Polymerase Chain Reaction
All PCR reactions were done with DreamTaq and Phusion polymerase from Thermo Scientific.
DreamTaq polymerase
For colony PCR DreamTaq polymerase is used. As the template, the colony of interest is picked from a plate using a sterile toothpick and mixed into the reaction mixture. The cycling conditions are listed in the table below.
| Step | Temperature | Time | Number of cycles |
|---|---|---|---|
| Initial denaturation | 95 °C | 1 - 3 min | 1 |
| Denaturation | 95 °C | 30 sec | 30 |
| Annealing | Tm - 5 °C | 30 sec | |
| Extension | 72 °C | 1 min/kb | |
| Final extension | 72 °C | 10 min/kb | 1 |
Phusion polymerase
Phusion polymerase is used when high fidelity is needed for the reaction. Phusion has been used for making of the BioBricks with PCR and generating specific mutations in genes with the use of primers. The cycling program is listed in the table below.
| Step | Temperature | Time | Number of cycles |
|---|---|---|---|
| Initial denaturation | 98 °C | 30 sec | 1 |
| Denaturation | 98 °C | 10 sec | 30 |
| Annealing | Tm - 5 °C | 30 sec | |
| Extension | 72 °C | 15-30 sec/kb | |
| Final extension | 72 °C | 10 min/kb | 1 |
