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). WebApplicazioni della denaturazione del DNA. Questo processo può essere utilizzato per analizzare taluni aspetti del DNA. Poiché l'appaiamento citosina/guanina è più forte di quello adenina/timina, la quantità di CG in un genoma può essere stimata misurando la temperatura di melting di tale genoma (risulterà più alta, a parità di lunghezza, in quei … fifth circle: wrath and sloth
