Use Roche's Rapid DNA Ligation Kit, stored at -20 °C.
Keep the total mass of DNA below 200 ng.

  1. Mix:
    • 50-100 ng de-phosphorylated, digested BioBrick vector (~2 µL, ~18 pmol vector).
    • 4-10x molar excess digested insert DNA.
    • 2 µL tube #2 (DNA dilution buffer)
    • distilled water to final volume of 10 µL total volume
  2. Add 10 µL of freshly mixed tube #1 (T4 DNA ligase buffer).
  3. Add 1 µL tube #3 (T4 DNA ligase).
  4. Mix well, incubate for 15 min. at room temperature.
  5. Proceed to transformation. Store excess ligation mixture at -20 °C.
