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

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.

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.

Ligation with T4 DNA ligase: 1 µl buffer (10x), 1 µl T4 DNA ligase, 7 µl Vector, 1 µl Insert, 70 minutes.

The transformation with XL1B was performed according to the standard protocol and plated: pSB1C3_VP2/3_Capins_587KO-empty

Cellculture: Serum-free cells

Investigator Patrick
We want our virus production to be serum-free to simplify the following purification.

PCR of VB constructs to remove mutations

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

Sequencing results: pCerulean_Zegfr:1907_VP2/3

Investigator: Hanna

Sequencing results revealed that VP2/3 (unmodified!) was successfully fused to the Affibody (without linker).
Next step: Fusion of VP2/3-HSPG-KO to the C-terminus of the Affibody.

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.

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.

Mini-Prep and Test-digestion of VP1 insertion and VP2 fusion HSPG-KO approaches

Investigator: Hanna

Comments: Yesterday, 2 clones of each construct were picked. Today mini-prep and test digestion will be performed of one of each approach - the other clones will be spinned down and stored at -20°C - waiting for test digestion and sequencing results.

Mini-Prep was performed, following the standard protocol.
