Protocol for CHO-S Cell Transfection by FuGENE HD

  1. Cell plating

    Cells for transfection were grown in 15 mL CD-CHO medium (Gibco®) in 50 ml tubes on rotator at 110 RPM. The rotor was placed at 40° angle. Cells for transfection were harvested at approximately 1,000,000 cells / ml. Cells were seeded in 96-well flat bottom non-tissue culture plate just before transfection with the density 50,000 cells per well in 100 μl growth medium.

  2. Complex preparation (per 20 wells)

    Tissue culture 96-round bottom well plates were used for complex preparation:

    1. Prepare 0.0125 μg/μl gWIZ™ GFP DNA solution in sterile deionized water.
    2. Add 9 μl of FuGENE®HD to 160μl of DNA solution.
    3. Mix carefully by pipetting (10-15 times).
    4. Incubation of complex is not necessary.
    5. Add 8 μl of complex to the cells, per well and mix thoroughly.

    Optimal FuGENE®HD/DNA ratio may vary in range 0.3μl/0.1μg to 0.5μl/0.1μg.

  3. Incubation

    Place the cells into CO2 incubator with orbital shaker at 110 RPM for 72 hours.

  4. Detection of GFP expression

    Monitor the GFP expression under fluorescent microscope or by flow cytometery.
