Ligation
After following our digestion protocol a ligation can be performed.
Different ratios of vector:insert are used, to get the best result out of the ligation.
To check for self-closing vectors a vector-only sample will be ligated.
Materials
- PCR tubes/PCR plate
- vector and insert DNA
- dH20
- T4 DNA ligase
- T4 DNA ligase buffer
Note: All materials should be held on ice during preparation.
