Electrophoresis analysis.
We got the expected bands in all cases.
01/07/2014
AtrΔ11 amplification by PCR with primers that contain extra nucleotides to introduce them in the sequence.
We made a PCR amplification using the AtrΔ11 gene as a template and the oligos: R +F
Reagents needed:
- 32.5 μL of H2O miliQ
- 10 μL HF buffer
- 2 μL dNTPs
- 2.5 μL Reverse primer
- 2.5 μL Forward primer
- 1 μL template (AtrΔ11 gene)
- 0.5 μL phusion (polimerase)
PCR parameters: The annealing temperature was 60ºC and the extension temperature was 65ºC.
Electrophoresis performed to check the PCR product, which was expected to be around 1 kb.
pUPD ligation of EaDAcT, HarFar and AtrΔ11
Reagents needed for the reaction of ligation:
- 1 μL pUPD
- 1 μL PCR product/gblock product
- 1.2 μL buffer 10x
- 1 μL BsmBI
- 1 μL T4 ligase
- 6.8 μL H2O miliQ
Vfinal= 12 μL
Termocycler parameters: The ligase temperature was 16ºC and the BsmBI temperature was 37ºC.
As a result, there are obtained three different pUPD plasmids containing the genes EaDAcT, HarFAR and AtrΔ11.
07/02/2014
E. coli transformation
This step is performed in a laminar air flow cabinet (LAF).
We have used an electrocompetent E. coli strain (DH5α) and a sample from each product of ligation made in the previous step (three pUPD plasmids, each of them containing one of the three genes), so transformation is made three times.
Reagents needed:
- E. coli aliquot
- 1.5 μL of ligation in pUPD (for each gene: EaDAcT, HarFAR, AtrΔ11)
Each mix is introduced in a electroporation vial and electroporated at 1500 V, then 300 μL of SOC are added to each vial. All of them were incubated at 37ºC for 1 hour.
After incubation, culture in Petri plates (always in a LAF).
2 cell-culture dishes per transformation (with Ampicillin), one with 50 μL and the other with the remaining volume.
Petri plates are incubated at 37ºC for 16 h.
07/03/2014
Transformed colonies selection. The white ones are recultured in liquid medium. One colony of each transformation is picked and cultured in 3.5 mL LB and 7 μL Amp. This step is repeated three times:
- 3x 1 colony of EaDAcT in pUPD + LB + Amp
- 3x 1 colony of HarFAR in pUPD + LB + Amp
- 3x 1 colony of AtrΔ11 in pUPD + LB + Amp
All tubes are incubated at 37ºC overnight in agitation.
07/04/2014
Digestions in silico using Vector NTI to check after minipreps if ligations are correct.
EaDAcT | NotI | 2981, 1167 |
RsaI | 1876, 1343, 532, 306, 91 | |
HarFAR | NotI | 2981, 1440 |
PvuII | 2564, 1394, 463 | |
AtrΔ11 | NotI | 2981, 1056 |
BanII | 2570, 803, 351, 314 |
Digestion reagents:
- 0.5 μL restriction enzyme
- 2.5 μL buffer
- 21 μL H20 (miliQ)
- 1 μL sample
Preparation of master mixes
- Master mix for NotI
- 5 μL NotI
- 25 μL Orange
- 210 μL H20
- Master mix for RsaI
- 1.5 μL RsaI
- 7.5 μL Tango
- 63 μL H20
- Master mix for PvuII
- 1.5 μL PvuII
- 7.5 μL Green
- 63 μL H20
- Master mix for BanII
- 1.5 μL BanII
- 7.5 μL Tango
- 63 μL H20
Perform electrophoresis to check if the size of the fragments from the digestions is correct.
Comments:
- We picked blue colonies instead of white by mistake. We need to pick colonies again but this time make sure we pick white colonies.
- For the repetition we must find another enzyme instead of BanII as we found out that it doesn't cut very well.
07/06/2014
We picked again 3 colonies for each construction, and we made sure that we picked the WHITE ones. We cultivated them in a "double check" (name invented by us) liquid medium. Those tubes contain:
- 3.5 mL LB
- 7 μL Amp
- 7 μL X-Gal
- 3.5 μL IPTG (turns the tube blue if the colonies picked were blue)
07/07/2014
We made minipreps of yesterday's culture. Thanks to our "double check" medium we found which colonies were well picked. Finally we had minipreps of tubes HarFAR 1, 2, 3; EaDAcT 3 and AtrΔ11 2, 3.
Once we had the minipreps, we perform the digestions to check which were correct and send them to sequencing. This time we selected RsaI instead of BanII. The in silico digestions were as follows.
EaDAcT | NotI | 2981, 1167 |
RsaI | 1876, 1343, 532, 306, 91 | |
HarFAR | NotI | 2981, 1440 |
PvuII | 2564, 1394, 463 | |
AtrΔ11 | NotI | 2981, 1056 |
RsaI | 1879, 1310, 467, 327, 54 |
Preparation of master mixes
- Master mix for NotI
- 3.5 μL NotI
- 17.5 μL Orange
- 147 μL H20
- Master mix for RsaI
- 2 μL RsaI
- 10 μL Tango
- 84 μL H20
- Master mix for PvuII
- 2 μL PvuII
- 10 μL Green
- 84 μL H20
We run the electrophoresis gel to check if this time we have done it correctly.
Everything was OK. We sent AtrΔ11 (3), HarFAR (3) and EaDAcT (3) to sequence.
07/08/2014
Now, while we wait for sequencing results, we go on as they were going to be correct in order to save time.
The next step is to build a transciptional unit (TU) with our sequences. A transcriptional unit is a structure composed by promoter, coding sequence (CDS) and terminator in an α or Ω vector.
Reagents needed for ligation:
- 1 μL promoter 75 ng/μL
- 1 μL terminator 75 ng/μL
- 1 μL CDS 75 ng/μL
- 1 μL vector α
- 1.2 μL ligase buffer 10x
- 1 μL T4
- 1 μL BsaI
- 4.2 μL H20
Total: 12 μL
Take into account that if we want to make binary constructions later (merge 2 TU in a same vector), we need to clone each TU in a different α vector.
Strategy Promoter-Terminator:
AtrΔ11 | P35s | T35s | 40.41 |
HarFAR | P35s | TatHSP | 39.68 |
EaDAcT | PAtUbq | TatHSP | 32.27 |

