Preparative Restriction Digest
Reagents
| 10.0 µL | 10x NEBuffer 2 |
| 1.0 µL | 100x BSA |
| 5 - 10 µg | Plasmid DNA |
| 2.0 µL | EcoRI or XbaI |
| 2.0 µL | PstI or SpeI |
| to 100 µL | Aqua dest. |
| 1/10 vol | 10X Antarctic Phosphatase |
Procedure
- Mix all reagents (except for Antarctic Phosphatase) in an 1.5 mL Eppendorf-tube and incubate at 37 °C over night.
- On the next day, heat inactivate restriction enzymes at 80°C for 20 min.
- Add 1/10 volume of 10X Antarctic Phosphatase and mix. Incubate at 37 °C for 15 min for 5' extensions.
- Heat inactivate phosphatase at 70 °C for 5 min.
- Run gel and perform a gelextraction.
