1. Reconstruct pUC18 plasmid, insert GFP to the downstream of lac promoter
+
-
+
-
1.1 Use touchdown PCR to amplify GFP and add degradation tag and terminator.
+
-
Primers:
+
-
Forward: 5’- GA    GAATTC  G  AGCAAGGGCGAGGAGCTGTTCACCG -3’
+
-
 
+
-
Reverse: 5’- CTTG  CCCGGG  TTATCACTTGTACAGCTCGTCCATGC -3’
+
-
 
+
-
(''Template: provide by Guoqiang Chen’s lab in Tsinghua University'')
+
-
 
+
-
1.2 Cut pUC18 plasmid with EcoR I and KpnI. Purify the cut pUC18 from agarose gel with Kit.
+
-
 
+
-
1.3 Purify the PCR product GFP from agarose gel with Kit and cut with EcoR I and Kpn I.
+
-
 
+
-
1.4 Purify the cut GFP with column.
+
-
 
+
-
1.5 Run a gel to compare the concentrations of the fragment and vector in order to decide their volume in the ligation mixture.
+
-
 
+
-
1.6 Incubate the ligation mixture at 16 degree.
+
-
 
+
-
1.7 Use 10μl ligation mixture to transform 200μl DH5αcompetent cell, spread on the LB plate(Amp), and incubate at 37 degree over night.
+
-
 
+
-
1.8 Pick three clone to 5ml LB and shake at 37 degree for 12h, miniprep the reconstruct plasmid.
+
-
 
+
-
1.9 We sequenced the inserted part and it was right.
+
-
 
+
-
2. Synthesize the Nde I-Pm(complementary chain)-Pst I-Xba I-cad-Spe I-RBS(strong)-CI+LVA tag-Sac II-T1, T2-BamH I (the Blue part is the synthesis sequence) sequence. We use synthesis because we cannot use PCR to get the sequence from Staphyloccocus aureus Rosenbach
+
-
3. Insert CheZ(with tag and terminator) into the reconstruct pUC18(with GFP)
+
-
3.1 Extract the genome of E.coli DH5αstrain and use PCR amplify CheZ from it.
+
-
Primer:  
+
-
Forward primer:
+
-
5’-GTCATGCC  CA TATG  CAACCATCAATCAAACCTGC-3’
+
-
Reverse primer:
+
-
5’-AT    AGG CCT  AAATCCAAGACTATCCAACAAATCGTCCACCTGATC-3’
+
-
3.2 Purify the PCR product from gel and then cut with Nde I
+
-
3.3 Cut the pAcYc duet-1 plasmid with EcoR V and Nde I
+
-
3.4 Run a gel to compare the concentration of the vector and insertion in order to decide the their volumes in the ligation mixture
+
-
3.5 Ligate the vector and the cheZ, transformate DH5α and spread the LB plate(Chl).
+
-
3.6 Pick three clones to 5ml LB(Chl) and shake at 37 for 12h, then miniprep the reconstruct the plasmid.
+
-
3.7 Synthesize the Stu I-tag-Hind III-T0/T1T2-AatII sequence (with stick end), which contains CheZ’s tag and terminator. We firstly synthesized the sequence as two single strings, and then annealing them together as a double string DNA.
+
-
The two single strings’ sequence is below:
+
-
Forward
+
-
5’-CCT  GCTGCAAACGACGAAAACTACGCTTTAGTAGCT  TAA      A AGCTT
+
-
Stu I end  LVA tag                              stop codon  Hind III
+
-
CGCAAAAAACCCCGCTTCGGCGGGGTTTTTTCGC  GACGT-3’
+
-
T0                                      Aat II end
+
-
Reverse
+
-
5’- C  GCGAAAAAACCCCGCCGAAGCGGGGTTTTTTGCG  A AGCTT  TTA
+
-
Aat II end      T0                                Hind III      stop codon
+
-
(complementary)
+
-
AGCTACTAAAGCGTAGTTTTCGTCGTTTGCAGC    AGG
+
-
LVA tag (complementary)                  Stu I end
+
-
3.8 Cut the pAcYcduet-1-cheZ plasmid with StuI and Aat II and column purify the vector
+
-
3.9 Run a gel to compare the concentration of the vector(pAcYcduet-1-cheZ) and insertion (Stu I-tag-Hind III-T0/T1T2-AatII) to make sure their volumes in the ligation mixture.
+
-
3.10 Ligate the two parts    transformation    spread plate    pick 4 clones    shake and get the reconstruct plasmid
+
-
3.11 We sequenced it and it was right.
+
-
3.12 Then we cut the whole CheZ-tag-terminator with NdeI and AatII and ligate the fragment into the pUC18-GFP vector, which is cut by the same two enzymes.
+
-
3.13 This sequenced this plasmid and the sequence was right.
+
-
4. Cut the synthesized Nde I-Pm(complementary chain)-Pst I-Xba I-cad-Spe I-RBS(strong)-CI+LVA tag-Sac II-T1, T2-BamH I (the Blue part is the synthesis sequence) sequence with BamH I and Nde I, the same was done on the vector(pUC18-cheZ-tag-ter-GFP). Then ligate them together and got a new reconstruct plasmid. It was also sequenced.
+
-
5. Put RBS-CI-tag into last vector.
+
-
5.1 Use PCR to amplify CI from lambda DNA, adding RBS to 5’ and tag to 3’
+
-
First round primers:
+
-
5’-GAGGGGACAAactagt  ATGAGCACAAAAAAGAAACCATTAACACAAGAGC-3’