pTatHSP | 235.4 ng/μL | 36 μL | 77 μL |
T35s | 194.9 ng/μL | 37.5 μL | 60 μL |
P35s | 454.7 ng/μL | 36 μL | 182 μL |
2α1 | 57.1 ng/μL | - | We will need to put 1.5 μL of this one |
2α2 | 104.0 ng/μL | 38 μL | 14.7 μL |
AtrΔ11 | 359.3 ng/μL | 20 μL | 75.8 μL |

Transformation of constructions in E. coli
We finally got the sequencing results from 07/07/2014.
- Mutation in AtrΔ11 -> We threw away the colonies and transformed cells. We picked again white colonies.
- HarFAR -> Sequencing correct
- EaDAcT -> Synonim mutation in 601 (A -> T). This is a gBlock!
We took vectors 2Ω1 (GB0487) and 2Ω2 (GB0488) parts from the GB colection.

- Cultivated in a Petri dish with Spm
- Let them grow for one day
Cultivate transformated cells in two Kan plaques (Kan matches vector α)
- 50 mL transformation in one plaque
- Rest of the culture in another (250 μL aprox)

Grow at 37ºC in agitation overnight.
We have checked the promoters and terminators are both compatible with GB and BioBricks.
Only P35s and T35s work for both. pPnos could also work.

07/11/2014
We made minipreps of yesterday's liquid culture. Thanks to our "double check" medium we found which colonies were well picked. Finally we had minipreps of tubes AtrΔ11 3 and 6; 2Ω1; 2Ω2; constructions P35s:HarFAR:TatHSP 1, 2, 3 and PAtUbq:EaDAcT:TatHSP 1, 2, 3.

