The difference between the maximum and minimum annealing temperatures is commonly
between 5°C and 10°C starting with a maximum temperature that is 2°C above the higher
primer melting temperature (T
m
). For example, if the T
m
of Primer 1 is 60°C and the T
m
of
Primer 2 is 54°C, set the max temperature to 62°C and the min temperature to around 52°C.
