Splet17. mar. 2024 · 1. Denaturation. The first step of PCR, called denaturation, heats the template DNA up to 95 °C for a few seconds, separating the two DNA strands as the hydrogen bonds between them are rapidly broken. 2. Annealing. The reaction mixture is then cooled for 30 seconds to 1 minute. SpletSet the annealing temperature to 5°C lower than the Tm of your primers. If you are getting non-specific PCR products, increase the annealing temperature step-wise by 1-2°C. The rate of DNA synthesis is ~1-2 …
