This subpage is for cellculture, the structure of each experiment is following:
Date of first action, title of the experiment
The motivation
This short introduction provides an inside into our thoughts for this experiment.
The plan
In this section, the design of the experiment is explained.
The results
Interpretation and discussion of our results.
11.8.2010 Transduction of HT1080 with no AAV, AAV without GOI and AAV with 10µg -> FACS
The motivation: In the past, the percentage of living cells in FACS was very low (~ 70%) so we want to check if the AAV-induced stress is responsible for cellular death, or the detaching procedure (trypsin and mechanical stress).
The plan
Plate I
| control, no cells | no GOI 150µl | 10µg 500µl |
| control, no virus | no GOI 300µl | 10µg 750µl |
Plate II
| control, no cells | no GOI 150µl | 10µg 500µl |
| control, no virus | no GOI 300µl | 10µg 750µl |
Plate III
| control, no cells | no GOI 150µl | 10µg 500µl |
| control, no virus | no virus | 10µg 750µl |
The results
ADD FACS DATA
The YFP expression is still quite low. This was kind of anticipated, the success in this experiment is the fact, that the amount of living cells is at a very high level! (~90%). The conclusion: Detach the cells fast! Use PBS which is not at 37°C (the PBS was 25min in the water bath), transfer the cells fast on ice after detaching!
The next steps are:
- Is it possible, that freeze/thaw circles reduce the transduction efficiency?
- Why is the YFP-expression that low? (~28-30%)
12.8 Virus production, seeding A431 cells
The motivation
In first place we want to create new stock of AAV without GOI, the next viral stock is with correct TK/GMK, the last stocks are with different YFP-amounts to check if the amount of GOI is a critical step for transduction effency (transgene expression).
The plan
See transduction protocoll for further information, the final cantrifugation step was done with 2000 g 5 min.
The results
Ten viral stocks with 3 ml each were prepared.
| Plate | pAAV_RC/µg | pHelper/µg | GOI/µg |
| 1 | 3,3 | 3,3 | no GOI |
| 2 | 6,6 | 3,3 | no GOI |
| 3 | 3,3 | 3,3 | 3,3 TK_GMK clone1 |
| 4 | 3,3 | 3,3 | 3,3 TK_GMK clone1 |
| 5 | 3,3 | 3,3 | 3,3 TK_GMK clone2 |
| 6 | 3,3 | 3,3 | 3,3 YFP |
| 7 | 3,3 | 3,3 | 10 YFP |
| 8 | 3,3 | 3,3 | 20 YFP |
| 9 | 3,3 | 3,3 | 40 YFP |
| 10 | 3,3 | 3,3 | 60 YFP |
The nomenclature of the plasmids is wrong, the date is 12.8. not 13.8

16.8: The fluorescence was quite low (~ 5%)in nearly every well! The 40µg YFP wells were the only exception.
The conclusions
The incubation step of CaCl2 seems to be crucial! The next transfection protocol is with a 30 min incubation on ice step!
Seeding HEK293 for transfection at monday 16.8
The motivation
Which confluence of HEK293 cells is optimal for AAV production?
The plan
We seed different amounts of cells, and check the highest titer.
| Plate | amount of cells |
| 1 | 100 000 |
| 2 | 200 000 |
| 3 | 400 000 |
| 4 | 500 000 |
| 5 | 800 000 |
| 6 | 1 000 000 |
| 7 | 1 200 000 |
| 8 | 1 500 000 |
| 9 | 1 750 000 |
| 10 | 1 750 000 not sure |
The results
Fluorescence microscopy of transduction at 14.8 transfection of plates from 13.8
Working steps:
- Remove the three plasmids to be co-transfected (the recombinant pAAV expression plasmid or control plasmid, pAAV-RC, and pHelper) from storage at –20°C.
- Pipet XXX µg of each of the three plasmid DNA solutions into an eppi. The standart protocol is: 10 µg per plasmid, experiment data showed that the amounts (3,3 µg, 6,6 µg and 10 µg per plasmid) showed similar results
- Fill up to 300 µl with sterile water. Add 300µl of 0.5 M CaCl2 and mix gentlyIncubation step 45 min on ice !!!!!!
- Pipet 600 µl ml of 2 × HBS into a 15-ml falcon.
- Vortex the falcon (with the 2x HBS) gently!!!! while pipetting the DNA/CaCl2 solution dropwise into the falcon (use the Pipetus).
- Apply the DNA/CaCl2/HBS suspension to the plate of cells in a dropwise fashion(experimental data shows that resuspending-fashion is better for high titer), swirling gently to distribute the DNA suspension evenly in the medium.
- Return the tissue culture plate to the 37°C room for 6 hours.
- At the end of the incubation period, remove the medium from the plate and wash cells with warm PBS, replace it with 10 ml of fresh DMEM growth medium.This is a crucial step! The transfection-stress kills nearly all cells if theres no medium change
- Return the plate to the 37°C incubator for an additional 72 hours.

we want to check the optimal ganciclovir concentration, we use the TK/GMK Stocks (10 µg from each plasmid) from 24.8 with Buffer pH 7,10 and the pH12 stock.
The plan
| Days | 3.9 | 4.9 | 5.9 | 6.9 |
|---|---|---|---|---|
| Action | seeding HT | Transduction | - | FACS |
We want to use five different ganciclovir concentrations (the concentrations are absolute to the volume in the wells):
- 48.5µM
- 97 µM
- 0.485 mM
- 0.97 mM
- 4.85 mM
the results
22.9 Transfection with Volkers R/C constructs
The motivation
We want to check if these R/C still work!
The plan
| Days | 20.9 | 21.9 | 22.9 | 23.9 | 24.9 | 25.9 | 26.9 | 27.9 | 28.9 |
|---|---|---|---|---|---|---|---|---|---|
| Action | seeding AAV293: 4*6wells | - | Transfection: 4 constructs | - | - | Seeding HT | Harvest + Transduction | - | FACS |
The results on the 23.9 it was shure that something went wrong with the nomenclature, so this approach is definitely not working => threwn away!
22.9 Testing of Hannas 6 VP-constructs with different compositions (10%, 25%, 50% and 75% fractions) with a VP2-knockout construct
The motivation
Test the 18 constructs for functionality on A431 and HT1080 cells.
The plan
| Days | 20.9 | 21.9 | 22.9 | 23.9 | 24.9 | 25.9 | 26.9 | 27.9 | 28.9 |

The results
22.9 Testing pTERT_mVENUS in R/C P326 and P431
The motivation
We want to check if the pTERT-promoter is realiable for tumor specific gene expression.
