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:
Raphaël
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:

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 !)
