Table 3 Crosstalk matrix for the promoter prhl ([http://parts.igem.org/Part:BBa_I14017:Experience BBa_I14017])
In this set of experiments the promoter pRhl (ref) was tested for potential crosstalk. In the top left position we observe the induction of pRhl (ref)by C4-HSL bound to the regulator RhlR(ref). The switching behaviour was observed at a C4-HSL concentration of 1 μM.

In the case of 3OC12-HSL binding the RhlR (ref)regulator and subsequently the promoter pRhl (ref)insignificant crosstalk has been observed. Severe crosstalk was observed in the case of 3OC6-HSL binding the RhlR (reg)regulator followed by induction of pRhl(reg). The transition occurred at a concentration of the inducer molecule of 1 μM but compared to the reference curve a lower value of fluorescence per OD was observed (1000 a.u.). Another case of crosstalk with the pRhl (ref) was detected with 3OC12-HSL binding to the corresponding LasR (ref)regulator followed by inducing the promoter pRhl(ref). Here switching occurred at a concentration 1 nM of 3OC12-HSL and reached fluorescence per OD of 750 a.u.. This is approximately 0.5 fold the value of the fluorescence per OD shown by the reference curve indicated in green.
