Colony PCR of Cloning VP2 Fusion and Super constructs into pSB1C3

Investigator: Achim, Hanna

Comment: Because yesterday's cloning didn't deliver a good separartion of the expected gel bands. Nevertheless ligation and trafo was performed. In order to immediately find out, whether we received successful results a colony PCR will be performed.
Two clones were picked from each plat. In addition to that a positive (pAAV_RC) and a negative control (pSB1C3_lITR) was prepared.
Used primer: 4200 rev and Cap3500 for. Expected fragment size: 885 bp.
PCR was performed following the standard protocol.

All samples match the positive control!
To do: Mini-Prep and sequencing.

Preparation of SDS-PAGE gel (10%)

Investigator: Hanna

Comment: In order to perform a Western Blot of different virus capsids (with and without capsid-motifs), 2 10% SDS polyacrylamid gels were prepared.

Resolving gel: 15 mL

  • H2O: 5.9 mL
  • Acryl-bisacrylamide mix (30%): 5 mL
  • Tris (1.5 M, pH 8.8): 3.8 mL
  • SDS (10%): 0.15 mL
  • Ammonium persulfate (10%): 0.15 mL
  • TEMED: 0.006 mL


Stacking gel (5%): 5 mL

  • H2O: 3.4 mL
  • Acryl-bisacrylamide mix (30%): 0.83 mL
  • Tris (1.5 M, pH 6.8): 0.63 mL
  • SDS (10%): 0.05 mL
  • Ammonium persulfate (10%): 0.05 mL
  • TEMED: 0.005 mL

Colony PCR of p40_VP123_capins

Investigator: Bea

Comment: Since the first attempt did not work,and no cells grew on the plate and the same ligation was transformed again into BL-21 and a lot of clones grew on the plate, I decided to perform a colony PCR in order to check several colonies and to inoculate at the same day for a Midi-Prep.

Protocol:

  • Primer used: O162
  • Primer used: O38
Freiburg10 ColonyPCR p40vp123 1110.PNG


The PCR products were loaded on a 1% agarose gel. The results can be seen above in the gel picture:

Result: We can see two things: The cloning of p40 to VP123 worked quiet well AND the Robust PCR Kit which was used for the first time worked as well.

Cloning of lITR_CMV_betaglobin and lITR_phTERT_betaglobin into pSB1C3_CD

Investigator: Stefan

Comment: To produce another GOI for testing in cell culture, the cytosine deaminase needs to be assembled with lITR_promotor_betaglobin. In the next step hgH_rITR needs to be added.


Vector name:
pSB1C3_CD clone 1
pSB1C3_CD clone 2

Insert name:
pSB1C3_lITR_CMV_beta-globin (P729)
pSB1C3_lITR_phTERT_beta-globin (P730)

Freiburg10 cloning 111010.jpg


CD clone 1 yielded to bands around 2500 bp to 3000 bp. Since the vector was cut only using EcoRI and SpeI, it was expected to be linearized, not to be cut into two fragments this size. Therefore, this sample was discarded and cloning was continued using CD clone 2.



Gel extraction:
Was performed according to protocol.

Transformation:
Was performed according to standard protocol using BL21 cells.

Seeding HT1080 and A431 for testing different concentrations of ganciclovir by MTT-Assay

Investigator: Kerstin, Anissa

  • Seeding 4x 96-well plates: 2x HT1080 and 2x A431

Preparation of the ELISA

Investigator: Volker


The AAV particle standard that contains 3.6x10^9 viral particles was dissolved in 500µl as described in the protocol of the Progen AAV Titration ELISA and a absorption spectrum was measured. These purified and concentrated viral particles could be used for biophysical measurements, there for the possibility to detect the viral particles by absorption was interesting for us.

The Spectrum measured in the NanoDrop is the following:

T4 ligation seems to worked out. The plate contained many colonies.

147. labday 12.10.2010

Sequencing analysis: pSB1C3_mGMK_TK30 and pSB1C3_CD

Investigator: Stefan

Freiburg10 sequencing CD CFP.jpg


Test digestion of pSB1C3_CD and pSB1C3_CD_SDM-PstI_new

Investigator: Stefan

Comment: Nachricht von Stefan an Stefan: bitte ergänzen!

