Protocol for transfection of AGS (ATCC®: CRL-1739™) Cells by FuGENE HD in 96 well plates.

  1. Cell plating

    AGS (Human Gastric Adenocarcinoma) cells were seeded from 90-100% confluent culture the day before transfection with the density 5,000 cells/well in 100 μl complete growth medium (F-12K + 10% Fetal Bovine Serum).

  2. Complex preparation (per 20 wells)

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

    1. Prepare 0.02μg/μl pCMVβ DNA solution in OptiMEM® or sterile deionized water.
    2. Add 6 μl of reagent to 100 μl of DNA solution.
    3. Mix carefully by pipetting (15 times).
    4. Incubate 10 min at room temperature.
    5. Add 5 μl of complex per well to the cells, and mix thoroughly.
  3. Incubation

    Transfected cells were incubated in CO2 incubator for 72 hours.

  4. Detection of β-gal expression
    1. Remove the medium from the well and wash the cells once with 100μl per well PBS.
    2. Fix the cells in the well with 50μl solution of 4% formaldehyde in PBS for 5min at room temperature.
    3. Wash each well twice with 100μl PBS.
    4. Add 50μl per well of substrate/stain solution and incubate the plate overnight at 37°C.
    5. Observe the cells under microscope and evaluate the proportion of blue (β-gal-positive) cells.
