The annealing temperature during a polymerase chain reaction determines the specificity of primer annealing. The melting point of the primer sets the upper limit on annealing temperature. At temperatures just below this point, only very specific base pairing between the primer and the template will occur. At lower temperatures, the primers bind ...
The annealing temperature during a polymerase chain reaction determines the specificity of primer annealing. The melting point of the primer sets the upper limit on annealing temperature.

Touchdown PCR (Step-down PCR): a variant of PCR that aims to reduce nonspecific background by gradually lowering the annealing temperature as PCR cycling progresses. The annealing temperature at the initial cycles is usually a few degrees (3–5 °C) above the T m of the primers used, while at the later cycles, it is a few degrees (3–5 °C ...
In touchdown PCR, the annealing temperature is gradually decreased in later cycles. The annealing temperature in the early cycles is usually 3–5 °C above the standard T m of the primers used, while in the later cycles it is a similar amount below the T m. The initial higher annealing temperature leads to greater specificity for primer ...
Pairs of primers should have similar melting temperatures since annealing during PCR occurs for both strands simultaneously, and this shared melting temperature must not be either too much higher or lower than the reaction's annealing temperature. A primer with a T m (melting temperature) too much higher than the reaction's annealing ...
This difference enables setting the annealing temperature such that the primer will anneal to its target sequence, but not to other chimeric primers. [12] Blocked-cleavable primers: a method known as RNase H-dependent PCR (rhPCR), [13] utilizes a thermostable RNase HII to remove a blocking group from the PCR primers at high temperature. This ...
The primer design for all primers pairs has to be optimized so that all primer pairs can work at the same annealing temperature during PCR. Multiplex-PCR was first described in 1988 as a method to detect deletions in the dystrophin gene. [1] It has also been used with the steroid sulfatase gene. [2]
