Lab work
A - Aerobic/Anaerobic regulation system
Objective : characterize BBa_K1155000 and BBa_K1155004, BBa_K1155005, BBa_K1155006
1 - Purification of colonies: NirB with RBS-LacZ-Term in pSB1C3, Pfnr with RBS-AmilCP-Term in pSB1C3 by streaking colonies in aerobic or anaerobic conditions
XiaoJing
Purification of 08/28/13 didn't work. We have blue colonies for Pndh* with RBS-AmilCP-Term in pSB1C3 in aerobic and anaerobic conditions. We also have blue colonies for NirB with RBS-LacZ-Term in pSB1C3 in anaerobic conditions. We will streak these colonies again. |
We streak colonies from construction :
- Pndh* with RBS-Amil CP-Term in pSB1C3 with O2 at 37°C
- Pndh* with RBS-Amil CP-Term in pSB1C3 without O2 at 37°C
- Pndh* with RBS-Amil CP-Term in pSB1C3 with O2 at 30°C
- Pndh* with RBS-Amil CP-Term in pSB1C3 without O2 at 30°C
- NirB with RBS-LacZ-Term in pSB1C3 with O2 with Xgal at 37°C
- NirB with RBS-LacZ-Term in pSB1C3 without O2 with Xgal at 37°C
