Sequencing of the previously picked clones revealed that the inserts were successfully cloned into pSB1C3. Sadly, apart from 453 Z34C every other insert contained various mutations (deletions, insertions, base exchanges in different positions). The reasons are unclear, probably difficulties with the fill in reaction or incorrectly synthesized oligos. We picked more clones from the last ligations' plates and carried out a colony pcr on them:

<p style="font-size:13px; color:red;"><b>Comment</b>:Strangely, PCR-products did not run into the gel, altough the PCR was repeated, after first PCR had two reverse primers in the sample. This could be because of a complex with the polymerase.However, ligation will be continued with the DNA within the bags. </p></br>

'''Investigator: Achim<br>'''
 +
 +
We sent in another clone of the 587 KO Z34C motif to see if it carries the same mutations as the first one. If that had been the case, we could account the mutations to faulty oligos. However, sequencing showed that the second 587 KO Z34C clone is mutated as well, but in different positions. So we either recieved oligos containing various mutations, or the fill-in reaction was faulty in spite of the proofreading activity of the klenow fragment.
 +
 +
Because 587 KO Z34C is one of our more promising approaches, we sent another two clones from our second colony pcr/clone picking round for sequencing: 13.1 and 13.4

Because somebody switched the 37°C thermoblock off i dont know the exact digestion time. Therefore i switched the thermoblock on again and waited 1 hour. I used that much DNA because the desired insert is 48 bp long.

<br/>
 +
<p scolor:#80080;"><b>Comment:</b> In order to target tumor cells with our AAV2 two VP2 fusion strategies were figuered out: The so called VP2-fusion and VP1 insertions. These approaches were successfully cloned and are now tested in cell culture. In order to prevent targeting of other (healthy) cells, the natural tropism of the virus needs to be knocked down. For this purpose a ViralBrick, "587-KO_empty", was designed and cloned into pSB1C3_001_VP2/3_Capins. <br/>
 +
Today this VP2/3_HSPG-KO sequence will be fused to the N-terminus of the Affibody, CFP/mVenus and His-Tag of both, the N-terminal fusion to VP2 and the VP1 insertion, approach. </p>

Sequencing showed that the PCR reaction we designed to remove the mutations in the z34c insert were successful! Both  pSB1C3_587_KO_Z34C and pSB1C3_587_KO_Z34C_Spacer are correct. We hadn't sent the 587_Z34C for sequencing because the colony PCR hadn't shown any bands.

The detected bands correspond to the expected sizes, but we cannot distinguish between the exact sizes because they are too similar. Therefore we sent P660 and P663 for sequencing in order to confirm if the ViralBricks have been successfully subcloned in the pSB1c3_VP2/3 construct.

* Comment: After 30 minutes of digestion I remembered that it would be adventageous to digest the plasmid backbone of the VP2/3 constructs. Therefore 0.5 µL of McsI was added to each sample - fortunately McsI does not have any restriction sites in the pGA14_MiddleLinker to which it was also added by mistake. <br/>

Continuation with Colony-PCR of pSB1C3_CD and ViralBrick motif Z34C

Investigator: Bea

Comment: Since the colony PCR of the last try did not work exactly the way we expected it, another colony PCR approach with new primers was conducted.


Loading plan:
upper lanes

M   CD1  CD2  CD3  CD4  CD5  CD6  CD7  CD8  CD9  CD10   +ctrl(CFP) +ctrl(BAP) -ctrl(pAAV_MCS)   11Q1  12Q1  13Q1 13Q2  M

lower lanes

M   11T41  11T42  11T43  11T44    12T41  12T42  12T43  12T44    13T41  13T42  13T43  13T44    14T41  14T42 14T43  14T44  M


Expected sizes of the PCR products are:

  • Cytosine deaminase (CD) = 1300bp
  • Z34C loops insertion motif = 220bp
  • Positive control 1 = CFP = 750bp
  • Positive control 2 = BAP_587 = 170bp


Results:
The Colony PCR of the Cytosine Deaminase (CD) did not work out. The detectable bands at around 700 bp correspond to CFP. Therefore, BioBrick production of the CD must be repeated. The following three bands represent the controls. Three different controls were used. The first corresponds to pSB1C3_CFP, the second to BAP_587 and third control is the negative control. Unfortunately now bands can be detected in the postive controls. A faint band can be seen in the negative control which is the only lane in which no band should be detectable.
The following bands after the three controls correspond to the approaches of the Z34C Viralbrick production. Some bands in the lower and the upper lanes show positive results. The corresponding inoculated overnight culture were centrifuged and prepared in order to perform a Mini-Prep tomorrow.

