Ligation Reaction
Materials:
- MQ water
- 1.5 ml tubes
- 10x T4 Ligation buffer
- T4 Ligase
- Insert
- Vector
Reaction mixture:
Component | 20 µl | Final concentration |
---|---|---|
MilliQ water | up to 20 µl | |
10 ligation buffer | 2 µl | 1x |
Vector | x µl | 20-100 ng |
Insert | x µl | 3:1 molar ratio over vector* |
T4 DNA ligase 5 U/µl | 2 µl | 0.5 U/µl |
* When restricted PCR products are ligated together, a 1:1 molar ratio is used.
All the reagents are added following the order listed in the table above [1].
After finishing the reaction mixture, the content is mixed and incubated at room temperature (~22°C) for 20 min.
