Applications of BBa_K911001
BBa_K911001 has been inserted into the following construct:
The sequence of this construct has been verified.
In order to test it, we transformed the construct into e.coli and attempted to induce GFP expression with both increasing magnesium concentrations and increasing IPTG concentrations. The cells were then interrogated at the correct GFP absorbtion and emission wavelengths (450nm and 545nm respectively) in a plate reader.
The results of this assay are shown below.
As can be seen, the assay did not give the expected results. At differing IPTG concentrations, the response to magnesium seems to have inverted.
We repeated this experiment, using a different range of magnesium concentrations (1μM - 5mM) and doing duplicates in alternate rows. The cells grew well, although they did not appear to do so in an exponential fashion.
The construct was then transformed into Bacillus subtilis, with a view to repeat the same assay in this new chassis. Because the part originally comes from bacillus, we hoped that this might give more useful data. Unfortunately, we did not have time to characterise the part in this chassis, as our transformation attempts failed.
