WebIn this step, the PCR mixture is incubated at the extension temperature (generally 72°C) for a final 5–15 minute period. The duration of this final step also depends on the amplicon length and composition and should be optimized to ensure full-length polymerization and good yield of the target DNA ( Figure 8 ). WebGradient PCR is a technique that allows the empirical determination of an optimal annealing temperature using the least number of steps. This optimization can often be achieved in one experiment....
