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

[Collapse]

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 August)

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.

[Collapse]

Week 7: (9-15 August)

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.

[Collapse]

Week 8: (16-23 August)

We made colony PCR for all of our genes.

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

37 °C 2h cut check %1 AGE (100 V, 30 ‘)

-Add 1 unit of CIP for every 1 pmol of DNA ends(about 1 mg of a 3 kb plasmid.

37°C 30 mins, 50 °C 30 mins.

Purified DNA hg spin-column

Check concentration by ND.

psB1C3(E,P), J23115(S,X) are digested. pSB1C3 and J23115, E0240 ligated.

I20260 is made liquid culture.

In measurement study, General Check of uncut , digested or even ligated samples.

Our transformation didn’t show up lately.So we decided to revise our steps.

Result:

• It doesn’t seem there is 30 bp part on digested J23101(Problem)

• There isn’t anything on I23115 digested.Digestion failed.

We checked our genes ODD,HRE,NFKB,PLAT,GPX,SOD with colony PCR.

PLAT-iGEM vector was DNA isolated.

Plat-igem was digested and run gel and the results are below.

Measurement Study :Miniprep and digestion of J23101(E and S)

• SOD, GPX, PLAT, ODD, HRE, NK-RE Enzyme restricted wit vectors.

We obtained our expectated experiment results. We saw our correct bands in electrophoresis.

Conclusion: We sequenced our genes, PLAT/HRE/NK-RE

• Pick into 17 colonies 50 µl ddH2O.

• incubate 95 °C 5 min

• 5 µl Template and 20 µl Master mix added to tube.

[Collapse]

Week 9: (24-31 August)

1. We discussed with Turkish Heart Foundation.

2. We sent our Measurement Study ‘s results to iGEM.

pTRE-luc , pTet-off digestion By:Ramazan Cetin

We measured our SOD, ODD density in ND.

• We had a Victory Eid between 29.08-31.08. So had a break these dates.

[Collapse]

Week 10: (1-8 September)

Clonning of ODD domain into pTet-off vector

Sequencing of ODD &pTRE

ODD-pTet-off throwing experiment By:ATOMS

The result of our experiment we saw the C12 was entered the pTet-off vector. But when we fixed the direction of ODD, unfortunately, that was wrong.

This experiment we sequenced ODD,Aprotinin and GPX and therefore made Colony pcr for our gene’s quality.

There was a eppendorf(1,5) which unknown product in it,pTet-off or pTet-ODD.So we cut unknown material with SalI,EcoRI,BamHI+EcoRI..

Conclusion:We learned it was pTet-ODD. Someone put into it wrong sample.

[Collapse]

WEEK 11;(9-16 September)

We digested pTet-off and pTet-ODD with SalI.

Then we Salı and B-E run in gel for control and the result is below.

PCR(PLAT;SOD;GPX) and ODD-pTRE Cut check Made by:ATOMS

We controled our Plat,Sod,Gpx again and again because we couldn’t get our expectations on experiments.

Hre,pTRE,digestion(Enz:ECoRI) by:ATOMS

And the same day we also digested pTet-off and pTet-ODD With E-B

Initially, we checked HRE’s digestion and chose the correct insert.

Later we wanted to threw HRE to PSB1C3 but we didn’t get result again.What a Shame!!

Gradient for SOD,GPX and PLAT.

Pus:60-60,9-62,4-64.5-67.2-69.6-71.1-72

And we controlled lig . of pTet-off and pTRE-ODD.

Measurement of our promoters J23101,J23115 efficiency in our BioBrick.

[Collapse]

WEEK12: (17-23 September)

Plat PCR-Gradient + NFKB Cut-check

2 µl Ladder used.PCR product length was 1700 bp.For NFKB, correct band was 350(with correct insert). If we saw band in 300, it means insert didn’t enter to Vector.But we didn’t see these bands. Maybe our SmaI enzyme didn’t work.

GPX,SOD and PLAT Digestion and Measuring

That day we made ‘Digestion Party’. We cut pTRE and pTRE-luc with all of our enzymes for restriction sites.

And we measured pTRE-HRE.

One day later we(ATOMS)checked our Measurement Study samples.That was we expected fortunately.

SOD-pTRE,GPX-pTRE,Plat-pTRE colony PCR

We cut our samples which correct result in ColonyPCR, with EcoRI and BamHI.1,3,4 and 7 was cut.The others didn’t reply our enzymes that unknown reason.

In 20.09 we started working in our cell culture room and tried our genes in eukaryot cells

We measured our pTRE-luc quality and graphic is below.

HRE 50-60 °C GRADIENT, By:ATOMS

We replicated our HRE using M13 primer in PTZ57R vector.

We wrongly gradient’s temparature 60-72°. After 30 mins, altered to 50-60°.In our opinion,in high temparature,our primers linked non-spesific so we saw extra bands in EPH.
