Experiments
Gibson Assembly
1.Set up the following reaction on ice:
2-3 Fragment Assembly | 4-6 Fragment Assembly | Positive Control** | |
---|---|---|---|
Total Amount of Fragments | 0.02–0.5 pmols* X μl | 0.2–1 pmols* X μl | 10 μl |
Gibson Assembly Master Mix (2X) | 10 μl | 10 μl | 10 μl |
Deionized H2O | 10-X μl | 10-X μl | 0 |
Total Volume | 20 μl*** | 20 μl*** | 20 μl |
* Optimized cloning efficiency is 50–100 ng of vectors with 2–3 fold of excess inserts. Use 5 times more of inserts if size is less than 200 bps. Total volume of unpurified PCR fragments in Gibson Assembly reaction should not exceed 20%. ** Control reagents are provided for 5 experiments. *** If greater numbers of fragments are assembled, additional Gibson Assembly Master Mix may be required.
2.Incubate samples in a thermocycler at 50°C for 15 minutes when 2 or 3 fragments are being assembled or 60 minutes when 4-6 fragments are being assembled. Following incubation, store samples on ice or at -20°C for subsequent transformation.
