BioBrick digestion with restriction enzymes

(estimated time: 3 hours)

Materials needed:

Roche restriction enzymes thawed on ice
Roche buffer H
Pre-warmed at 37°C bath
Cut and gel-extracted vector
ddH2O

To open vectors:
- a volume containing 1 µg of purified plasmid
- 2 µl of buffer H
- 1 µl of first enzyme
- 1 µl of second enzyme
- 20 µl final volume
- incubate at 37°C for 3 hours
To excide fragments:
- 20 µl of purified plasmid when <7 µg have been extracted. A volume containing 7 µg otherwise.
- 2.5 µl of buffer H
- 1 µl of first enzyme
- 1 µl of second enzyme
- 25 µl final volume
- incubate at 37°C for 2 hours and 30 minutes
