Lab work

A - Aerobic/Anaerobic regulation system

Objective : characterize BBa_K1155000, BBa_K1155004, BBa_K1155005, BBa_K1155006

1 - Tranduction of Km in MG1655Z1

Abdou, Anaïs, Damir, Nadia, XiaoJing

We observed lysis areas in the strain MG1655Z1 Δfnr::Km after transduction. We will continue the transduction protocol.

Picture: lysed cells comparison.

0µl phage(control): the petri dish is cloudy, bacteria are not lysed.
50µl phage: the petri dish is clear, bacteria are lysed by phages.

Objective : obtaining BBa_K1155007

1 - Extraction of BBa_K115007 from DH5αstrain

Abdou

Protocol : High-copy plamid extraction

We extracted plamid from colonies number 10, 14 and 15.

Nanodrop

BBa_K1155007 in clone 10 : 38ng/µl
BBa_K1155007 in clone 14 : 48.5ng/µl
BBa_K1155007 in clone 15 : 52 ng/µl

The extraction was good. We will sequence our plasmids.

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

Objective : Obtaining FNR and BphR2 proteins

1 - Electrophoresis of the PCR of BphR2 Part I, BphR2 Part II, RBS_BphR2 Part I, FNR Part I, FNR Part II, RBS_FNR Part I to check the gel purification

Well 1 : 6µL DNA Ladder
Well 2 : 5µL of BphR2 Part I + 1µl of 6X loading dye
Well 3 : 5µL of BphR2 Part II + 1µl of 6X loading dye
Well 4 : 5µL of RBS-BphR2 Part I + 1µl of 6X loading dye
Well 5 : 5µL of FNR Part I + 1µl of 6X loading dye
Well 6 : 5µL of FRN Part II + 1µl of 6X loading dye
Well 7: 5µL of RBS-FNR Part I + 1µl of 6X loading dye
Gel : 0.8%

Expected size :

BphR2 Part I : 178 bp
BphR2 Part II : 790bp
RBS-BphR2 Part I : 197bp
FNR Part I : 597 bp
FNR Part II : 200bp
RBS-FNR PartI : 615bp

We lost all our PCR fragments. We will do the PCR again.
