Expression level check on two different promoters + plasmid sets

Purpose:

To measure and compare the activities of two different promoters + plasmid sets by fluorescence of GFP downstream of each promoter. Lambda cI-regulated promoter and the lux lac hybrid promoter were tested.

Samples:

・A4Δp pc1-GFP
・A4 hybrid GFP PBR322TetR (+)AHL
・A4 hybrid GFP PBR322TetR (-)AHL
*The promoter pcI sequence was designed to contain OR1, -35, and -10 regions, but not R2 or OR3.

Procedure:

AHL assay Standard protocol
Wash
OD and fluorescence were measured 0, 3, and 6 hours after the fresh culture incubation started.

Result & Conclusion:

Two plasmid sets, A4Δp+pc1-GFP and A4 hybrid+GFP PBR322TetR (+)AHL, shows almost the same fluorescence of GFP, indicating that expression levels of both sets are almost the same though the latter is a bit smaller. Parameter set.jpg
