PCR amplification of Moth_1191, 1199 gene : decreasing annealing temperature down to 45℃
To make sure there’s no problem with unspecific binding or annealing temperature, we decreased annealing condition down to 45℃.
Results
There was no band and it became certain that there are no problems with annealing procedure.
Induction of Moth_0109 gene (sampling) and running SDS-PAGE gel.
We induced Moth_0109 gene in pBAD/myc vector with different Arabinose conditions and temperature: 10mM, 30mM and 37℃, 30℃. And then, we run the sample into SDS-PAGE gel. The gel is stained with coomassie blue for 1 hour and de-stained for overnight.
PCR amplification of Moth_1191, 1199 gene with Gibson and TOPO primer
To see whether there are any problem with Gibson primers that we’ve designed, we did one more pcr amplification. Primers for Gibson assembly and TOPO cloning are mixed, and we could see any problems with forward or reverse primers.
Results

Discussion
For each samples of different induction conditions, we run SDS-PAGE gel and checked the presence of 40.xx kDa protein, formate dehydrogenase. The band appeared more significantly than the case of pTrcHis2A vector. Therefore, using pBAD promoter seems to produce more proteins.

As the band was not significant for 1203 and 1198 on previous trial and purity was low for 1191, we tried secondary PCR amplification on samples for Gibson assembly; 1202, 1203, 1198, 1191.

Primer design for Bxb1 integrase cloning
Primers for Bxb1 integrase cloning were designed. For controlling basal transcription level optimization, a mutant primer which has GTG rather than ATG for its start codon was also ordered.

0109, 1191 PCR with new primers
Results
Discussion
PCR product of Moth 0109 gene and 1191 gene has run on the gel. There was only faint band of 0109 fragment but the product band of 1191 gene was significantly shown on the gel. After gel electrophoresis, we tried PCR of 0109 once more and got significant amount of fragments.

In confirm PCR, all the colonies seem to have Bxb1 vector. Colony #1, 4, 7, 10, 13, 14, 16, 19 and 22 will be inoculated.
Bxb1 PCR with new primers
For cloning of Bxb1 into pBAD and mutating its start codon from ATG to GTG, we PCR pGEM-B1-Bxb1 vector as template. Samples were duplicated
PCR conditions
- 95℃ for 3min
- 95℃ for 30sec
- 55℃ for 30sec
- 72℃ for 1min 30sec Step 2 to 4: 34 cycles
- 72℃ for 10min
- 12℃ forever
pGEM-Bxb1 template vector gel electrophoresis
To check whether the undesired bands were template vector, we diluted template vector with same conditions of PCR, 50X, and electrophoresized.
Results
Discussion
The band was different from undesired bands from Bxb1 ATG, GTG PCR products.

Still, undesired bands appeared. We do not know where they come from. We decide to extract desired DNA with gel extraction.

The gel showed that all the colonies have Bxb1-pTrc vector. And also they all have pPoC or pPoCpi, because they show color.

1202 PCR to make fragments for Gibson assembly
Results
Discussion
PCR for Moth 1202 gene has failed. No band for Moth 1202 gene has appeared on the gel.
Gibson assembly – assembly of pcr fragments.
Results
Among three methods to assemble DNA fragments, we chose first method, which is assembly of PCR amplified DNA fragments.
0.2umoles of each fragments are added into the reaction sample, and volume to be added for each fragments has calculated on the assumption that average MW of each base is 660Da. Table below is the result of calculation.
Fragment 1
Fragment 2
Discussion
As we can only assemble the fragments through Gibson Assembly method and not amplify them, there would be very small amount of template remaining in the tube. We thought that’s why we couldn’t see any band on the gel. So we did PCR purification of the fragment once more and saw if the band appears on the gel.

Gibson Assembly product – Amplification by nested PCR
Results
Discussion
There was no right size of the band but just unspecific bands on the gel.
There might be several reasons why the Gibson assembly ended with failure. So we decided to change the method of Gibson assembly; we will assemble fragments in the presence of vectors, so that assembly product can become stable, circular form. To cut the cost used in experiment, we will not design primers, but digest the vector with restriction enzymes to make it linear form.
Gibson primer second design 2
Results
Discussion
We designed primers again for another trial of Gibson Assembly. As stated before, We’ll use vector-involved assembly method to stabilize the assembly product and amplify them by in vivo system. Like the method we used before, we’ll assemble 5 fragments first and assemble those 5-fragment-long two fragments into full construct.
