The annealing temperature depends on primer length, GC content and specificity, however, it must be between 50 º C to 68 ºC, Ideally, it should be 60ºC to 64ºC. It must be 5 to 7ºC lower than the melting temperature. What happens during the annealing step in PCR?

WebThe most sophisticated T m calculations take into account the exact sequence and base stacking parameters, not just the base composition (1,2,3). The equation used is: T m = Δ H kcal ∘ C × Mol Δ S + R In ( [primer] / 2) − 273.15 ∘ C. Δ H is the enthalpy of base stacking interactions adjusted for helix initiation factors (3,4).
