Tm of long PCR primers

Calculate the Tm (Melting Temperature, in Celsius degrees) of your primers: For long primers use the formula :  Tm = 64.9 + 41(((G+C) -16.4)/N) Where N is the primer length in bases. This formula can also be used for shorter primers and is more accurate for long primers than the short primer formula.
