J23101-B0032-TetR-B1006- phlFp -GFP

This part is constructed for investigating the effect of tetR over phlFp.

Results

The fold change between pSB3K3-phlFp - BBa_E0240(A), negative control (pSB3K3-BBa_E0240) and that of pSB3K3-BBa_J23101-B0032-C0040-B1006- phlFp -E0240(D) is around 13.2 times and 7.01 times respectively. Mean and standard error mean (SEM) are calculated and represented by the height of the bar and the error bar respectively.

This is due to the toxicity of BBa_C0040 (tetR). The toxicity reduces the growth rate of the E. coli containing this plasmid. The strong promoter BBa_J23101 makes this effect more significant when doing the characterisation. Though all the data were collected with OD within the mid-log range, there is still a variation between them, making a significant difference in the RFU. It is ungrounded to say tetR interferes the functionality of phlFp at this stage.
