SpletThe results of a sample annealing temperature optimization experiment are shown in Figure 2. Fig. 2. Annealing temperature optimization. An annealing temperature gradient from 55 to 72°C was performed. The 62.2°C reaction gave the lowest Cq value and was selected as the annealing temperature for this assay. Splet30. avg. 2006 · The thumbrule for calculating the annealing temperature for a PCR primer is Tm (°C) = 81.5 + 0.41 (%GC) - (675/N) where %GC is the percentage of G and C nucleotides in the oligo and N is the length of the oligo given in nucleotides. Example calculation: Oligo: 5'-TTAAAATGATAACCATCTCGC-3' Tm = 81.5 + 0.41 (33.3) - (675/21)

Splet22. jun. 2024 · A longer strand and a higher guanine-cytosine (GC) content are favorable for a higher melting temperature. The annealing temperature is the temperature used in the annealing step of a PCR reaction, which is highly dependent on the Tm of primers. The annealing temperature should be low enough to allow both forward and reverse primers …
