The ligation reaction was transformed with DH5α-turbo cells and plated for overnight growth. The Ampicillin plate produced 11 colonies of AubR, of which 2 were picked for further growth in liquid cultures. After mini-prepping the liquid cultures, a gel verification was performed. The two expected bands for the AubR-MRV vector complex should be around 3200bp and 860bp. The gel shown below indicates that the ligation was successful. | The ligation reaction was transformed with DH5α-turbo cells and plated for overnight growth.

Design Notes
Here is the inducible promoter sequence:
Stage 1-Insert Regulator ORFs
Phusion PCR
The AubR part was first synthesized by Ryan Muller in Spring of 2015. Stage 1 consisted of the insertion of the open reading frame into a cloning vector found here. The following reaction was conducted to amplify and fuse AubR with DNA plasmid.
Reagent | Volume(uL) | Mix(x5) | Thermal Cycler Step | Step Temperature (°C) | Step Length (sec) | Step Repeats |
---|---|---|---|---|---|---|
DNA Plasmid | 1.0 | 5.0 | Initial Denaturation | 98 | 180 | 1x |
10uM F Primer | 1.0 | 5.0 | Denaturation | 98 | 10 | 35x |
10uM R Primer | 1.0 | 5.0 | Annealing | 66 | 30 | 35x |
10mM dNTPs | 1.0 | 5.0 | Elongation | 72 | 60 | 35x |
Phusion Pol. | 0.5 | 2.5 | Elongation | 72 | 600 | 1x |
5x HF buffer | 10 | 50 | Cold Storage | 4 | ∞ | 1x |
dH2O | 36 | 180 | ||||
Total | 50.5 |
Digestion and Ligation
The PCR product and the cloning vector were digested with EcoRI and XbaI. These were gel verified and then combined in a 15uL ligation reaction (10 minutes at 37°C heat block). The reaction mixture is shown below:
Reagent | Reaction Volume(uL) | Negative Ctrl. Volume(uL) |
---|---|---|
Insert DNA | 3.0 | 0.0 |
Vector DNA | 3.5 | 3.5 |
2x Ign Buffer(Roche) | 7.5 | 7.5 |
T4 Ligase(NEB) | 1.0 | 5.0 |
dH2O | 0.0 | 3.0 |
Total | 15 | 15 |
The ligation reaction was transformed with DH5α-turbo cells and plated for overnight growth. The Ampicillin plate produced 11 colonies of AubR, of which 2 were picked for further growth in liquid cultures. After mini-prepping the liquid cultures, a gel verification was performed. The two expected bands for the AubR-MRV vector complex should be around 3200bp and 860bp. The gel shown below indicates that the ligation was successful.
