WebThe simplest method in estimating primer T m is by the number of nucleotides present in the DNA oligo, using the formula: Tm = 4 (G + C) + 2 (A + T) Since the salt concentration (Na +) of the reaction impacts primer annealing, T m can be more accurately calculated with the formula: Tm = 81.5 + 16.6 (log [Na+]) + 0.41 (%GC) – 675/primer length WebThe determination of the amplicon size is, in part, dependent on the method to be used for analysis. When visualizing PCR fragments by gel electrophoresis, the PCR fragment needs to be large enough to be stained efficiently using a DNA binding dye and fit within the range of the chosen artificial size marker.
