I guess that the pSB1C3_001_CMV did NOT work since the control with BLA looks nearly the same. We should repeat the experiment by cloning the CMV promoter into another vector. I would recommend it because we have a lot of constructs which we should fuse to the CMV promoter and in order to avoid the three-fragment ligation.

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:

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

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 :
Freiburg10 2 10 TestD.png

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.

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

You can either find these constructs in my workingfolder "DARPin" or the pGA14_MiddleLinker in the "Linker-Folder" and the VP2/3_insCap in many workingfolders!!!! You could have also digest the construct with EcoRI and SpeI... then you would expect a 2 and a 2.3 kb fragment... menas: you have to run the gel at least 1 hour - but it works (see the previous test digestion of the MiddleLinker_VP2/3_insCap construct!!!!).

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.
Both samples show correctly sized bands. The negative control ran further than expected, it should be located at 4500 bp.

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)


Stock 2 "standard" virus (4 wells from a 6 well plate)

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:

  1. DMEM as negative control
  2. resuspended Pellet with mVenus-fusioned viral capsids
  3. resuspended Pellet with "standard virus"
  4. supernatant with mVenus-fusioned viral capsids
  5. 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:

Freiburg10 mVenus VP fusion fluorescence centrifugation experiment graph.jpg


Freiburg10 mVenus VP fusion fluorescence centrifugation experiment 526nm.jpg


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:

  1. control vector from 15.9, 750.000 cells, 3.3 µg approach
  2. P25 R/C= 326 pTERT_mVenus
  3. P26 pAAV_RC_RepCapIns_SDMKpnI clone 1 P431 pTERT_mVenus
  4. 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:

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

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.

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 the cause of this cellular mass mortality.
