Ligation Mix
- Example - 10ul mix
- 1.0 [math]\displaystyle{ \mu }[/math]L 10X T4 ligase buffer
- 0.5 [math]\displaystyle{ \mu }[/math]L T4 Ligase
- 6:1 Molar ratio of insert to vector ([math]\displaystyle{ \sim }[/math]10ng vector)
- X[math]\displaystyle{ \mu }[/math]L dd[math]\displaystyle{ \rm{H_2O} }[/math] to bring the total to 10[math]\displaystyle{ \mu }[/math]L
Calculating Insert and Vector Amounts
Insert Mass =[math]\displaystyle{ 6\times\left[\frac{\rm{Insert\ Length}}{\rm{Vector\ Length}}\right]\times \rm{Vector\ Mass} }[/math]
Reaction Conditions
- Let the 10 [math]\displaystyle{ \mu }[/math]L solution sit at [math]\displaystyle{ 22.5^o }[/math]C for 30min
- Denature the ligase at [math]\displaystyle{ 65^o }[/math]C for 10min
- Dialyze for 20 minutes if electroporating
- Use disks shiny side up
- Store at -20C