As the digestions of the transcriptional unit (TU) of EaDAcT were incorrect, we repeated the process from the ligation step.
We transformed the same TU in a E. coli competent strain (DH5α). Then, the transformants were cultured in LB media and Spm and stored at 37ºC overnight.
Pieces taken from the GoldenBraid 2.0 collection were cultured in solid growth media:
With Amp:
- pTNos (GB0037)
- pGFP (GB0059)
- pLuciferase (GB0096)
With Kan:
- P35S:Rosea:TNos
- TA29:Barnase:TNos (GoldenBraid 1.0 piece)
Finally, in order to obtain the FAO1 gene, we want to extract the Candida tropicalis genome, so we have picked a colony of C. tropicalis. To check the extraction protocol, we used a yeast previously tested, Saccharomyces cerevisiae. We have cultured C. tropicalis in YPD media and S. cerevisiae in YPDA media at 28 ºC (5 mL).

Candida genome extraction
Saccharomyces cerevisiae is used as a control in order to see if we followed the protocol correctly. We aren't really sure if this protocol is going to work in Candida.
Cultures measured at 600 nm:
- S. cerevisiae Abs = 1.07
- C. tropicalis Abs = 0.39
S. cerevisiae is recultured with new media (1:2) because the previous media was saturated. 2.25 mL of YPD media were mixed with 2.25 mL of S. cerevisiae culture. The mix has to grow at 28 ºC until the exponential phase is reached.
The absorbance was measured again:
- S. cerevisiae Abs = 0.52
- C. tropicalis Abs = 0.40
Buffers needed for the genome extraction were prepared freshly.The genome of both strains of yeast were extracted following the protocol:
- Grow yeast in 2 or 5 mL YPD to exponential phase.
- Collect cells in 1.5 mL eppendorf-cup (centrifugation 20 s, 6000 rpm).
- Wash once with 1 mL sterile water.
- Resuspend cells in 200 μL protoplast-buffer (100 mM Tris-HCl, pH 7.5, 10 mM EDTA, 1000 units Zymolyase/mL, 10 μL beta-mercaptoethanol/mL; prepare freshly!). Incubate at 37ºC for 1-2 h and finally resuspend by turning the cups.
- Add 200 μL of Lysis-Mix (0.2 M NaOH, 1% SDS) an mix carefully (Don't vortex!).
- Incubate at 65 ºC for 20 min and cool inmediately on ice.
- Add 200 μL of 5 M KAc (pH 5.4) and mix carefully (Don't vortex!) and incubate 15 min on ice.
- Centrifuge (13,000 rpm, 3 min) and transfer supernatant in a fresh cup.
- Add 2 μL RNase A (10 mg/mL) and incubate at 37 ºC for 30 min.
- Add 600 μL isopropanol and mix carefully (Don't vortex!). Incubate at room temperature for 5 min ad centrifuge (13,000 rpm, 30 s).
- Remove the supernatant and wash with 70% ethanol (10 min at room temperature).
- Centrifuge (13,000 rpm, 30 s) and remove the supernatant.
- Dry DNA pellet in a speed-vacuum (not longer than 3 min!) and resuspend in 50 μL TE-buffer.
- Store chromosomal DNA at 4 ºC (Don't freeze!). Concentration and quality can be checked in an agarose gel (loading 1/10 of the volume).
Genomic quantification:
Organism | Concentration |
S. cerevisiae | 72.2 ng/μL |
C. tropicalis | 1397.1 ng/μL |
Electrophoresis made to check the extraction quality was correct.
We did not observe genomic from Candida because we used a very diluted sample. We will repeat the gel tomorrow.
EaDAcT and collection pieces made yesterday were recultured in liquid media.
07/24/2014
The genomic quality of both organisms (C. tropicalis and S. cerevisiae) was checked in an agarose gel again.
We got the Candida genome band, however, the Saccharomyces genome band was not present.
Additionally, minipreps of the liquid culture made yesterday were made and also recultured in solid agar plate.
