How Does QuantStudio 3 Real-Time PCR Work?

So, how does the QuantStudio 3 work its magic? Let's break down the process step-by-step. First, you'll prepare your reaction mix, which includes your sample, primers, probe or dye, and other essential reagents. Then, the reaction mix is placed into the QuantStudio 3. The system then cycles through a series of temperature changes. These temperature cycles drive the PCR process. The first step involves an initial denaturation step where the DNA is heated, separating the DNA strands. Next, the primers bind to the target DNA during the annealing phase. Finally, the DNA polymerase extends the primers, creating copies of the target DNA during the extension phase. As the DNA amplifies, fluorescent signals are generated. The fluorescent signals can be measured by the optical system in real-time. The system measures the fluorescence signals during each cycle, providing information on the amount of DNA amplified. The software then analyzes these signals to generate data, such as amplification plots and quantification results. This data reveals the concentration of your target DNA in the sample.
