The General Guidelines for Cell Culture

by Yang Wenting on June 4, 2011

Before a cell line is put into culture, several factors should be considered

  • Are the cells coming from established, well-defined lines? Is the species known?
  • Are the nutrient and CO2 requirements known?
  • Are the growth patterns known?
  • Has mycoplasma testing been done?
  • Will the cells be cultured in plates, flasks, bioreactors, etc?
  • What volume/number of cells will be required

Passage cells (10 cm-dishes)

  1. Pour out media from cell culture dish.
  2. Wash it with Hanks 5 ml per dish.
  3. Tilt around then pour out in order to removal the old media, especially blood serum which may prevent the effect of trypsin.
  4. Add 3 ml of Trypsin / EDTA to each dish. Then incubate it in the incubator for about 3-5 minutes.
  5. Add 10% or 20%-complete media 4 ml per dish and tilt.
  6. Scrape (most of the small cells are already released; proliferative cells lift up easy, differentiative cells are more adherent).
  7. Place contents into a15 ml Falcon tube.
  8. Spin it at 1000 RPM for 5 min.
  9. Dump off supernatant.
  10. Add 2 ml enough media per dish.
  11. Each dish should have 8(or 10) ml of completed media, add cells (They are spread by 1 : 3)
