Applications of BBa_K5097004

Experience

We tested the expression of BFP under control of PREmR34. To do this, we generated this reporter construct. We used this to transform E. coli DH5alpha cells, and then grew the cells in LB supplemented with buffering agents to achieve the desired pH. In parallel, we measured the OD595 of the culture and its fluorescence (Ex. 555 nm, Em. 596 nm). We then normalized the absorbance to cell density and calculated the change in this normalized value over the course of the experiment.

Figure 1: Expression of BFP under the control of PREmR34 in media with different pH. The pH indicated was created by adding a buffering agent to LB to adjust the pH. UB, unbuffered LB.

From these results we concluded that the PREmR34 riboswitch deos display pH sensitive induction of BFP, with expression maximally at pH 8.5, consistent with the activity reported of the Alx riboswitch.
