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

0801Fig1

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

0801Fig2

Each lane indicates:

  • Moth_1191_1 : TOPO forward primer and Gibson reverse primer
  • Moth_1191_2 : Gibson forward primer and TOPO reverse primer
  • Moth_1199_1 : Gibson forward primer and TOPO reverse primer
  • Moth_1199_2 : TOPO forward primer and Gibson reverse primer

Correct size of band appeared when topo forward primer and Gibson reverse primer was used in amplification of both genes. Therefore, we can conclude that there is some unknown problem with forward primers.

Transformation of pTrcHis2A vector into TOP10 cell was successful. So we did vector mini-preparation after the transformation. However, transformation of pBAD vector has failed, so we ligated the samples again.

Procedure

We seeded cells (500λ of cells put into 50mL LB with 50λ Ampicillin) on 7 : 30 AM and checked Optical Density on 10:30pm. According to the O.D. value, we induced 37℃ sample on 10:30PM and did sampling on 4:30pm. Also, we induced 30℃ sample on 11:30pm and did sampling on 5:30pm.

Expression check of Formate dehydrogenase.
Results

0817Fig1

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.


PCR amplification – second trial
Results

0817Fig2

Discussion

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. Particularly for 1202 gene, we tried additional colony PCR, so that we could check any problem with vector mini-prep. (PCR solution for 1202 colony PCR was : 22ul

PCR amplification of 1202, 0109 gene with original primer and Gibson primers
Results

0818Fig1

Each lane indicates:

  • Moth_1202_1 : Gibson forward + original reverse
  • Moth_1202_2 : Gibson reverse + original forward
  • Moth_0109_1 : Gibson forward + original reverse
  • Moth_0109_2 : Gibson reverse + original forward

There was correct size and unspecific size of band on 1202_1 sample. Although there are also unspecific band, 1202_2 sample has large band of correct size. 0109_1 sample has only unspecific band and 0109_2 sample has right size of band.

Discussion

When the PCR was unsuccessful, we first thought it might be problem of forward primer as in the case of 1199 and 1191. Our guess was correct, and we’re going to fix the problem with forward primers.


1202 and 0109 forward primer design
We designed new forward primer hoping no problem with it.
