- 1 μL T4 DNA Ligase buffer
- 8 μL Oligo’s (FW and REV seperate reactions)
100x diluted oligo’s (1 μM)
- Procedure
- 30 min 37 °C
- 20 min 65 °C
<u.>Annealing
- Mix
- 8 μL FW Phosphorylation mix
- 8 μL REV Phosphorylation mix
- 4 μL 10 mM NaCl low?
- 20 μL MilliQ
- Procedure
- Put reactions in (close to) boiling water
- Let it cool down naturally to ~35 °C
Restriction vector
- Mix
- 1 μL EcoRI
- 1 μL XbaI
- 2 μL Fast digest buffer (10x)
- 8 μL Vector DNA
- 8 μL MilliQ
- Procedure
- 37 °C, 30 min. incubation
- Heat inactivation EcoRI and XbaI
5 min. 80 °C
15 min. 65 °C
Ligation of Metal sensitive promoters in vector
- Mix
- 2 μL T4 Ligase Buffer
- 0.5 μL T4 Ligase
- 1 μL Restriction product (unpurified)
- 1 μL Annealed oligo’s
- 18 μL MilliQ
- Procedure
- Incubation 16 °C, 1 hour
- Heat inactivation Ligase
65 °C, 10 min.
- Jolanda's ligation mix was transformed
- Metal sensitive promotors were ligated
- -RBS according to paul
- +RBS & -RBS according to my annealing and Paul's restriction ligation
