WebbReal-time PCR steps. The first step in a real-time PCR reaction is the conversion of RNA to complementary DNA (cDNA) – this process is known as reverse transcription (Figure 1). The next step uses fluorescent reporters and a PCR reaction to amplify and detect specific genes (Figure 1). WebbEach cycle of polymerase chain reaction has three steps. They are: Denaturation: The first step in PCR is denaturation. Denaturation is required to separate the double-stranded …

PCR amplifies a specific region of a DNA strand (the DNA target). Most PCR methods amplify DNA fragments of between 0.1 and 10 kilo base pairs (kbp) in length, although some techniques allow for amplification of fragments up to 40 kbp. The amount of amplified product is determined by the available substrates in the reaction, which becomes limiting as the reaction progresses. A basic PCR set-up requires several components and reagents, including: WebbFor efficient endpoint PCR with fast and reliable results, here are five key steps to consider: Step 1 DNA isolation Step 2 Primer design Step 3 Enzyme selection Step 4 Thermal …
