Since its introduction in 1985, PCR (polymerase chain reaction) has had a profound impact on life sciences and is widely used in medical diagnosis, forensic testing and other fields. PCR uses primers and heat-resistant DNA polymerase to achieve efficient DNA amplification through three steps: denaturation, annealing and extension. Conventional PCR reactions include DNA templates, primers, DNA polymerases, dNTPs and a buffer system containing magnesium ions. Modern PCR reagents usually pre-config
