Materials and Methods

Construction

-Strain

All the plasmids were prepared in XL1-Blue strain.

Ⅰ.Adjustment of MazF Expression

-Plasmids

GFP : Pcon-rbs-gfp (pSB6A1), Plac-rbs (pSB3K3)

MazF : PBAD-rbs-mazF-tt-Pcon-rbs-gfp (pSB6A1) , Plac-rbs (pSB3K3)



Assay protocol

Ⅰ.Adjustment of MazF Expression

-Pre-culture 1. Suspend colonies on a master plate into LB medium containing ampicillin (50 microg / mL) and kanamycin (50 microg / mL).

2. Incubate with vigorous shaking for 12 h.

-Incubation and Assay

1. Measure the turbidity of the pre-cultures.

2. Dilute the pre- cultures to 1 / 30 into LB medium containing 4 mL ampicillin and kanamycin.

3. Incubate with vigorous shaking so that the turbidity becomes 0.03.

4. Add arabinose so that the final concentration becomes 0.2%, 0.02%, 0.002% 0.0002% and 0%.

5. Incubate with vigorous shaking for 24 h, and measure the turbidity and the RFU of GFP.
