PCR error calculator

Please enter the following values to determine the percentage of PCR products containing an error

Length of PCR product in bp:

Fidelity value of DNA polymerase
Phusion High-Fidelity DNA polymerase (HF Buffer; fidelity 4.4 x 10-7)
Phusion High-Fidelity DNA polymerase (GC Buffer; fidelity 9.5 x 10-7)
Pyrococcus furiosus DNA polymerase (2.8 x 10-6)
Taq DNA polymerase (2.28 x 10-5)

Number of PCR cycles:

Estimated percentage of PCR products having an error (i.e. DNA molecules with 1 error):   

Examples

How many percent of the product molecules contain an error after PCR (30 cycles) with different polymerases

Polymerase

1 kb template

3 kb template

Phusion™ High-Fidelity DNA Polymerases (HF Buffer)

1.32 %

3.96 %

PhusionT High-Fidelity DNA Polymerases (GC Buffer)

2.85 %

8.55 %

Pyrococcus furiosus DNA polymerase

8.4 %

25.2 %

Taq DNA polymerase

68.4 %

205.2 %

The table above demonstrates the low error rate of Phusion DNA Polymerase. After 30 cycles of PCR amplifying a 3 kb template, only 3.96 % of the product DNA molecules contain 1 (nucleotide) error each. This means that 96.04 % of the product molecules are entirely error-free. In contrast, after the same PCR protocol performed with Taq DNA polymerase, every product molecule contains in average 2 errors.