Comment: hmm, seems that the CD-assambly didn't work at all.. Should i try it again or are we gonna skip it for good due to other priorities?(kira)
No, we cannot skip it. Can we change something else?? Any ideas what we can alter in the protocol? Because problem is that we are still waiting for the tk... so we should aswell focus on the other prodrug activating enzmye!! (Bea)


Testtransduction of the final modified capsid coding constructs

Investigator: Adrian

Aim of the experiment:
During the project 22 silent nucleotide exchange mutations were introduced into the capsid coding construct to make it compatible with the RFC standards and to have single cutting restriction enzymes flanking the 453 and the 587 loop sequence. Two point mutations had to be dismissed, because either a first test transduction showed that the construct was not working anymore or the insertion of the synthesized gene posed serious problems, because the restriction enzyme did not work.
Finally, we have a construct that is shown to produce infectious particles comparable to the current AAV systems and carries 20 point mutations. Now we can announce that the Adeno-associated Virus is compatible to the RFC standard and the idea to replace the loop sequences via ViralBricks works!

Impression from the moment:

The construct with the insertion of the Rep and the Cap synthesis worked! Reintroduction of the KpnI restriction site recovered the functionality of the viral genome!

Miniprep of serveral constructs

Investigator: Stefan

Glycerol stocks were prepared:

  • B430 = pCerulean_ZEGFR:1907_Longlinker_VP2/3
  • B431 = pCerulean_CFP_Middlelinker_VP2/3_insCap
  • B432 = pCerulean_ZEGFR:1907_Shortlinker_VP2/3_insCap



Mini-Prep was performed according to the standard protocol

  • P527 = pCerulean_ZEGFR:1907_Longlinker_VP2/3 c = 230,61 ng/µl
  • P528 = pCerulean_CFP_Middlelinker_VP2/3_insCap c = 290,81 ng/µl
  • P529 = pCerulean_ZEGFR:1907_Shortlinker_VP2/3_insCap c = 269,39 ng/µl
  • Several other constructs were preped, but need to be confirmed before being added to plasmid/glycerol stock.


125. labday 20.09.2010

Picking the clones and preparing the over-night culture

Investigator: Kira

VP2/3_Gsat-linker as well as VP2/3_cap_Gsat-linker plates contain colonies, thus 3 clones from each plate were inoculated into 5 ml DYT+ 5ul Chloramphenicol and incubated @ 37 C

Sequencing results of ViralBrick ligations using dephosphorylated vector

Investigator: Achim

Sequencing confirmed a correct sequence for clone 11.4 (453 Z34C). Clone 12.1 (587 Z34C)has several missing bases at the 3' end of the insert, clone 13.2 has an a -> c mutation and a c insertion in the insert (although the a->c might be a sequencing error.). Clone 14.2 contained a c deletion.

We have several new approaches:

-Correction of the mutations via PCR: We'll use the hybridisation oligo for the side of the insert containing the mutations, the rfc 25 primer on the other side. The amplified insert will be ligated into dephosphorized vector.

-As a backup, SDM-primers will be ordered and should be available next week.

-Also, a new colony pcr with several clones from the last ligation plates will be carried out.

-clone 13.4 (already prepped) will be sent for sequencing

Cloning pSB1C3_Viral Brick 587KO-empty (B274/P542) into pSB1C3_VP2/3_Capins (B438/P514)

Investigator Patrick
After an over night digestion with BamHI and PvuII at 37°C ....

My dear friend - what do you mean with "..."?? overnight digest at which temperature?? Did you look it up whether the enzymes show star activity at longer digestions or not?? ;-)


The Gelextraction with P514 was performed according to the standard protocol yielding 16,9 ng/ml.
The P542 insert should be 48 bp long and therefore was extracted with a QIAGEN kit able to extract even very small DNA fragments (40 bp) (QiaEX II Gel Extraction Kit (150)).

