Lab work
A - Aerobic/Anaerobic regulation system
Obtaining the NarK or NarG or NirB _RBS-LacZ-term in PSB1C3
1 - Gel electrophoresis to check the digestion of Bba_K1155004,Bba_K1155005, Bba_K1155006 by EcoRI and SpeI

Expected sizes :
- PSB1C33 : 2070kb
- NarK, NarG, NirB : 200kb
We obtained fragments of the right size but in very few quantity. We do it again but this time we will use more quantity of enzymes.
2 - Digestion of Bba_K1155004,Bba_K1155005, Bba_K1155006 by EcoRI and SpeI
2.1 - Migration of the remaining 45µL of BBa_J004450 digested by EcoRI/Pst1

Now we can do a gel purification of the highest band which contains the PSB3K3 plasmid.
2.2 - Electroelution of the highest band to extract the PSB3K3 plasmid from the gel
Nadia
Protocol : Electroelution
We let the plasmid precipitate during the night.
Obtaining RBS_LacZ+Term_PSB1C3
1 - Colony PCR on e.coli with RBS_LacZ+Term_PSB1C3 for 25 colonies
Anaïs
- Colony counting :
- Low concentration petri dish : 47 colonies
- High concentration petri dish : 145 colonies
- Picking of 25 colonies
- Preparation of 700µL of Master mix
- H2O : 590µL
- dNTP : 28µL
- VF2 primer : 3.5µL
- VR primer : 3.5µL
- DreamTaq buffer 10x : 70µL
- DreamTaq enzyme : 5µL
Protocol : Colony PCR
PCR Program :
2 - Gel electrophoresis of the colony PCR products

Expected size : 3583bp
Colonies 10, 14, 15 exhibit plasmids with the right length.
3 - PCR product (made the 08/01/2013) purification
Damir
available quantity:
- FNR Part1 : 10 µl
- FNR Part2 : 19 µl
- RBS FNR Part1 :16.1µl
- RBS BphR2 Part1 : 28µl
- BphR2 Part1 : 16.4 µl
- BphR2 Part2 : 18.9 µl
Protocol : kit purification
Manipulation error : The elution step was made using the recuperation tube from the filtering step, instead of a new, clean eppendorf tube.
