August 1st

Since it takes at least one month to establish transgenic flies, we decided to first construct the P-element plasmid for microinjection into Drosophia embryos.

We performed PCR in the following conditions.

1. PCR product check

We run 0.7% agarose gel electorophoresis in the following conditions.

   8/1 the attB TNFAIP3 PCR products 
 DNA sample  10μL 
 6×Dye  2μL 
 total  12μL 

The order of sample application
Left to right: 1kb marker(5uL), attB TNFAIP3, attB API2-MALT1-1, -2, -3, -4


2. DNA purification from gel
We electrophoresed in 0.7% agarose gel in the following conditions.

   8/1 attB TNFAIP3 PCRproduct 
 DNA sample  90μL 
 6×Dye  18μL 
 total  108μL 

We applied half of 108 uL of sample to each of two lanes of Agaroe gel with 5uL of 1kb marker.Then we detected the DNA band in the gel.


We purifed DNA from the gel by QIA Quick Gel Extraction Kit.

・Eatimation of the amount of attB TNFAIP3 DNA fragments by electrophoresis.
Order of samples applied to the agarose gel
The samples were electrophoresed in 0.7% agarose gel in following order.

Right to left:3uL of 1kb marker 1uL of 5 fold dilution of attB TNFAIP3 DNA fragments,1uL of 10 fold dilution of attB TNFAIP3 DNA fragments, 1uL of 20 fold dilution of attB TNFAIP3 DNA fragments, 1uL of 1kb marker.


We have estimated amount of the attB TNFAIP3 DNA to be 80ng/uL.

1. BP reaction

BP reaction was carried out in the following conditions.
 attB TNFAIP3(80ng/μL)  1μL 
 pDONR(455ng/μL)  0.35μL 
 TE buffer  7.65 
 total  9μL 

One uL of BP Clonase Ⅱ enzyme mix was added to this solution and incubated for 2.5 hours.

2. Transformation of E.coli by BP reaction products
2uL of BP TNFA reaction product was added to 100uL of E.coli XL1-Blue to do transform ation.
At last, cells were divided into 10,40,100,and 200 uL,and spreaded on LB Kanamycin(+)plate,Plats wera incubated for 16 hours at 37°C.

August 4th

Four independent 4 colonies were picked up from the plate incubated from 8/3 as described in ②,then cultured in 2.5mL of LB Kanamycin(+) liquid culture medium for 16 hours.

August 5th

Plasmid DNAs were isolated from E.coli cultured in 4 of LB liquid culture medium which we made on 8/4 by the alkaline-lysis method, we added the DNA to 20uL TE and added 10uL of the solution to 2uL of 6×Dye. Then we electrophoresed it with marker, 2uL of pDONR+ 2uL of 6×Dye+ 8uL of TE,in 0.7% agarose gel in following order (from left to right)

Left control pDONR DNA, BP TNFA-1,-2,-3,-4


August 6th

E.coli carrying the plasmid sample -1 and -2 in LB Kanamycin(+)liquid culture medium for 16 hours.

August 7th

1. Purification of candidate pENTR-TNFAIP3
We purified candidate plasmid-1 and -2 by QIA Prep Spin Miniprep Kit, dissolved it in 30uL of Buffer EB.
Then,the samples were electrophoresed in 0.7% agarose gel.

We made samples as follows.
 DNA sample  1μL  1μL  1μL 
 6×Dye  1μL  1μL  1μL 
 dH2O  4μL  4μL  4μL 
 total  6μL  6μL  6μL 

We electrophoresed them in following order.
Left marker 5uL control pDONR DNA ,pENTR-TNFAIP3-1 DNA,pENTR-TNFAIP3 -2 DNA marker 4uL marker 3uL Wright.


Concentration of pENTR-TNFAIP3-2 DNA was estimated at around 100ng/uL.

2. LR reaction
We made following solution(vials)in 1.5mL tube.
 BP TNFA-2  2μL 
 pTFW(Destination vector)  0.5μL 
 TE buffer  6.5μL
