Fermentas FastDigest Protocol

  1. Mix:
    • 2 µL 10X Buffer
    • up to 200 ng DNA
    • 0.5 µL of each enzyme you want to use
    • Water up to 20 µL
  2. Incubate at 37°C in a waterbath for 5-30 minutes (slightly longer if using an air incubator)
  3. Purify digested insert using gel extraction or PCR product purification kit

Digestion of PCR product

  1. Mix:
    • All of PCR product DNA (~28 µL if PCR purification was eluted in 30 µL)
    • 3.5 µL 10x BSA
    • 3.5 µL 10x buffer (see NEB website for optimal double digest buffer choices)
    • 0.2 µL enzyme 1 (20 units/µL)
    • 0.2 µL enzyme 2 (20 units/µL)
    • distilled water to 35 µL total volume
    • Note: keep the glycerol concentration below 5%, the volume of both restriction enzymes added should not exceed 5% of the total reaction volume.
  2. Incubate at least an hour (better overnight) at 37 °C.
  3. Purify digested insert using PCR product purification kit.

Digestion of BioBrick vector: Recommended Procedure

  1. Mix:
    • 700 ng BioBrick vector (BBa_V0002 or BBa_V0100)
    • 1 µL 10 x BSA
    • 1 µL 10x buffer (see NEB website for optimal double digest buffer choices)
    • 0.2 µL enzyme 1 (20 units/µL)
    • 0.2 µL enzyme 2 (20 units/µL)
    • distilled water to 10 µL total volume
    • Note: To keep the glycerol concentration below 5%, the volume of both restriction enzymes added should not exceed 10% of the total reaction volume.
  2. Incubate overnight at 37 °C.
  3. The next morning, add 0.1 µL CIP (10 units/µL) and incubate for 1 hr. at 37 °C.

BioCoder version

Following is the Silver:Restriction digest protocol in BioCoder, a high-level programming language for expressing biology protocols. What you see here is the auto-generated text ouput of the protocol that was coded up in BioCoder (see Source code). More information about BioCoder can be found on my home page.
