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.

  • 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
