Sequencing results of pCerulean_Zegfr:1907_MiddleLinker_VP2/3_HSPG-KO
Investigator: Hanna
Comment: All N-terminal fusion approaches with VP2/3_HSPG-KO revealed positive results except of pCerulean_Zegfr:1907_MiddleLinker_VP2/3_HSPG-KO. Another clone was picked, preped, test digested and sent for sequencing.
Conclusion: Sequencing results revealed positive results.
Picking clones of pGA14_MiddleLinker_VP2/3_insCap and pGA14_MiddleLinker_VP2/3_HSPG-KO
Investigator: Hanna
Unfortunately there grew a bacteria lawn over night - it was hardly not possible to pick clones. Nevertheless I tried and picked 2 clones of pGA14_MiddleLinker_VP2/3_insCap and pGA14_MiddleLinker_VP2/3_HSPG-KO.
To do: Mini-Prep and test digestion.
Sequencing results of pSB1C3_001_VP2/3_587-KO_BAP and pSB1C3_001_VP2/3_587-KO_6xHis
Investigator: Hanna
Comment: For the creation of our super constructs, the His-Tag and the BAP motif need to be cloned into VP2/3 for N-terminal fusion to VP2. Sequencing results showed that the 6xHis and BAP motif was not cloned into VP2/3_insCap.
 |

To do: Clone 587-KO_6xHis and 587-KO_BAP into pSB1C3_001_VP2/3_insCap 1. via digestion of inserts and 2. via hybridization of referring oligos - digestion of vector with 800-900 ng.
Impressions of transfection of AAV293 with pCerulean_VP1up_NLS_mVenus_VP2/3
Investigator: Adrian
Yesterday AAV293 cells were transfected with pCerulean_VP1up_NLS_mVenus_VP2/3 and GMK-TK30 as gene of interest. Today, nuclear localization of the produced mVenus_VP2/3 fusion protein was visible and can be nicely seen in the following pictures:
Conclusion: The VP2/3 fusion particle was transcribed and translated AND was transported back into the nucleus in order to be packaged by the ITR-flanked gene of interest.

Repetition of the approach of subcloning the ViralBricks HSPG-ko BAP and His into VP2/3 with different strategies
Investigator: Bea
Comment: Unfortunately, the last experiment revealed that subcloning of the two ViralBricks did not work out which was shown by the sequencing results. Therefore we need to repeat the approach of subcloning the ViralBricks into the pSB1C3_VP2/3 which than can be used for fusing it to the n-terminal targeting approaches. Two different strategies will be carried out which means that we are digesting the pSB1C3_Viralbricks AND hybridize the oligos (BAP and His) in order to obtain some positive results.
The vector and ViralBricks were digested with BamHi and PvuII. The vector was dephosphorylated following the standard protocol.
The vector was loaded on a 1% agarose gel before dephosphorylation was conducted. The results can be seen above in the gel picture:
Result:
The ligation was performed over night at 18°C with T4-ligase.
BioBrick Assembly of CD and mCherry
Investigator: Bea
Comment: We decided to choose some additional GOI´s for the vectorplasmid so the "new" GOI´s need to be fused to the leftITR_Promoter_betaglobin constructs. Since only one clone grew on the plate prepared by Kira where she fused the CD (cytosine deaminase) to the above mentioned construct I am going to repeat it aswell.
Digestion of the constructs:
- P689 = pSB1C3_CD
- P626 = iGEM_mCherry
- P434 = pSB1C3_leftITR_CMV_betaglobin
- P434 = pSB1C3_leftITR_phTERT_betaglobin
- P525 = pSB1C3_VP2/capins
Loading plan:
P689 (pSB1C3_CD) P626 (iGEM mCherry) P434 (pSB1C3_lITR_CMV_ß-globin) P437 (pSB1C3_lITR_phTERT_ß-globin)
Results:
After gel extraction has been performed, the ligation was carried out.
Ligation:
The ligation mix was transformed into XL1-Blue cells and plated on agar plates containing chloramphenicol.
Next steps:
Picking clones and perform Mini-Prep. After the Mini-Preps have been performed this construct needs to be sequenced and tested in cell culture.
comment: just one clone? uhhhh, when did you take out the plate? i put it at around 1 am..maybe they need a while to grow, no? (Kira)
Yep, I found another clone ;-) But the two look pretty good. I took them out today in the afternoon - I guess that is enough time! But if you want I can put them back into the 37° C room??! (Bea)
Mini Prep and test digestion of pGa14_MiddleLinker_VP2/3_HSPG-KO
Investigator: Hanna
Comment: In order to fuse the DARPin to the N-terminus of VP2/3_insCap and VP2/3_HSPG-KO, these motifs need to be fused to the Middle Linker (performed on 30.9.2010). In order to be able to immediately continue with cloning, BL21 cells were transformed and clones were picked in the noon. Now, the DNA needs to be preped and test digested in order to perform a 3-fragment-ligation with the DARPin and the pSB1C3_001_CMV plasmid. Unfortunately the cells of the VP2/3_insCap construct grew not densely enough. Therefore two new clones were picked from the plate and were inoculated in 10 mL LB medium. The other construct (pGa14_MiddleLinker_VP2/3_HSPG-KO) was preped and test digested.
TEST DIGESTION:
For both clones:
- DNA: 4 µL
- Buffer 4: 1 µL
- BSA: 1 µL
- EcoRI: 0.5 µL
- PstI: 0.5 µL
- H2O: 3 µL
Incubation: 1 hour.
Agarose gel: 0.8 %, 115 Volt, 1 hour.
Comment: The choice of these restriction enzymes was not clever, because if cloning didn't work, I expect one band at 2379 bp (the insert should hardly be seen) - if it worked one band at 2379 bp and a second at 2005 bp. Fortunately the bands could be separated ans revealed positive results for both clones :
Next steps:
- Mini-Prep and test digestion of pGa14_MiddleLinker_VP2/3_ins Cap.
- 3 fragment ligation of MiddleLinker_VP2/3_ins Cap or MiddleLinker_VP2/3_HSPG-KO + DARPin + pSB1C3_001_CMV backbone.
Sequencing analysis of HSPG-ko in several IRCK constructs

