Cloning Strategy:
 
-
(1) Fragment Preparation:
 
-
SRRz: PCR with primer SRRZ-NcoI-for and SRRZ-rev-in;
 
-
    Purify the product and run PCR with primer SRRZ-NcoI-for and primer SRRZ-BamHI-rev-out;
 
-
 
-
EGFP: PCR with primer EGFP-for-KoZg-for and EGFP-rev-in;
 
-
    Purify the product and run PCR with primer EGFP-for-KoZg-for and primer EGFP-rev-out;
 
-
 
-
PpPhaP: PCR with primer PP-PhaP-NotI-for and PP-PhaP-HindIII-rev;
 
-
 
 
-
LacI(LVA): PCR with primer LacILVA-HindIII-for and LacILVA-rev-in;
 
-
    Purify the product and run PCR with primer LacILVA-HindIII-for and primer LacILVA-rev-PstI-out;
 
-
 
-
CRE(T7ter): PCR with primer CreT7ter—PstI-for and CreT7ter-rev-in
 
-
    Purify the product and run PCR with primer CreT7ter—PstI-for and  CreT7ter-EcoRI-rev-out;
 
-
 
-
PrPhaR: PCR with primer PR-PhaR-NotI-for and PR-PhaR-NdeI-rev;
 
-
 
-
LoxPLacILoxP: PCR with primer LRLacILP-for-in and LRLacILP-rev-in
 
-
    Purify the product and run PCR with primer LRLacILP-NdeI-for-out and primer LRLacILP-KpnI-rev-out.
 
-
 
-
(2) Fragment Fusion
 
-
Fuse LacI(LVA) and CRE(T7ter) together and amplify with the primer LacILVA-HindIII-for and CreT7ter-EcoRI-rev-out;
 
-
Fuse PrPhaR and LoxPLacILoxP together and amplify with the Primer PR-PhaR-NotI-for and LRLacILP-KpnI-rev-out.
 
-
We’ve tried to fuse more by PCR, but failed.
 
-
(3) Vector preparation
 
-
We choose pACYCDuet-1 as our second vector while PhbCAB operon is cloned into PUC18.
 
-
Since lacI is one of the elements we also used in our own system, we knocked out the lacI coding region in pACYCDuet-1 successfully.
 
-
(4) Cut and Insert
 
-
The restriction enzymes are chosen as following:
 
-
Fragment Enzyme A Enzyme B
 
-
SRRz/EGFP NcoI BamHI
 
-
PpPhaP NotI HindIII
 
-
LacI(LVA)Cre(T7ter) HindIII SacI
 
-
PrPhaRLoxPLacILoxP NotI KpnI
