• ### How do you calculate the annealing temperature for …

The optimal annealing temperature (T a Opt) for a given primer pair on a particular target can be calculated as follows: T a Opt = 0.3 x (T m of primer) + 0.7 x (T m of product) – 14.9; where T m of primer is the melting temperature of the less stable primer-template pair, and T m of product is the melting temperature of the PCR product.

• ### Determining Annealing Temperatures for …

The length of the primer and the G and C content of the primer-DNA template duplex play critical roles in determining T m, which is calculated by the formula 4 (G+C) + 2 (A+T), and this is the rule of thumb for calculating annealing temperature.

Melting temperature is the temperature at which 50% of the oligo and its perfect complement are in duplex. PCR annealing temperature a few degree (4-6) lower than the melting temperature is usually used to increase the probability of primer binding. To calculate melting temperature or for more information, please see BioToolKit or Primo Online. Simple rule. Melting temperature (T m) = 4 ...

• ### Important instructions on annealing temperature

Example: Tm's given by the calculator are 66.5°C and 65.0°C => Use an annealing temperature of 68.0°C in the actual run. With Phire Hot Start DNA Polymerase, use primers with Tm 60°C or higher. If the amplification fails with the recommended annealing temperature, use a temperature gradient to optimize the annealing.

• ### Tm Calculator | Thermo Fisher Scientific - FR

The calculator calculates recommended T m (melting temperature) of primers and PCR annealing temperature based on the primer pair sequence, primer concentration, and DNA polymerase used in PCR. The calculator also calculates the primer length, percentage of GC content, molecular weight, and extinction coefficient.

• ### OligoCalc: Oligonucleotide Properties Calculator

The thermodynamic calculations assume that the annealing occurs at pH 7.0. The melting temperature (Tm) calculations assume the sequences are not symmetric and contain at least one G or C. The oligonucleotide sequence should be at least 8 bases long to give reasonable Tms. The accuracy of the calculation decreases after 20 nucleotides since the equations and parameters were defined with ...