- pSB1C3_Darpin clone2 c=205.6 ng/µl
- pGA14_MiddleLinker_VP2/3_inscap clone 1 c=147.5 ng/µl
- pGA14_MiddleLinker_VP2/3_inscap clone 2 c=121.0 ng/µl
Test-digestion:
| Components | pSB1C3_Darpin clone1/2 |
| DNA | 1,5 µl |
| BSA (10x) | 1 µl |
| Buffer no. 4 | 1 µl |
| Enzyme 1 XbaI | 0,4 µl |
| Enzyme 2 AgeI | 0,4 µl |
| H2O | 5,7 µl |
| Total volume | 10 |
Hanna wrote that a 3rd enzyme is need for the test digestion of pGA14_MiddleLinker_VP2/3_inscap but I couln't find any sequence of pGA14_MiddleLinker_VP2/3_inscap or pGA14
Test digestion of pGA14_MiddleLinker_VP2/3_inscap
Investigator: Achim
- pGA14_MiddleLinker_VP2/3_inscap clone 1 c=147.5 ng/µl (P698)
- pGA14_MiddleLinker_VP2/3_inscap clone 2 c=121.0 ng/µl (P699)
- Control: pGA14_MiddleLinker (P301)
- Digestion with EcoRI & SalI; should yield two bands of 3400 & 1000 bp. The negative control should only be cut once.

Analysis of viral harvest via spectrometer
Investigator: Adrian, Patrick
The motivation: We want to figure out if it is possible to purify our viral stocks via centrifugation with 10.000 g and/or 20.000 g. In theory/ according to the literature the viral particles should be in the cells and attached to the HSPGs at the cellular surfaces.
The plan: Two different viral stocks were prepared:
Stock 1 with VP2-mVenus-fusion-Capsid loaded with TKGMK (4 wells from a 6 well plate)
- R/C 1: 50% pCerulean_VP1up_NLS_mVenus_Vp2/3 P501
- R/C 2: 50% Rep/Cap2: P449 pAAV_RC_4fachmut_VP1-ko:
- GOI: TKGMK: P82.b
- pHelper
Stock 2 "standard" virus (4 wells from a 6 well plate)
- R/C 1 P486
- GOI: TKGMK: P82.b
- pHelper
These two stocks got harvested according to standard protocol (scratching cells, transfer them in to 15 ml falcons, resuling 12ml solution total). After centrifugation (10 min 200g), the supernatant got transferred into two new 15 ml falcons and the pellets were resuspended with 10 ml DMEM Medium. The Stocks got freezed thawed two times so finally there were:
- DMEM as negative control
- resuspended Pellet with mVenus-fusioned viral capsids
- resuspended Pellet with "standard virus"
- supernatant with mVenus-fusioned viral capsids
- supernatant with "standard virus"
The fluorescence of each stock was measured via spectrometer. After that, stocks 2 and 4 were centrifugated 10min with 10.000 g followed by an other fluorescence measuring. Finally the stocks got spin down with 20.000 g for 10 min
The results:
The conclusions:
The highest amount of fluorescence was measured in the supernatant, the individual centrifugation steps had no decrease in fluorescence as consequence!
Keep in mind, without further investigation it is not valid to say that we can purify our stocks via 10-20.000 g centrifugation steps, because we dont know if the viral capsids are still intact! The FACS analysis are not sufficient enough to make a decision, because our last samples had YFP as GOI (=> so efficient cell sorting was not possible). We need to do qPCRs to make a valid evidence.
200µl-Transduction for testing the pTERT-promoter
Investigator: Adrian, Patrick
We transduced A431, HT1080 and AAV293 cells with 4 different viral stocks:
- control vector from 15.9, 750.000 cells, 3.3 µg approach
- P25 R/C= 326 pTERT_mVenus
- P26 pAAV_RC_RepCapIns_SDMKpnI clone 1 P431 pTERT_mVenus
- His-linker-fusion
CRUCIAL: There was not enough viral stock: so the whole Transduction was performed with 200µl instead of 1000µl
There are 45 samples to FACS on monday 4.10. Tripple values for each stock of each cell lines.
Transfection
Investigators: Adrian, Patrick
Transfection followed standard protocol (3.3 µg of each plasmid, 1 ml 0.3M CaCl2 and 1 ml of 2xHBS buffer PH 11.12) but with 20 min incubation time (Ca-DNA-2xHBS)
following stocks:
- mVenus standard stock 10 x cm R/C: P4682 plates
- TKGMK stock 10 x cm2 plates R/C: P468
- viral particles with GOI (mVenus) missing HGH one 6well plate
- viral particles with GOI (mVenus) missing beta globin one 6well plate
- viral particles with R/C missing HSPG binding motif (P687) one 6well plate
- viral particles with new standard R/C (P668) one 6well plate

