Clone 10,14 and 15 plamid extraction using nucleospin kit.

Protocol : hight copy plamid extraction

Results: concentration measured by nanodrop

• clone 10: C=38ng/µl 260/280= 1.78
• clone 14: C=48.5ng/µl 260/280=1.90
• clone 15: C=52 ng/µl 260/280=1.78

We still have to sequence plasmids in order to verify our results.

A - Aerobic/Anaerobic regulation system / B - PCB sensing system

1 - Gibson assembly.

August 1st PCR purification to be sure about the experiment. BphR2 part1, BphR2 part2 and RBS_BphR2_part1, FNR part1, FNR part2 and RBS_FNR_part1.

Protocol : PCR_clean_up

Results:

we have no fragment so we must do again these PCRs
