Restriction Enzyme Digestion

protocol description

Theory

How it works

Practice

  • Master mix preparation
2.0μl of DNA
0.5μl of each restriction enzyme (or the respective amount of water for the control with uncut plasmids)
0.1μl of BSA - acetylated Bovine Serum Albumin enhances the performance of restriction enzymes
5.9μl of water
1.0μl of 2×NEBuffer
  • Check for the compatibility of restriction enzymes chosen

To check if the two selected restriction enzymes can perform effective catalysis in the same solution, go to the website of [http://www.neb.com New England Biolabs] → select [http://www.neb.com/nebecomm/DoubleDigestCalculator.asp? Double Digest Finder] → choose which restriction enzymes you want to use → follow the digest recommendations.

  • Procedure
  1. incubate at 37°C for 2 hours
  2. perform gel electrophoresis (10μl of DNA-restriction enzyme mixture in each well)
  3. compare with predicted fragment sizes

Safety

The safety implication of the procedure.
