Because it didn’t come out vector PCR(gel electrophoresis), 
we operated re-experiment to change template and template amounts.
Using template 1. Biobrick 2010 1-3A(pSB1C3) 2. Biobrick 2010 pSB1C3 3. Biobrick 2010 2-9A(pSB1A3) 4. control

Biobrick 2010 2-9A(pSB1A3) -> Gel extraction Gel Electrophoresis

Biobrick 2010 2-9A(pSB1A3), Biobrick 2010 1-3A(pSB1C3), Biobrick 2010 pSB1C3, Biobrick 2010 2-9A(pSB1A3)
As a result, it didn’t come out band of 1-3A and pSB1C3. 
We concluded re-experiment from liquid incubation to mini-prep. Must check gel electrophoresis band after mini-prep.

Transformation

Using cell strain : BL21(DE3) 50uL
Using plasmid
 L1 : Pet-LuxR-PT7/cI(OR2)-GFP   5uL
 L2 : Pet-LuxR-PT7/cI(OR1)-GFP   5uL
 L3 : Prom-LuxR-PT7/cI(OR2)-GFP 5uL
 L4 : Prom-LuxR-PT7/cI(OR1)-GFP 5uL

After transformation

We added IPTG(0μM / 100μM / 200μM) to each cell strain. It became 12 plates.
※A Reason of using DE3 cell strain
DE3 cell strain has T7 RNA Polymerase gene in genome, and under IPTG derivation T7RNAP is expressed.
Plasmid1 has  T7/cI hybrid promoter. 
So if this promoter is accelerated by T7RNAP, GFP is expressed and shines green. 
In other words, we used DE3 cell strain to check T7 accelerating function of PT7/cI.