Comment: Sequencing results revealed that there is CFP rather than CD in P819. In order to verify this and exclude the possibility that the wrong plasmid was sent for sequencing test digestions were performed. Additionally the original vector at which the SDM to remove the PstI was performed was digested as well to verify its insert.

Components digest 1 / µl digest 2 / µl
DNA 1 7
Buffer 4 1 1
BSA (10x) 1 1
Enzyme I SpeI 0,3 PstI 0,3
Enzyme II XbaI 0,3 XbaI 0,3
H2O 6,4 0,4
Total volume 10 10

Comment: Using these digestion approaches, it was expected for CFP to deliver always bands at ~750 bp. For the CD it was expected to show bands at 90 bp, 1200 bp and 2000 bp if the CD still contains the PstI restictiton site, 1300 bp and 2000 bp if it was removed.

Gel:
0,5g agarose, 50 ml TAE (1%), 3 µl GELRED, 115 Volt, running time ~50 minutes

Freiburg10 test digestion 121010 1.jpg

Comment: As it can be seen, P819 does contain CFP, therefore a mistakenly sequenced plasmid can be excluded. Also it can be seen that P690 contains the CD. Therefore an additonal SDM of P690 to remove the PstI restriction site is necessary.

qPCR of virus stock: P816/ TKGMk-Standard; R/C: P468 from 5.10. (VLP harvested by Adrian)

Investigator: Achim

Protocol for quantitative real-time PCR of virus particles

Date: 12.10.

Achim

Virus Stock: A.F.; P816; TKGMK-Standard; R/C: P468; 5.10; consists of supernatant from pelleted cell fragments.

Following the Protocol used by (Rohr et al., 2002).

I digested 5 µl virus dilution with 7,5 µl DNAse I (7,5 units) and 25 µl 50 mM MgCl2 (end concentration 25 mM) in a final volume of 50 µl at 37°C for 30 min.

è DNAse should be heat inactivated at 65°C for 10 min. I forgot that step. The enzyme should however be inactivated in the initial denaturation step.

I prepared the following PCR reactions:

Results:

Freiburg10 2010-10-12 qPCR Auswertung.PNG

è Both negative controls containing primers were contaminated with DNA.

è Negative controls containing only H2O were negative.

è Values for plasmids/reaction vary; from 1 – 100 for the same virus stock

è Dilution of the virus solution: 1:10; 2µl PCR sample: 3.2 * 10^5 virus particles/ml

è Because of the contaminated negative controls and the high deviation, I will repeat the experiment tomorrow to verify the results.

Cloning sr39 into mGMK_TK30

Investigator: Bea

Comment: We do not only want to submit the tk30, a mutant version of the thymidine kinase, but as well another mutant protein which is named sr39. SR39 seems to have a better activity than the tk30 without being fused to the guanylate kinase (mgmk), but the sr39 also works quite well as a fusion protein. We ordered one part of the sr39 and we are now subcloning it into the mgmnk_tk30 construct in order to obtain mgmk_sr39.

Protocol:

Freiburg10 SR39 into mGMK tk30 12.10.PNG


The digested fragments were loaded on a 1.2% agarose gel. The results can be seen above in the gel picture: I cut out the small visible band in the right lane, and the upper intensive band of the left lane.

Result:

Freiburg10 Digest sr39 and mGMK tk30.png


After gel extraction has been performed, I ligated the two fragments and transformed BL-21 cells, plated them on cm agar plates and incubated them over night at 37°C.

Concentration of virus stock for Western Blot analysis

Investigator: Hanna

For the first Western Blot try, we investigate whether is is enough to concentrate the virus stock (from cell supernatant) and then to simply load it onto a SDS-PAGE gel and perfom immuno-staining.
For this purpose 8 mL virus stock (pHelper, pAAV_RC, GOI=YFP) were concentrated via amicon filtration.

