DNA Digestion

Reagents and Materials

For a DNA digestion of total volume V (in μL):
  • X µl 1-520 ng.
  • 5 µl NEB2 buffer.
  • 0.5 µl 100x BSA.
  • 1 μL BB enzyme 1.
  • 1 μL BB enzyme 2.
  • (42.5-x) µl distilled water.


  1. Find appropriate enzymes(s), associated buffer, reaction temperature from NEB.
  2. Calculate the total volume of the reaction by taking the DNA volume + 1(2) μL for a single (double) digestion reaction. Divide this number by 0.8 to get the total reaction volume, V.
  3. Calculate the volume of 10mg/ml BSA and 10X digestion buffer, which are both 0.1V.
  4. Add the reaction components together in order listed above. Mix gently and spin.
  5. Incubate at reaction temperature for 3 hr to overnight.
