| Enzymes | Buffer | Temperature | Purpose |
| EcoRI, XbaI | Low | 37°C | To create a "Front Vector" |
| EcoRI, SpeI | Low | 37°C | To create a "Front Insert" |
| SpeI, PstI | Medium | 37°C | To create a "Back Vector" |
| XbaI, PstI | Low | 37°C | To create a "Back Insert" |
| EcoRI, PstI | Promega® Buffer H | 37°C | To excise entire insert or validate part size |
