Use the NEB Tm calculator to determine the optimal annealing temperature.At the correct T a, primers will not melt off the target DNA and primarily 100% homologous primer–target combinations will occur.The optimal annealing temperature depends primarily on length and base composition of the PCR primer and can vary from 50 C to 72 C, or even beyond. Forums pour discuter de rature, voir ses formes composées, des exemples et poser vos questions. The annealing temperature is the temperature used in the annealing step of a PCR reaction, which is highly dependent on the Tm of primers.Based on each primer’s calculated melting tempera-ture, a gradient temperature range from 55 – 67 °C was selected for the optimization process.
