The primer length should be between 10 and 70

WebbThe simplest method in estimating primer T m is by the number of nucleotides present in the DNA oligo, using the formula: T m = 4 (G + C) + 2 (A + T) Since the salt concentration … Webb5 sep. 2024 · Key takeaways: PCR primers should have a length between 18 and 24 nucleotides, and probes between 15 to 30 nucleotides. The optimal melting temperature (T m) of a primer is 54°C or higher. The annealing temperature (T a) of a primer is often above its Tm (of 2-5°C). The GC content of a primer should be between 40% and 60%.
