Choose a protocol to read its description :
- Competent cells
- Transformation
- DNA extraction
- Digestion
- Ligation
- Measure of temperature and shaking speed influence
- Measure of osmotic pressure influence
- Granules extraction and intein cleavage
- Biofilms quantification
- Extra
Ligation
- 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
If it follows a digestion without purification: 20 minutes of thermoinactivation at 70°C
Incubate 3h or overnight at room temperature or at 15°C
