How to calculate melting temperature primer
WebThe melting temperature depends on both primer length and sequence. A good rule of thumb for calculating melting temperatures is 4°C* (# G/C nucleotides) + 2°C* (# A/T … 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.
