Restriction digestion

Materials required

  • Eppendorf tubes
  • Pipettes
  • Appropriate DNA/plasmid
  • Appropriate restriction enzymes
  • 10X buffer
  • Water

Procedures

  1. Make up 20 µl reaction mix as follows:
    • 15 µl of DNA/plasmid
    • 1 µl of restriction enzyme 1
    • 1 µl of restriction enzyme 2
    • 2 µl of 10X buffer
    • 1 µl of water
  2. Incubate at 37°C for 3 hours

Notes

  • No more than 10% of enzyme should be used for a single reaction - glycerol inhibits reaction
  • 10x buffer must be diluted to 1x i.e. 10% final volume
