Microscopic DAP complementation experiment
We used wild type E.coli transformed by part J23107 (RFP) and dapA- E.coli (w121) auxotroph to DAP. E.coli transformed by part J23107 (RFP) is able to synthesize DAP and export it. We suppose dap- E.coli could be feed by wt E.coli.
We tried to observe kinetics by fluorescence microscopy. We let separately in culture overnight dapA- E.coli (LB/erythromycine/DAP) and rfp wt E.coli (LB ampicillin). The day after, we diluted both liquid culture 1/200 to have exponential culture.
Then we put on slide different conditions:
- 50% wt rfp / 50% dapA- (colomn 1)
- 70% wt rfp / 30% dapA- (colomn 2)
- 30% wt rfp / 70% dapA- (colomn 3)
- 90% wt rfp / 10% dapA- (colomn 4)
- 10% wt rfp / 90% dapA- (colomn 5)
