fdh pBAD, fdh pTrc colony PCR check
Results

0818Fig1


Discussion

To check the presence of FDH gene, we picked the colony from the plate and did colony PCR. For all the colonies we picked, we confirmed that correct size of FDH is present.

Bxb1_GTG_pBAD cloning with remaining DNAs
Remaining Bxb1_GTG insert was cloned into pBADmycHisC vector. And electrotransformed into MG1655.

Discussions

All the vectors showed right sizes. But Bxb1_GTG_pBAD colony #1 through 3 have undesired bands. They may be the supercoiled vector.

1201 1197 1198 1516 PCR for Gibson assembly.
Results

0818Fig1


Discussion

There was no band for 1516 gene. Band of all three genes appeared at the right size.


1516 PCR for Gibson assembly.
Results

0818Fig1


Discussion

Also for this time, there was no right size of band appeared for 1516 gene.

We,
1. changed the fraction of primers down to 0.5ul each, (lane 1)
2. changed the polymerase to pfu-x, (lane3)
3. used hybrid primers ( TOPO forward, Gibson reverse : lane 4 and TOPO reverse, Gibson forward : lane 5)
Lane 2 was the control experiment with Hotstartaq polymerase.



Pre-culture of piBR181 vector containing cells.
Procedure

We did 3ml pre-culture on five 10ml tubes for the cells containing each gene. Cell was grown about 16hours after pre-culture, and then induced with proper inducer.

Discussion

To amplify the amount of each fragment, we did PCR amplification of each gene once more. Correct size of bands appeared.


1197 1516 PCR amplification
Results

0818Fig1


Discussion

To amplify the amount of each fragments, we did PCR amplification of 1197 once more. And we did PCR amplification of 1516 gene once more with the same primers. Correct size of bands appeared for 1197 gene, but there was no band for 1516 gene. .

Results

2_0923Fig1

Discussions

There was too little full construct nested. We think this is due to primer interfering by its LVA homology.

To find out the right temperature for primer binding, we performed gradient pcr from 45℃~55℃. But, all the pcr products showed non-specific binding of primers, and we selected the most proper temperature.
