Ligation
Procedures
Set up the ligation mix according:
| Reagents | 1:3(μl) | 1:5(μl) | Vector(μl) |
|---|---|---|---|
| Vector | 1 | 1 | 1 |
| Insert | 3 | 5 | N/A |
| 10X BUFFER | 1 | 1 | 1 |
| T4 Ligase | 1 | 1 | 1 |
| H2O | 4 | 2 | 7 |
| Total Volume | 10.0 | 10.0 | 10.0 |
For sticky end ligation, incubate the tube containing above mentioned chemicals on the bench for a period of 3-4 hours or overnight.
Important point to note is that 1:3 dilution means that during ligation, for 1 unit of vector, there are 3 units of insert and in 1:5 ligation, for 1 unit of vector there is 5 units of insert.
Notes
- For standard ligation, 100-200 ng of vector DNA is required and this can be checked using nanodrop protocol (refer to Nanodrop Spectrophotometer protocol).
- Ligation calculation can be used to calculate the amount of vector and insert required for the ligation but 1:3 or 1:5 ligation ratios are used more frequently.
