Construction
To characterize Plux/tet hybrid promoter (BBa_K934024), we constructed Plux/tet-GFP (BBa_K934025) by ligating the Plux/tet hybrid promoter (BBa_K934024) to the upstream of promoterless GFP generator (BBa_I13504).
pSB3K3-PlacIq-LuxR-Ptrc-TetR / pSB6A1-Pluxtet-GFP (JM2.300)…Sample
pSB3K3-PlacIq-LuxR-Ptrc-TetR / pSB6A1-⊿P-GFP (JM2.300)…negative control
pSB3K3-PlacIq-LuxR-Ptrc-TetR / pSB6A1-Plac-GFP (JM2.300)…positive control
2.Strain
JM2.300
3.Protocol
1.1 Prepare overnight culture of reporter cell at 37 ℃ for 12hours.
1.2 Take 30 μl of the overnight culture of reporter cells into LB (3 ml) + antibiotics (Amp 50 μg/ml + Kan 30 μg/ml). (→fresh culture)
1.3 Dilute the flesh culture in 1:50 by the following conditions:
A) LB
B) LB + aTc (500 ng/ ml)
C) LB + 3OC6HSL (1 μM )
D) LB + aTc (500 ng/ml) + 3OC6HSL (1 μM )
1.4 Incubate the fresh culture of diluted inducer cell for 2 hours.
1.5 Flow cytometer measurements for GFP expression of reporter cell.
