Construction of pFlhB - mRFP Tripart (LVA+)

Aim : Construction of "pFlhB-RBS-mRFP-dbl ter" (pFlhB-I732078) Part icon regulatory.pngPart icon rbs.pngIcon reporter.pngPart icon terminator.pngPart icon terminator.png
We can only do the construction with mRFP Tripart (LVA+) because the stable strain with the Biobricks I732011 (mRFP Tripart LVA-) don't to growth.
