PCRBecause it didn’t come out vector PCR(gel electrophoresis), we operated re-experiment to change template and template amounts.

Biobrick 2010 2-9A(pSB1A3) -> Gel extraction Gel ElectrophoresisBiobrick 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.
FASTR Cloning (Plasmid1)
Vector (about 2kbp) -pSB1A3 (conservative solution 100ng/㎕)
Insert (about 1kbp) 1. Pet-LuxR-PT7/cI(OR2)-GFP (conservative solution 25ng/㎕) 2. Pet-LuxR-PT7/cI(OR1)-GFP (conservative solution 25ng/㎕) 3. Prom-LuxR-PT7/cI(OR2)-GFP (conservative solution 25ng/㎕) 4. Prom-LuxR-PT7/cI(OR1)-GFP (conservative solution 25ng/㎕)

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

From yesterday, we did mini-prep liquid incubated sample 1-3A and pSB1C3. And then it is eluted by 50㎕ Elution Solution. ↓ Gel Electrophoresis(1㎕)L1 : Pet-LuxR-PT7/cI(OR2)-GFP 5㎕ L2 : Pet-LuxR-PT7/cI(OR1)-GFP 5㎕ L3 : Prom-LuxR-PT7/cI(OR2)-GFP 5㎕ L4 : Prom-LuxR-PT7/cI(OR1)-GFP 5㎕ Remaining of above sample is transformed and incubated. cell strain : XL10G(50㎕/tube) plasmid : L1~L4(total 4)
