--> Pipette 5.5 μL master mix into each PCR tube
--> Add 1.0 μL insert into each tube
--> Add 100 ng vector DNA
--> Add x μL dH2O = 13.5 - vector volume
--> Mix by flicking
LabNet OptiMax Thermocycler: BbsI Dig/Lig
- 6x [37°C, 5 min; 23°C, 5 min]
- 4°C, ∞
Transformation(s)
- Thaw 2 tubes chem competent DH5α-turbo on ice
- Transfer 10.0 μL each ligation (1/2 rxn.) to fresh sterile 0.5 mL tube
- Add 50 μL DH5α-turbo; pipette up-and-down 3x GENTLY
- Incubate 5 min. on ice
- Plate on 100 μg/mL amp
RESULTS (5/08/15)
- ~25 colonies on each ligation plate, and same number on negative controls
- Rene has observed something similar for dig/lig.
- Pick grow up liquid cultures for two colonies from each plate on Monday
