"Do not, for one repulse, forgot the purpose that you resolved to effort." - William Shakespeare

Wednesday 1/4

We started our work in the wet lab with a one-day lab safety course. We learned basic lab safety knowledge, such as how to put out a fire in the lab, how to deal with the poisonous chemical and the dangerous bacteria.

Thursday 2/4

We started to get familiar with our lab. We learned about where we can find everything that is needed for working in the lab. In addition, we had a lab meeting about the project goals and the way how to get there.

Friday 3/4

PCR reaction on pER41G-A

Gel purification was performed on the PCR product

The product was named as Ap-PCR(P)

Mix the Ap-PCR(P) and pHSE400

Digest the mixture with restriction enzymes: XbaⅠ-HF and SacⅠ

After four-hour digest, the product was purified with the silicagel column

Linkage

Link overnight

The product was named as pHSE-A

Saturday 4/4

Transform the Escherichia Coli (strain EP1300) with pHSE-A

Mix EP1300 and pHSE-A, 0℃ice bath 30min

42℃ water bath 90s

0℃ice bath 1min

37℃recover 1h

The transformed strain was plated out on the solid LB medium which contained Ampicillin (A100)

Sunday 5/4

There were many colonies growing up on the plate

Chose ten of them and scribed on another LB plate which contained kanamycin (K100)

Monday 6/4

Three bacterial colonies from the agar plate from yesterday were transferred to 3 bottle of fluid LB medium to amplify bacteria

Extract the pHSE-A plasmid from the bacteria

The plasmid was identified by enzyme digestion——XbaⅠ&SacⅠ, NcoⅠ&StuⅠ

The clone was right

Tuesday 7/4

Digest the pHSE-A and pUC57-BT/TB/BAG/GAB respectively with XbaⅠ-HF and StuⅠ

After four-hour digest, the products were then analysed on gel-electrophoresis and purified with the silicagel column

The products were named as pHSE-A-XS and BT/TB/BAG/GAB-XS

Linkage

Link overnight

The products were named as pHSE-BT/TB/BAG/GAB

Wednesday 8/4

Transform the Escherichia Coli (strain EP1300) with pHSE-BT/TB/BAG/GAB

The transformed strain was plated out on the solid LB medium which contained kanamycin (K100)

Thursday 9/4

Choose about 10 of the grown-up colonies respectively and scribed on another LB plate which contained ampicillin (A100) for invert selection

Friday 10/4

Choose the colonies which can grow on the kanamycin plate but can’t grow on the ampicillin plate

Colony PCR analysis

Two bacterial colonies from each agar plate were transferred to 8 bottle of fluid LB medium to amplify bacteria.

Extract the plasmid from the bacteria

The plasmid was identified by enzyme digestion——XbaⅠ-HF and StuⅠ

Send the sample to the company for sequencing

Monday 13/4

The result of sequencing is right

Transform the Agrobacterium tumefaciens(GV3101) with pHSE-BT/TB/BAG/GAB

The transformed strain was plated out on the solid LB medium which contained Gentamicin, rifampicin and kanamycin

Tuesday 14/4

Choose 3 of the grown-up colonies in each plate for colony PCR analysis

Choose one of each and transferred to 4 bottle of fluid LB medium to amplify bacteria.

Wednesday 15/4

Let the transformed Agrobacterium tumefaciens(GV3101) infect the wild type arabidopsis thaliana

16/4-10/6

waiting for seed bearing of arabidopsis thaliana. Because the standard biobirck plasmid is not a binary vector, we have to use our own plasmid to complete the experiment and then shift our genes to the pSB1C3 plasmid. We finish the shifting job while waiting.

Monday 20/4

PCR reaction on pVEL12C-EPC-A

Gel purification was performed on the PCR product

The product was named as A1508-(P)

Mix the A1508-(P) and pSB1C3-RpaR&I

Digest the mixture with restriction enzymes: XbaⅠ-HF and SpeⅠ

After four-hour digest, the product was purified with the silicagel column

Link for 4 hours under 16℃

The product was named as pSB1C3-A

Transform the Escherichia Coli (strain EP1300) with pSB1C3-A

The transformed strain was plated out on the solid LB medium which contained Ampicillin (A100)

Tuesday 21/4

There were many colonies growing up on the plate
