5 June 2015

We had 2 cultures from the last day, corresponding to other 2 colonies of ligation.

Agrobacterium culture of promoter less: Luciferase + Renilla

Minipreps

Digestion with BamHI and EcoRV

Agarose gel 1%

How to ask and make primers?

  • Select the sequence to amplify and save in FASTA format.
  • gbCloning, go to Tools-Domesticator-1º Category
  • Add FASTA and select parts.
  • On the protocol we have the primers
  • The oligos they give us:
    • 4 first nucleotides: so the enzyme can recognize without problems
    • 6 following bingind sites.
    • 1 extra nucleotide.
    • 4 overhangs.

Meeting with Daniel Ramón (Biopolis).

Ligation with part 2 and 24 of task sheet.

PIF6 + PhyB; ?1Etr8 CMV_Bxb1_T35S
1µL 892 (PIF α1)1µL 1097 (Etr8 CMV) Pupd2
1µL 88E (Phy α2)1µL Bxb1 (PuPD)
1µL ?1 1µL Tnos PuPD
1.2µL Buffer ligase1µL α1
1µL Bsmb15.8µL H2O
6.8µL H2O

If we make a digestion of 160 (35S:Renilla:tNOS-35S:P19:tNOS) with EcoRV, we obtain: 2475, 381, 4601 pb.

If we make a digestion of 896 (Luc:PIF6:PhyB)with EcoRV, we obtain: 11608, 3942 pb.


June 2015

Transform to E.coli from PIF+Phy and Bxb1

  • 1.5µL of ligation
    • Cuvette on ice
    • Competent cells + 1.5µL of ligation
    • Pulse (electroporator) at 1500V
    • Add 300µL shock medium and put Eppendorf 1h at 37ºC

Culture on petri dishes the ligations.

Digest of 160, 289 and the two ligations, PIF+phy and Etr8+BxbI.

Agarose gel.


7 June 2015

We’ve got white colonies! (from PIF+Phy and Bxb1)

Pick two colonies from each construction.

4 tubes

  • 3.5µL LB each tube

2) 2 tubes + 3.5µL Kanamycin (K)


8 June 2015

Minipreps of the 4 liquid cultures and digestion to see the band patterns.

Digestion:

Etr8(CMV):Bxb1:Tnos; ?1EcoRI6345, 238
EPIF6 + PhyB-PV16; ?1BamHI6686, 1439, 2685, 2237

Agarose gel was made:

Bxb1 (C1)Bxb1 (C2)EPIF6 + PhyB-PV16 (C1)EPIF6 + PhyB-PV16 (C2)
okok

Repeat digestion (errors).

We don’t have sure the toggle, so we decide to repeat the digestion with other enzyme tomorrow, noticing that the colony 2 has better bands pattern.

Optimized ligation of PIF-Phy-Lac-Renilla-P19

  • 1 µL vector
  • 0.8 µL dilution ½ 160
  • 1.7 µL big part
  • 1.2 µL BSA
  • 1.2 µL buffer
  • 1 µL BsbmI
  • 1 µL ligase
  • 4.15 µL H2O
  • Ratio 1:2 vector insert

As Bxb1 was good at the digestion we put 1 µL of LB and 1 µL of Kanamicyne on the tube where it had grown and store at 37ºC to glycerinate later.

We design primers to binding domain (BD) and PIF.

  • Problem: domesticator is introduced in an old pUPD. The new one has different bases.
  • Change manually the pUPD bases in the program (Benchling).

9 June 2015

Digestion of the ligation of yesterday containing: EPIF6-PhyB-VP16 (C1 y C2)

EPIF6-PhyB-VP16PvuII (green buffer)3663, 9472pb

Agarose gel 1%:

EPIF6-PhyB-VP16 (C1)EPIF6-PhyB-VP16 (C2)EPIF6-PhyB-VP16 (C3)
nonono

We see three bands: 7000, 4000, 1900pb

Transform optimized ligation (yesterday 8/6)

  • 3.5 µL ligation product (EPIF6-PhyB-VP16 + Luciferase + Renille + P19)
  • 40 µL electrocompetent cells.
  • Pulse of 1500V
  • Store 1h at 37ºC
  • Plate culture at agar with Spectinomycin: 50 µL of the transformation.

10 June 2015

  • Check the primers and order LexA, Gal4, PIF6, LacI, Dronpa.
  • Check linker VP16 (88E) and make a primer for it.
  • Take out glycerinate of Ω2.

Alfredo’s part is not working.

  • Pick colonies of transformation and make liquid culture of E:PIF6:PhyB:VP16:luc:ren (C1-C3).
  • Minipreps of liquid culture (PIF + Phy), colonies C3, C4, C5, C6
  • Digestion:

  • Transformation of Agrobacterium (C58) of the 896 construction (EPIF6-PhyB-VP16 + luciferase). We are not going to have the positive control and we won’t be able to quantify (we don’t have Renilla + P19).

11 June 2015

  • Minipreps of the culture:

Transformation in Agrobacterium of Renilla (160) due to that we could not join this with PIF:phyB and so we will do a cotransfection of both plasmids. Make petri dish culture with kanamicyn and rifampicin.


12 June 2015

The petri dish with PIF:phy:luc was taken out the 37ºC room and put into the fridge to pick colonies tomorrow.


13 June 2015

  • Pick colonies to make liquid culture:
    • Renilla in agrobacterium: just one colony, it was made liquid culture but check carefully the gel.
    • It was noticed that the piece 160, renilla, needs a pSub plasmid to replicate itself so we will transform 160 into a agrobacterium with this plasmid (C58 pSub).
  • Ligation:

BxbI; alfa1+phyB; alfa2

1µl BxbI

1 µl phyB

1 µl ?2

4.6 µl H2O

  • Transform renilla (160) into agrobacterium and make

  • Repeat the ligation BxbI+35S:E-PIF6:tnos because PIF was ?2

1 µl ?1

4.6 µl H2O

  • KDronpa has arrived:
    • Centrifuge it 2-5sec at max velocity.
    • Add 50 µl to have a concentration of 20ng/µl
    • Mix it with the vortex and spin.
  • Ligation: en la libreta pone que se liga a pUPD2

KDronpa; pUPD2

1 µl KDronpa

1 µl pUPD2

  • It was not possible to pick colonies of the Agrobacterium transformed because they did not grow. Maybe the problem is that with tetraciclyn bacterias grow slowly. Wait 1 day more.
  • Transformation of the ligation, BxbI + 35S:E-PIF6:tnos; ?1, into E.coli.
  • Make an agar culture in petri dish and let grow 16h at 37ºC.

16 June 2015

  • Transformation of the ligation, KDronpa, into E.coli.
  • Pick colonies of BxbI:E-PIF6 and make liquid culture (C1-C3).

We have White colonies of renilla! Also of Etr8 + Bxb1

We have also pUPD colonies but they are so close to the blue ones that we can’t pick anyone.So we make strakes in another plates to have the colonies separated.
