Protocols


Choose a protocol to read its description :

  1. Competent cells
  2. Transformation
  3. DNA extraction
  4. Digestion
  5. Ligation
  6. Measure of temperature and shaking speed influence
  7. Measure of osmotic pressure influence
  8. Granules extraction and intein cleavage
  9. Biofilms quantification
  10. Extra






    Ligation



      If it follows a digestion without purification: 20 minutes of thermoinactivation at 70°C

    • Add x µL DNA (the entire digestion gel purification for part ligation) Plasmid: 50 to 200 ng; Insert: 100 ng (0,5 kb) to 1 µg (10 kb))
    • Add 2 µL Buffer T4 DNA ligase (Attention: this buffer contains ATP, defrost on ice)
    • Add 0,5 µL T4 DNA ligase (0,5 U) --> Add the enzyme last
    • Add sterile water qs 20 µL

    • Incubate 3h or overnight at room temperature or at 15°C
