Webb4 maj 2024 · PCR primers are generally designed to be 18 – 30 bp in length. Shorter primers anneal more readily to the target sequence, although they are also more likely to bind to more than one region in the genome and produce non-target amplicons. For this reason, target-specific primers are usually longer. The melting temperature (Tm) of the … Webbconsiderations should be made when designing mutagenic primers: i Both of the mutagenic primers must contain the desired mutation and anneal to the same sequence on opposite strands of the plasmid. i Primers should be between 25 and 45 bases in length, with a melting temperature (Tm) of t78°C.
