Transfection/ Virus production
For virus production Phoenix cells (producer cell line) were splitted (well separated) on 100mm plates. At 70% cell density cells were transfected using polyethylenimine.
- remove medium and refill with 5 ml new completed growth medium (DMEM)
- 600 µl transfection mastermix was prepared (8 µg pMIG IRES EGFP, 24 µl PEI, rest OptiMEM)
- mastermix was incubated 15 min and carefully drop on the plates
Plates were incubated at 37°C. The supernatant after 24 was removed and refilled with 5 ml new DMEM, the supernatant was collected after 48 h (refilled with 5 ml DMEM) as well as 72 h.

Transduction mouse cells
NIH 3T3 cells (60% density) were transduced with MuLV IRES EGFP.
- 500 µl of supernatant was removed
- 1 µl Polybrene was added (10mg/ml)
- 500 µl virus supernatant was added (sterile filtered)
- incubation at 37°C for 6h
- cell supernatant was replaced with fresh DMEM
- transduction was repeated once
Pictures could be made after 48 h of incubation.

Thawing of eukaryotic cells
New Phoenix cell stocks were thawed:
- cryotube was thawed at 37°C water bath until almost defrosted
- stock was filled in 9 ml warm DMEM and centrifuged at 900 rpm for 2 min
- medium was removed and refilled with 10 ml warm DMEM
- cells were seeded on 100 mm plate
Testing optimal cell density of mouse fibroblasts
NIH 3T3 have a really fast growth so that we tested the optimal cell number for seeding NIH 3T3 for having around 60% cell density on the next day. NIH 3T3 cells grow very fast; therefore we have tested the optimal seeding cell number to obtain 60% cell density on the next day.
- incubation for 24 h at 37°C
--> optimal cell number is 1 – 1.5x10^5 cells per well ( = 0.5 – 0.75 cells/ml)

Transfection/ Virus production
Transfection of Phoenix cells (70% density) with pMIG IRES EGFP (protocol: 2014/05/21) (2 x 100mm plate)
