=='''Dear Journal! :)'''==
Here you will find the overall progression of our work at the laboratory designing Chimi.

The first thing we did was to extract the plasmids from the iGEM plaque.
- From the 2013 kit, Plate 1, Well 19 – o
- From the 2013 kit, Plate 1, Well 2 – i
- From the 2013 kit, Plate 3, Well 17 – c
- 20 µ of miliQ water (ultra pure). Find the plate and stick the tip with water into the well, perforating the aluminum.
- Resuspend the well’s content by gentle pipetting.
- When the water has a dark red color, transfer it to a PCR eppendorf and put on ice.
We performed miniprep procedures with the GenElute HP Plasmid Miniprep kit.
This are the overall steps:
- Harvest cells.
- Resuspend cells.
- Cell lysis.
- Neutralization. Spin method:
- Prepare column.
- Load cleared lysate.
- Wash column with wash solution 1.
- Was column with wash solution 2.
- Centrifuge.
- Elute DNA.
- 5 mL of overnight culture of S. cerevisiae (in BHI medium) were centrifuged at 8500 rpm for 5 min. Discard de supernatant.
- 500 µL of Harja lysis buffer were added to each tube.
- Place 2 min at -20 °C, 1 min in water bath at 90 °C and repeat.
- Vortex 30 s.
- Add 500 µL of chloroform, vortex 2 min and centrifuge 3 min at 8500 rpm.
- Transfer the upper aqueous phase to a tube with 800 µL of chilled 100% ethanol and mix by inversion.
- Incubate for 5 min at room temperature or at 30 °C.
- Centrifuge for 5 min, 8500 rpm, and discard supernatant.
- Wash the pellet with 500 µL of ethanol (100%) by vortex. Repeat step 9.
- Dry pellets at room temperature or at 60 °C.
- Resuspend in 40 µL miliQ water.
- Competent yeast were made following the procedure mentioned before.
- PCR using primers 6 & 1 (A) and 34 & 9 (B) was run to extract VP16 from the Nal1 plasmid and GCR.
- Confirmation gel (2013-06-26 19 hr 16 min.jpg & 2013-06-26 19hr 15 min.jpg) with wells:
- Ladder
- PCR A
- PCR B
- Miniprep for Nal. 1
