Ligate BBa_E0240.which doesn’t have ATG codons and pSB1C3
I have transformed E. coli DH5 alpha with it.
Before I made BBa_E0240.which doesn’t have ATG codons and pSB1C3.
The densities are 19ng/µl and 25ng/µl.
DNA samples were digested by the following restriction enzymes at 37 ℃ for 30 min.

After ligate them, I have transformed E. coli DH5 alpha with it.


Results

There aren’t any colonies on the plate.
However I heared the success probability is very low, so next time I want to be careful about the density.

I planned to give efficiency of the ligation by giving rise to the density of GFP and vector by ethanol precipitating


Results

I failed to rise the densities of vector and the DNA of insert.
We lost DNA In the middle of ethanol precipitation.

Results

The E.coli (DH5α) which contains pSB1C3 was increased, but there are some colonies which doesn’t correct color.
Possibly deterioration may begin in plate in itself.
The DNA of PCR reaction increased next day.

1.We carried out agarose gel electrophoresis to detect the PCR products.
2.We amplified Flag-tag dMLF by using the primer which I manufactured on 6th September.
Restriction enzyme processing.
This is because after examining a sequence of Flag-tag dMLF, a restriction enzyme site of PstI and XbaI was seen.
So, I examined whether PCR product of Flag-tag dMLF is cut by PstI and XbaI.

 total 30 µl
After incubate it in 37°C for 50 minutes, I performed electrophoresis with agarose gel.
Photograph after the electrophoresis.
3.To amplify Flag-tag dMLF cDNA, PCR reactions were carried out under the following conditions.
PCR reaction
10 µM Primer F1.5 µl
10 µM Primer R1.5 µl

Results

1.Image of the agarose gel.


2.Images of the agarose gel.

:
Flag-tag dMLF aren’t cut by restriction enzyme of PstI and XbaI.
A marker did not enough to drift.

1.We carried out agarose gel electrophoresis to detect the PCR products.
2.I extracted GFP, DNA of the vector from gel using [http://www.qiagen.com/products/dnacleanup/gelpcrsicleanupsystems/qiaquickgelextractionkit.aspx|QIAquick Gel Extraction Kit].


Results 1.Image of the agarose gel.


After doubling the density of gel, a marker did not drift.
I will decide to perform it with 2% of agarose gel about the electrophoresis of Flag-tag MLF in future.

2.I measured the density with an absorbance meter afterwards.

The BBa_E0240 succeeded in the extraction from gel and recorded 156ng/µl by the measurement with the absorbance meter and the pSB1C3 became 25ng/µl.
Therefore I decided to begin an experiment of the ligation again from the next day.
