Purpose 1:
To check if LacI hybrid promoter is activated by AHL and repressed by LacI.
Purpose 2:
To obtain parameters of LacI hybrid promoter for computational simulation.
Samples:
1. pTrc99A + [LacI hybrid promoter – GFP] (LacI+)
2. pBR322 TetR + [LacI hybrid promoter – GFP] (lacI-)
3. pTrc99A + [placQI – GFP] (placQI is constitutive promoter)
4. pTrc99A + [LacI promoter – GFP]
5. pBR322 TetR + [LacI promoter – GFP]
Repressor LacI expression:
pTrc99A expresses LacI
pBR322 TetR does NOT express LacI
Antibiotics resistance:
pTrc99A gives ampicillin-resistance
pBR322 TetR gives ampicillin-resistance
[LacI hybrid promoter – GFP] gives kanamicin-resistance
[placQI – GFP] gives kanamicin-resistance