Proceeding with the approach of subcloning the ViralBricks HSPG-ko BAP and His into VP2/3 with different strategies
Investigator: Bea
Comment: Ligation was carried out over night and transformation will be performed today.
Since the digested vector was not sufficient for all four ligation I decided to perform the ligation only with the hybridized oligos 587-ko His and the digested Viralbricks 587-HSPG-ko His and BAP. If the digested BAP insert reverals no positive results, the hybrizied oligos for BAP can be used for another approach. The transformation was carried out in
- BL-21 cells
- and plated on agar plastes containing chloramphenicol

Assembly of pSB1C3_CMV_DARPin_VP2/3_insCap and pSB1C3_CMV_DARPin_VP2/3_HSPG-KO
Investigators: Hanna
Comment: We also want to test the DARPin_E01 for the N-terminal fusion approaches. Today a 3 fragment ligation will be performed in order to complete the VP2 fusion constructs with the DARPin.
Because 2 test digestions showed that the fusion of the DARPin to VP1up_NLS didn't work as ecpected (insert is too large) this has to be repeated before also the VP1 insertion with the DARPin can be completed.

Site-directed mutagenesis in pSB1C3_mGMK_TK30 construct
Investigator: Bea
Comment: Since we are still waiting for the ordered TK30, idea was to mutate the PstI site in the TK30 region. After mutating the PstI it is ready for submitting. Addtionally the ordered and received sr3ß can be subcloned.
Protocol using the QuickChange Ligthning Kit from Stratagene:
https://2010.igem.org/Image:Freiburg10_SDM_PstI_TK30_05_10.tif
The follwoing PCR was used:
- 95 °C 2'
- 95 °C 20"
- 60 °C 1'
- 68 °C 2'
- Goto 2 repeat 17
- 68 °C 5'
After the PCR program was conducted, I added 1 µL of DpnI provided with the Kit to each sample and incubated it for 10 minutes.
For transformation XL-10 Gold cells with 2µL beta-mercaptoethanol have been used and plated on agar plates containing chloramphenicol.
Cellculture: Bad news
Something happened to our virus-production cell line AAV293.
Nearly all AAV293 cells are dead.
The whole Loop-Insertion Transfection from 3.10 is lost, our actual culture flasks aswell. We dont know exactly the cause of this cellular mass mortality. Maybe someting is wrong with the new FCS-stocks.
Repetition of pCerulean_VP1up_NLS_DARPin
Investigators: Achim
- The Test Digestion (1.10.) of the last attempts clones didn't look convincing. We sent clone 1 for sequencing yesterday, but we didn't recieve any results yet. That's why I decided to repeat the experiment today, in case results are negative.
- Details: See first run from 28.9.

Harvest of viral stocks
Investigators:
Number of viral stocks: 4
- mVenus standard stock 10 x cm R/C: P4682 plates => Harvest in 2 50 ml Falcons, four times freeze thaw centrifugation step with 2500g for 10 min
- TKGMK stock 10 x cm2 plates R/C: P468 => Harvest in 2 50 ml Falcons, four times freeze thaw centrifugation step with 2500g for 10 min
- viral particles with GOI (mVenus) missing HGH one 6well plate => Harvest in 1 50 ml Falcon, four times freeze thaw centrifugation step with 2500g for 10 min
- viral particles with GOI (mVenus) missing beta globin one 6well plate => Harvest in 1 50 ml Falcon, four times freeze thaw centrifugation step with 2500g for 10 min
- viral particles with R/C missing HSPG binding motif one 6well plate => Harvest in 1 50 ml Falcon, four times freeze thaw centrifugation step with 2500g for 10 min
- viral particles with new standard R/C (intact HSPG binding motif) one 6well plate => Harvest in 1 50 ml Falcon, four times freeze thaw centrifugation step with 2500g for 10 min
Motivation:
The two new standard vectors are from now on called Control Vectors, to get valide data. The TKGMK Stock will be used for the MTT-ASSAY.

Sequence analysis of pSB1C3_CD
Investigator: Bea
Comment: After test digestion revealed positive results we sent one clone for sequencing.
<b<Results</b>:
- Prefix looks well. Alle restriction sites can be found in the prefix RFC25.
- Suffixlooks well. Alle restriction sites can be found in the suffix RFC25.
- BUT: There seems to be a PstI recognition site within the sequence. Therefore the site-directed mutagenesis needs to be repeated.