Expected size of the fragments:
P542: 2112 & 48 bp
P514: 3956 & 48 bp

The 48 bp band of P514 can't be seen clearly on the picture due to the bad resolution.

Colony PCR of new clones from the last ligations

Investigator Achim

Sequencing of the previously picked clones revealed that the inserts were successfully cloned into pSB1C3. Sadly, apart from 453 Z34C every other insert contained various mutations (deletions, insertions, base exchanges in different positions). The reasons are unclear, probably difficulties with the fill in reaction or incorrectly synthesized oligos. We picked more clones from the last ligations' plates and carried out a colony pcr on them:

Contuniation: Cloning pSB1C3_Viral Brick 587KO-empty (B274/P542) into pSB1C3_VP2/3_Capins (B438/P514)

Investigator Patrick
3 Clones were picked in the morning and in each case inoculated 10 ml DYT. Clone 3 didnt grew fast enough. There were not enough bacteria in the eppi even after 8 ml were centrifuged. The mini-prep of clone 1 and 2 was performed according to the standrd protocol yielding the following concentrations:
Clone 1: 36,64 ng/µl
Clone 2: 7,8 ng/µl
Therefore only clone 1 was sent for sequencing (labelling: pat1, primer:VR2) and only this clone received a plasmid number: P569
No test-digestion was performed.
Because all medium was used to receive a sufficient amount of bacteria from clone 1 there was no cell suspension left to prepare a glycerol stock. Therefore again each clone was used to inoculated 10 ml DYT, following a mini-prep tomorrow.

Sequencing results:

Obviously there is something wrong with the backbone or the sequencing.

Sequencing results of VB 13.4

Investigator: Achim

We sent in another clone of the 587 KO Z34C motif to see if it carries the same mutations as the first one. If that had been the case, we could account the mutations to faulty oligos. However, sequencing showed that the second 587 KO Z34C clone is mutated as well, but in different positions. So we either recieved oligos containing various mutations, or the fill-in reaction was faulty in spite of the proofreading activity of the klenow fragment.

Because 587 KO Z34C is one of our more promising approaches, we sent another two clones from our second colony pcr/clone picking round for sequencing: 13.1 and 13.4

Contuniation: Cloning pSB1C3_Viral Brick 587KO-empty (B274/P542) into pSB1C3_001_VP2/3_Capins (B438/P514)

Investigator Patrick
Because of the sequencing results of clone 1 a mini-prep was performed only with clone 2 and 3 yielding the following concentrations:
pSB1C3_VP2/3_Capins_587KO-empty clone 2: 195 ng/µl
pSB1C3_VP2/3_Capins_587KO-empty clone 3: 224,74 ng/µl

Testdigestion:

Because somebody switched the 37°C thermoblock off i dont know the exact digestion time. Therefore i switched the thermoblock on again and waited 1 hour. I used that much DNA because the desired insert is 48 bp long. Freiburg10 0924 pat.jpg

    N-terminal VP2-Fusion & VP1 Insertion: Fusion of VP2/3_HSPG-KO

    Investigator: Hanna

    Comment: In order to target tumor cells with our AAV2 two VP2 fusion strategies were figuered out: The so called VP2-fusion and VP1 insertions. These approaches were successfully cloned and are now tested in cell culture. In order to prevent targeting of other (healthy) cells, the natural tropism of the virus needs to be knocked down. For this purpose a ViralBrick, "587-KO_empty", was designed and cloned into pSB1C3_001_VP2/3_Capins.
    Today this VP2/3_HSPG-KO sequence will be fused to the N-terminus of the Affibody, CFP/mVenus and His-Tag of both, the N-terminal fusion to VP2 and the VP1 insertion, approach.

