How to calculate melting temperature primer
WebCalculate and return the Tm using the ‘Wallace rule’. Tm = 4 degC * (G + C) + 2 degC * (A+T) The Wallace rule (Thein & Wallace 1986, in Human genetic diseases: a practical approach, 33-50) is often used as rule of thumb for approximate Tm calculations for primers of 14 to 20 nt length.
