To test this promoter we performed two different assays. First of all we cloned this promoter in pSB1C3 and then we inserted downstream the GFP BBa_I13504. In the same plasmid we cloned J23100-CymR-B0015 in order to repress the promoter. To test this system we used different concentrations of cumate which binds CymR preventing its repression, thus allowing the GFP expression.

In liquid assay:
We inoculated a 20ml culture. After overnight growth, we diluted the culture to OD600 = 0.2. Then we aliquoted 200 μl in 8 replicates in a microtiter plate at different concentrations of cumate. The reading was performed in a monochromator at 485-510nm.
In the plate assay:
We streaked the culture on LB Agar plates containing different p-cumate concentrations.
