J23101-B0032-TetR-B1006- phlFp -GFP

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

Results

The fold change between construct A (pSB3K3-BBa_phlFp -E0240) and negative control (pSB3K3-BBa_E0240), and that of construct D (pSB3K3-BBa_J23101-B0032-C0040-B1006- phlFp-E0240) is around 13.2 times and 7.01 times respectively.

We hypothesized that this may 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 OD600 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.

Characterization was done using E. coli strain JW0336. Cells were first precultured overnight and were subcultured to mid-log phase where GFP emission measurements were made using an EnVision® multilabel reader. This result was obtained by combining 3 characterization data obtained in 3 different days. Error bar present SD from 3 biological replicates.
