Web8 aug. 2024 · In the HMD method, the Tm is determined by calculating the temperature of HMD (DT 50 ), which is the temperature at which the fluorescence intensity reaches 50% of the highest fluorescence intensity. If no protein or a denatured protein is added, the returned Tm is the initial temperature (32°C in the exemplar data). WebBasic Melting Temperature (Tm) Calculations Two standard approximation calculations are used. For sequences less than 14 nucleotides the formula is: Tm= (wA+xT) * 2 + (yG+zC) * 4 where w,x,y,z are the number of the bases A,T,G,C in the sequence, respectively. For sequences longer than 13 nucleotides, the equation used is
