Transformation of TOP10 chemically competent E.coli with the overnight ligations from 07/22. Recuperation for 30 mins after the heat shock in SOC, then plating with 150µl of the transformmation on the ampicilin plate, incubation overnight at 37°C.

Gel purification with the Quiagen kit.
All bands are eluted with 30μL of water.

DNA purification from the 07/23 minipreps using the PCR purification kit.
Elution with 30µl water. In the result we have 2x28µl of each biobrick that will serve us as a vector for the ligation:

Minipreps : 4 minipreps of a 5ml culture per biobrick, eluted with 30μL buffer and collected into 1 tube for a total volume of around 120μL:
- attC
- term/attC/mRFP
- attC-term/attC/mRFP (colony from the transformation plate of 07/21)
- pLux-RBS/GFP/term (colony from the transformation plate of 07/21)
Nanodrop to determine the amount of DNA in the miniprep samples and after gel purification and PCR purification:
| Sample name | 260/280 | 260/230 | ng/μL
|
| attC(miniprep) | 1.85 | 2.09 | 66.6
|
| t-attC-mRFP (miniprep) | 1.85 | 2.17 | 78.3
|
| pLux-GFP (miniprep) | 1.86 | 2.38 | 174.8
|
| attC-t-attC-mRFP (miniprep) | 1.83 | 2.28 | 75.9
|
| attC (PCR purif.) | 1.70 | 1.32 | 20.0
|
| pLux (PCR purif.) | 1.79 | 1.88 | 70.3
|
| LuxI (gel purif.) | 1.71 | 0.05 | 5.1
|
| LacZ (gel purif.) | 2.26 | 0.02 | 3.1
|
| TetA(C) (gel purif.) | 1.92 | 0.08 | 10.8
|
| GFP (gel purif.) | 1.80 | 0.08 | 6.2
|
| t-attC-mRFP (gel purif.) | 1.40 | 0.01 | 1.6
|
| LuxR (gel purif.) | 1.66 | 0.06 | 3.4
|
Obviously, there is not enough DNA after gel purification to do a ligation...
Overnight culture
2x20mL per biobrick, the goal is to do minipreps on 10mL of pellet tomorrow (increase the initial amount of DNA >> increase the amount of DNA after gel purification !)
