PCR Annealing Temperature Calculator: Above mentioned is one of the best calculators that determine the annealing temperature in PCR. Here you will check about what is PCR and how to find annealing temperature and its formula. You can also get the solved example questions.

What is PCR Annealing Temperature?

In general, the annealing temperature is a temperature at which the primers bind to the complementary region on the target DNA. It depends on the length of primers, GC content and specificity.

The annealing temperature is a temperature which is lower than the melting temperature which facilities primer binding.


Annealing Temperature Formula

The formula to find annealing temperature is here.

Ta = 0.3 x Tmp + 0.7 x Tmt - 14.9

FAQ's on PCR Annealing Temperature Calculator

1. What does annealing temperature depend on?

The annealing temperature depends on primer melting temperature and target melting temperature.


2. What is the difference between annealing temperature and melting temperature?

The annealing temperature is the temperature where primers successfully bind. Melting temperature is the temperature where primers get fall off from DNA.


3. What is PCR?

PCR acronym is a polymerase chain reaction which is the most groundbreaking technique in biology. The main principle of PCR is to reduce the replication process of DNA in a vial and it allows to repeat several times.


4. How to find annealing temperature in PCR?

The annealing temperature of the primers in a PCR cycle can be calculated with less stable primer, melting temperature of target DNA. The annealing temperature formula is Ta = 0.3 x Tmp + 0.7 x Tmt - 14.9.
