A - Aerobic/Anaerobic regulation system
Objective : characterize Bba_K1155000, Bba_K1155004, Bba_K1155005, Bba_K1155006
1 - Gel purification of the digestion of Bba_K1155004, Bba_K1155005, Bba_K1155006 by SpeI

Protocol : [http://www.mn-net.com/tabid/1452/default.aspx Gel purification ]
Nanodrop :
- NarG : 10.5ng/µL
- NarK : 16.8ng/µL
- NirB : 24.3
We lost our plasmids. We will do the digestion again. |
2 - Extraction of Bba_K1155000, Bba_K1155004, Bba_K1155005, Bba_K1155006 from DH5α

- Nir B :65.8ng/µL
- Pfnr : 227ng/µL
The extraction was good. We will digest Bba_K1155000, Bba_K1155004, Bba_K1155005, Bba_K1155006. |
3 - Digestion of Bba_K1155004,Bba_K1155005, Bba_K1155006 by EcoRI/SpeI

- EcoRI FD : 1µL
We let the digestion at 37°C during 15 minutes.
4 - Electrophoresis to check the digestion of Bba_K1155004,Bba_K1155005, Bba_K1155006 by EcoRI/SpeI
Anaïs, Nadia
Expected sizes :
- PSB1C3 : 2070kb
- NarK, NarG, NirB : 200kb
We obtained NarK, NarG, NirB fragments at the right size but in very few quantity. We do it again but this time we will use more quantity of enzymes. |
5 - Digestion of Bba_K1155000, Bba_K1155004,Bba_K1155005, Bba_K1155006 by SpeI and EcoRI/SpeI
Anaïs, Nadia
- Digestion by SpeI :
- Buffer : 2µL
- SpeI : 2µL
- ADN : 15µL
- H20 : 1µL
- Digestion by EcoRI and SpeI :
- Buffer : 3µL
- SpeI : 2µL
- EcoRI : 2µL
- ADN : 20µL
- H20 : 3µL
We let digestions at 37°C during 10 minutes ??????
6 - Electrophoresis to check the digestion of Bba_K1155000, Bba_K1155004,Bba_K1155005, Bba_K1155006 by SpeI and EcoRI/SpeI
Anaïs, Nadia
Expected sizes :
- Pfnr in PSB1C3 : ...
- Nar K in PSB1C3, NarG in PSB1C3, NirB in PSB1C3 : ...
- PSB1C3 : 2070kb
- NarK, NarG, NirB : 200kb
- Pfnr : ...
Well 1 : we have done one digestion so we have to obtain one fragment, we have two stripes, the digestion of Bba_K1155000 by SpeI wasn't good. Well 2, 3, 4, 6, 7 : we obtain NarG, NarK and NirB in PSB1C3 and Pfnr, NarK fragments at the right size, we can purify it. Well 8, 9 : we have done two digestions so we have to obtain two fragments, we have only one stripe, the digestion of Bba_K1155005 and Bba_K1155004 by EcoRI/SpeI wasn't good. |
7 - Gel purification of the digestion of Bba_K1155000 and Bba_K1155006 by EcoRI/SpeI and Bba_K1155004, Bba_K1155005 and Bba_K1155006 by SpeI

Nanodrop :
- RSB-LacZ-Term : 59.6ng/µL
- RBS-AmilCP-Term : 28.7ng/µL
WE obtain few quantities of plasmid that's why we will make an Ethanol precipitation to concentrated it. |

Expected sizes :
- BphR2 Part I : 178kb
On the first gel, all deposits disappear so we did the electrophoresis again. On the second gel, we didn't obtain stripes at the good size. We do the PCR again using new quantities and a new PCR program. |
