain Reaction. Real-time PCR is a quantitative method that allows the data to be compiled as the product accumulates, by detecting the signal emitted by the fluorescent probe during each amplification cycle, that is proportional to the amount of amplicons generated (the target viral DNAs contained in the sample) In real-time reverse transcription polymerase chain reaction (RT-PCR), a probe is added during the PCR process, which will fluoresce whenever a new DNA molecule is formed. The increase in viral cDNA can be followed in real-time by tracking the increase in fluorescent signal The PCR reaction mixture had a final volume of 20 μl and contained 2 μl of cDNA, 10.000-fold diluted SYBR Green solution (Molecular Probes), 0.4 mM forward and reverse primer, 0.3 mM dNTPs, 3 mM MgCl 2 and 1 U Taq polymerase (Promega). Real-time PCR data were collected on the BioRad iCycler iQ and the Corbett Research Rotor-Gene 3000 with.
