Testing

Week 1: (23-30 June)

To check our cell’s transformation efficiency 5 bacteria plates are transformed with different concentrated plasmids(0,5-5-10-20-50 pg/µl)

There was no bacteria mass on plates,this results refer that our bacterias are not good enough foe engineering

Then we prepared new competent cells for our Project and we ordered our primers .

[Collapse]

Week 2: (1-7 July)

The ordered primers were taken this week.

We would produce our biobricks, but the result was not like we expected after electrophoresis. Then we made colony PCR and again do it for SOD and GPX. After this, we did digestion and also pTRE vector .

[Collapse]

Week 3: (8-15 JULY)

We prepared 14 pieces agar plates.

Plasmid isolation we did and gradient for PLAT and the optimal temparature was 62.4°. Therefore we did gel extraction for 1500-2000 bp bands.

Prepared liquid culture for DH5α and Neb10 E.Coli streamsfor obtaining competent cell.

Replaced grown cultures into 200 ml LB solution.

We did transformation efficiency for PLAT,SOD and GPX.

Gel extraction applied for PLAT and ligated with s3335(GFP) and after that transformed into our bacterias for cloning.

Therefore we digested pTRE , GPX , and SOD with EcoRI and SpeI.

We made colony pcr for plat

Week 4:( 16-23 July)

This week we digested BBa_K823012, psB1C3 (EcoRI and SpeI) and BBa_E0240 with XpaI and PstI and after that we did ligation psB1C3 with other our inserts, then transformation as usual.

We found a new biobrick for our Project and we digested it, ODD and pTet-off with SalI.

Ligation pTet-off and ODD

This week we tried our antibiotics and experienced our Kanamycin was broken . So we offered new one.

We digested Plat and iGEM vector(s3335) again and later ligated them.

• Transformation optimisation was made with 8 samples and we got this results.

[Collapse]

Week 5:( 24-31 July)

• ODD,colony pcr was made.

• PLAT-pTRE, PLAT-iGEM cut check was made also.In PLAT-pTRE cut check, we used SpeI and XbaI but we saw some bands that unnecessary.

• And also in PLAT-iGEM cut check we digested with BamHI. We saw 2 bands in electroforesis but they were not match with theoretical bands.

[Collapse]

Week 6: (1-8 Aug)

We made a general meeting.Decisions are below:

1. We hadn’t a Project name.

2. We hadn’t a Project scheme,Wiki,design.

3. We had to share our experiments and lab experience via Facebook,Twitter.

4. After our meeting we found our Project name:CHANGE OF HEART

• We started measurement Interlab study

• Initially, we did measurement B study. Two colonies were picked from measurement B plate. One of them is red, so RFP, the other one is colorless colony. This colonies were put to 5 ml LB broth with chlo. And waited for growing.(16 hours)

• Digestion, Measurement Interlab Study

Part 1:BBa_J23101(promoter) cut with EcoRI and SpeI.

Part 2: BBa_E0240 (GFP reporter) cut with XbaI and PstI.

Incubated them 30 mins and then 80° for 20 mnts.

Part 1 obtained from 2013 d. Kit plate 1 20k

Part 2 was old sample.

Result: Because of gene concentration and quality low, cut check didn’t Show up on monitoring after electrophoresis.

Decision: Before digestion, cloning genes via transformation is required.

SOD and psB1C3 measured efficiency of gel extraction kit and didn’t get require results. So we did electrophoresis again and examine our bands but they were too tiny. We didn’t get any result unfortunately.

Measurement Interlab study A

Transformation of J23101 and E0240 taken from plates.

After 16 hours the colonies begin seeing in part 2 plate. But the other plate was empty untill 20 hours passed.

Decision: Transformation was execuated again for part 1 plate. Additionally in case of we get result, these two parts would be taken from distribution kit and cut again.

GPX-iGEM vector dig-lig-trans.

Transformation

1.Competent cells stays in 10 min in ice.

2. 10 µl Dna +50 µl competent

3. 30 minutes in 37 °C waited

4. 2,5 mins in ice again

5. Incubate

Briefly, we couldn’t see any colony in plates and we returned start line.

• Sod-1, PCR(6 samples)

We also did Western Blot (15% SDS page).

For 1 mini gel

• SOD-1 and GPX -1 ,our transfection samples PCR.

We thought our samples was good but result of this experiment we started our experiments from the rough

We produced all of our genes.

Result: ODD and PLAT samples were correct.But GPX and SOD were not that we expected.

Week 7: (8-15 Aug)

1. We SHARED our missions in team.

2. We determined our Wki Design.

3. New members joined us.

4. Waiting for Aprotinin gene.

5. We chose our track:Health & Medicine

6. We wanted to try Measurement Study

iGEM Vector and SOD ‘ s Dig-Lig-Trans.

iGEM Vector(s3335) and SOD were digested (pSB1C3) with XbaI and PstI.

Ligation

Vectore 1+6/1

• We use the liver cancer tissue’s cDNA.We also check our enzyme’ s temparature by gradient.

• In measurement study, for step 1.2 and 1.3 , we replicated our parts with transformation. Also for step 1.1 , we replicated one part.

We obtained PLAT from gel extraction and digested.

Plat and iGEM were ligated and transformated to BL21 bacterias in choloramphenicol plates.

In measurement study ,E0240_1,E0240_2, I0260, J23115, J23101 are transformed to DH5α and BL21. Our some transformations were not that we expected. Because we used wrong antibiotic. E0240_1 , E0240_2 and I0260 are put into liquid culture. J23115 and J23101’ s transformation results were bad cause of wrong plates again unfortunately. Teh good samples were dig-lig-transformed.

Week 8: (16-23 Aug)

We made colony PCR for all of our genes.

Turan digested pTet-off , pTRE and pTRE-luc.
