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%. Webb21 okt. 2013 · Length: Typically, amplicons of 70–150 bp allow for enough nucleotide sequence within which the primers and probe with adequate T m can be designed.