  • First, amicon filter was washed with 4 mL PBS.
  • Then 4 mL virus stock was loaded onto the filter and centrifuged at 3000 rpm for 15 minutes.
  • Flow-through was discarded and additional virus stock was loaded, centrifuged at 3000 rpm for 25 minutes.
  • Flow-through was discarded, remaining solution was re-suspended and additional virus stock was added. Amicon filter was centrifuged at 3000 rpm for 50 minutes.
  • Flow-through was discarded. Residual protein solution: 500 µL. Filter was washed with 3 mL PBS, centrifuging 35 minutes two times.
  • 2 x 40 µL protein solution (16x) was taken and mixed with Laemmli buffer and stored over night @ 4°C.


To do: SDS-PAGE and Western Blot tomorrow.
Perfomance of another try by harvesting viruses of the cell pellet with RIPA buffer & freeze/ thaw.
Western Blot of unmodified, and modified capsids (N-terminal fusion and VP1 insertion with CFP ref. mVenus) --> size shift should be detectable.

Comment: P822 and P823 smear a lot, therefore evaluation is difficult. Another test digestion would be reasonable.
P824 contains hgH_rITR, therefore it will be discarded. P825 looks well and was sent for sequencing.
P830 and P831 look well and will be sent for sequencing tomorrow.

SDS Page of unmodified AAV2 capsids

Investigator: Hanna

Comment: Yesterday a 8x concentration of AAV2 supernatant-stock was performed. 10 µL Laemmli-buffer was added to 40 µL AAV stock (8x) and stored over night at 4°C.
Today a SDS-PAGE of these samples will be performed.

Samples were incubated for 10 minutes at 95°C for denaturation.

Loading plan:

5 µL PageRuler Prestained Protein Ladder 10 µL Sample 15 µL Sample 25 µL Sample


After running front reached the end of the gel, PAGE was stopped.

Western Blot:
Three layers of transfer buffer soaked whatman paper were placed onto the blotter. A polyvinylidene difluoride membrane was activated by methanol (5 seconds) and then incubated for 5 minutes in transfer buffer. Membrane was then placed onto the whatman paper, gel was carefully layed on top. Air bubbles were removed, ensuring elictricity flow. After coverage by 3 further layers of whatman, blotting was performed at 200 mA for 1 hour.

Blocking:
In order to minimize nonspecific antibody interactions, membrane was incubated in blocking buffer (TBS (pH 7.5), 5% milk powder) for one hour, shaking.

Primary antibody incubation:
A 1:10 dilution of the B1 antibody in TBS + 1% milk was prepared. Membrane was incubated in 50 mL falcon over night at 4°C, rotating.

Sequencing analysis: pSB1C3_leftITR_pCMV_betaglobin_mGMK_TK30_hgH_rITR (P825)

Investigator: Stefan

For sequencing the following primers were used_

  • qPCR primer CMV for (O20)
  • GOI primer for (O30)
  • seq. primer TK GMK for (O23)
  • TK30 SDM Pst for (O191)

Sequencing comfirmed that the pysical sequence fits our theoretical. Next step will be to remove the remaining PstI restriction site within TK30.

Repetition of cloning of Rep into Rep78

Investigator: Kira
Comment: The last 2 approaches to digest Rep78 and to clone failed because Rep78 was almost gone after PCR purification and was not detectable on the gel, even if I used the double amount of DNA. Thus, new over night culture was grown in order to perform the experiment again

Regarding the activity conditions of the enzymes, digestion was performed in 2 steps.

Continuation of Western Blot of unmodified AAV2 capsids

Investigator: Hanna

Comment: Yesterday, SDS PAGE, Western Blot and primary B1 mouse antibody incubation was performed.
Today, secondary antibody incubation and ECL analysis will be done.


Because of these dissatisfying results SDS PAGE will be repeated. Instead of performing Western Blot, gel wioll be stained by Coomassie in order to optimize SDS-PAGE conditions.

As usual the PSB1C3 bands indicate a higher bp amount than they actually got.
The gelextraction ...


... and following ligation (2 µl Insert, 6 µl vector, 1 µl T4 DNA Ligase, 1 µl T4 DNA Ligase Buffer, 40 minutes, RT) were performed according to the standard protocol. After the transformation (with BL21) the cells were plated and put into the 37°C room.