    Cloning of the ViralBricks BAP-HSPG-ko and His-HSPG-ko into pSB1C3_VP2/3

    Investigator: Bea

    Comment: After discussing the finals constructs, we decided to clone HSPG-KO with BAP and His motifs into the N-terminal approaches which means that the plasmids pCerulean_Targeting_VP2/3 contains His and BAP ViralBricks integrated in the 587 loop, respectively. Therefore I started the first cloning step in order to obtain the fully assembled targeting construct which can be cotransfected with the plasmids containing rep and cap genes (with or wihtout HSPG-ko)


    Digestion of the constructs:

    • P604 = pSB1C3_001_587-ko_BAP
    • P606 = pSB1C3_001_587-ko_His

      • 8g of NaCl
      • 0.2g of KCl
      • 1.44g of Na2HP04 (1.69 because of the crystal water in the reagent)
      • 0.24 g of KH2PO4
    • adjust to pH 7.4
    • adjust to 1000ml
    • steril filtrate the solution


    • dissolve the following in 180ml ddH2O:
      • 6,4g of NaCl
      • 0,16g of KCl
      • 1,15g of Na2HP04 (1.69 because of the crystal water in the reagent)
      • 0,19 g of KH2PO4

    ViralBrick Sequencing results: pSB1C3_587_KO_Z34C and pSB1C3_587_KO_Z34C_Spacer

    Investigator: Achim

    Sequencing showed that the PCR reaction we designed to remove the mutations in the z34c insert were successful! Both pSB1C3_587_KO_Z34C and pSB1C3_587_KO_Z34C_Spacer are correct. We hadn't sent the 587_Z34C for sequencing because the colony PCR hadn't shown any bands. But because this construct is less important for cell culuture, we won't continue working on this construct.

    mGMK_TK30 approaches

    Investigator: Bea

    Comment: Since we are still waiting for the TK30 gene ordered at Mr.Gene we decided to take another road to produce a BioBrick compatible thymidine kinase gene. Therefore, we are cloning the mGMK_TK30 fusion construct into the pSB1C3 and after removing the PstI site (see next topic) it is ready for submitting it to the parts registry. Additionally, we are fusing the mGMK_TK30 to the composite part pSB1C3-leftITR_PROMOTER_betaglobin for testing it in cell culture with pur final super construct.

    ViralBricks BAP-ko and His-ko in VP23

    Investigator: Bea

    Comment: In order to verify the insertion of the ViralBricks BAP-ko and His-ko into the VP23 construct we digested the produced constructs with SalI and BamHI (both HF) and loaded it on a 1%a agarose gel. The constructs were used for creating the final super constructs (yay). Sequencing will verify if we subcloned the ViralBrick truly/seriously into the plasmids.


    Digestion of the constructs:

    • P660 = pSB1C3_001_VP2/3_HSPG-ko_587_BAP
    • P661 = pSB1C3_001_VP2/3_HSPG-ko_587_BAP
      • Expected size: 464bp
    • P662 = pSB1C3_001_VP2/3_HSPG-ko_587_His
    • P663 = pSB1C3_001_VP2/3_HSPG-ko_587_His
      • Expected size: 437bp
    • P525 = pSB1C3_001_VP2/3_capins
      • Expected size: 404bp


    Freiburg10 Testdigestion BiralBricks VP23 29.09.10.png


    Results:
    The detected bands correspond to the expected sizes, but we cannot distinguish between the exact sizes because they are too similar. Therefore we sent P660 and P663 for sequencing in order to confirm if the ViralBricks have been successfully subcloned in the pSB1c3_VP2/3 construct.

    Cloning VP2/3_Capins and VP2/3_HSPG-KO downstream of Middle Linker

    Investigator: Hanna

    Comment: Besides the Affibody we also want to test and characterize the DARPin for its binding properties referring to the VP2 fusion and VP1 insertion. Therefore some preliminary cloning steps have to be performed. Today the VP2/3_insCap and VP2/3_HSPG-KO sequence will be cloned downstream of the Middle Linker for the VP2 fusion.


    Practical Cloning:

      • Vector: pGA14_MiddleLinker (P301)
      • Insert: pSB1C3_VP2/3_insCap (P525) and pSB1C3_001_VP2/3_HSPG-KO (P613)
    • new vector name: pGA14_MiddleLinker_VP2/3_insCap and pGA14_MiddleLinker_VP2/3_HSPG-KO

    Test digestion of pSB1C3_001_CMV_affibody_HSPG_KO and pSB1C3_001_CMV_VP123_587_KO_Z34C

    Investigator: Anna

    Comment: 587_KO_Z34C and 587_KO_Z34C_Spacer were cloned into pSB1C3_001_CMV_VP123 as already done with the other 453 and 587 constructs (see test digestion from labday 28.09.) The test digestion looks well, nevertheless one sample out of these constructs should be sent for sequencing.
