The Phusion Hi-Fi PCR Master Mix has multiple components like the Phusion Hot Start II DNA Polymerase is the central enzyme. It is a polymerase enzyme with 3’ to 5’ exonuclease activity that corrects mismatched bases and therefore has low error rates than Taq polymerase. The ‘Hot Start’ part in the name refers to the modification done to enzyme to keep it inactive until the initial denaturation step so that the polymerase doesn’t amplify some other DNA at room temperature. The mix also contains dNTPs which is a given as the nucleotides are the building blocks used for extension. Another component is MgCl2 which is a cofactor required for polymerase activity, The magnesium ion helps in catalysis of the phosphodiester bond formation between nucleotides. Magnesium ions are also important to form active substrate from dNTPs which is recognized by polymerase. (The magnesium ions neutralize some of the charge of the triphosphate group so they can fit into the active site of the polymerase without hindrance) Other components in the mix are Reaction Buffer and Stabilizers. The buffer maintains the optimal pH and Ionic strength for enzyme activity. What are some factors that determine primer annealing temperature during PCR?Hugoen
