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.

NIH 3T3 cells were transduced twice with MuLV IRES EGFP for 6h. Picture was made after 48 h of incubation at 37°C.

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.

Description of Image

NIH 3T3 cells were transduced twice with MuLV IRES EGFP for 6h. Picture was made after 48 h of incubation at 37°C (2014-05-28-nih-3t3-100mm-mulv-pmig-ires-egfp-transd-48h)

  • 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)
