Day 1- 2018.02.06:
- Prepare 7 plates of 60mm of diameter with 12 coverslips of 12mm.
- Treatment with Poly-D-Lysina (diluted 1/40 with PBS 1x)
- Incubate for 1h (37ºC, 5% CO2).
- Wash with PBS 1x.
- Trypsin-EDTA a plate of HEK293.
- Manual counting: 3.3×10^6cells/mL
- For every plate of 60mm: 5ml of HEK medium + the volume that correspond to 800.000 of cells: 242microL.
- Incubate at 37ºC for 24h.
Day 2- 2018.02.07:
CONCENTRATION OF PLASMID CV2 [ ]=0.7408 microg/microL.
*For every plate of 60mm of diameter –> 8 microg of DNA + 12 microL of Lipofectamine.
- CV2: 7 plates
- 75.59 microL of DNA in 1.75 mL of Optimem.
- 84 microL of Lipo in 1.75mL of Optimem.
– Incubate at RT for 5 min.
– Unify every DNA with the appropriate amount of Lipo and incubate at RT for 30 min.
– For every plate: 5ml of HEK medium and 500microL of every mix of DNA and Lipo.
– Incubate O/N at 37ºC.
Day 3- 2018.02.07:
- Fix with PFA 4%. Incubation at RT during 10min.
- Wash with PBS 1x.
- Permeation with triton 0.3%
- Wash with PBS 1x.
- Blocking solution -> 5% goat serum in PBS for 1h at RT.
- Remove the blocking solution and freeze at -80ºC.
Day 4 – 2018.02.08: Check the CV2 transfection – ICC:
- Blocking solution: 5% goat serum in PBS
- Vectashield mounting medium
Results: The samples were well transfected.
