ZYMO purification
1. Add PCR products(50㎕) and DNA binding buffer(200㎕) into 1.5mL tube(Commonly adding DNA binding buffer for double amount of PCR products, but it must be 200㎕ at least). After that, mix this tube for a second with vortex and move to 2mL tube with column. After operating centrifuge, transfer remaining a little PCR product to 2mL tube with column.
2. centrifuge 1min → throwing away left solution
3. Same to mini-prep
* wash buffer 200㎕ -> centrifuge 30sec -> throwing away left solution. X2
* wash buffer 200㎕ -> centrifuge 1min -> throwing away left solution. X1

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.

To use cell strain : BL21(DE3) 50㎕
To use plasmid

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.
