Parts Data
Description:
We
assembled BBa_E0840
under the pLas promoter BBa_R0079
that was contained into K574009. We kept pSB1A2 as the scaffold
vector.
Methods:
1.
Ligate BBa_E0840
downstream of BBa_K574009,
which acts as a reporter.
2. Culture the positive colony at 37°C,
220 rpm for 12 hours, as well as the DH5alpha.
3. Dilute 1:25 the
former in 12 falcon tubes (4 ml cultures), each 3 tubes as a group.
The later is also diluted in 3 tubes as the negative control.
4.
After culturing for another 2 hours, as their OD600 reach 0.2, induce
with 3OC12HSL 0, 1e-6 M, 1e-5 M and 1e-4 M respectively.
5. Take
samples after 1 hour, 4 hours, 8 hours and 24 hours, that is,
centrifugalizate 0.5 mL of each culture and suspend them by 1 mL of
PBS (phosphate-buffered saline).
6. Measure the fluorescence of
the samples with the flow cytometer.
Results:
From the chart, we can see that cells were hardly induced in the control group, and with the concentration of inducer growing, the intensity of GFP increased by groups. The most efficient concentration of inducer was around 10^-6M, and to most groups, the intensity of GFP reached its maxium after 4 hours.
