Handling
Culture Medium | McCoys 5a, w: 3.0 g/L Glucose, w: stable Glutamine, w: 2.0 mM Sodium pyruvate, w: 2.2 g/L NaHCO3 (Cytion article number 820200a) |
---|---|
Medium supplements | Supplement the medium with 10% FBS |
Passaging solution | Accutase |
Doubling time | 35 hours |
Subculturing | Remove medium and rinse the adherent cells using PBS without calcium and magnesium (3-5 ml PBS for T25, 5-10ml for T75 cell culture flasks). Add TrypleExpress (1-2ml per T25, 2.5ml per T75 cell culture flask), the cell sheet must be covered completely. Incubate at ambient temperature for 10 minutes. Carefully resuspend the cells, the addition of medium is optional but not necessary, and dispense into new flasks which contain fresh medium. |
Split ratio | A ratio of 1:4 to 1:8 is recommended |
Seeding density | 1 x 10^4 cells/cm^2 will result in a confluent layer in about 3 days |
Fluid renewal | 2 to 3 times per week |
Freezing recovery | The cells must rest for a minimum of 24 hours after thawing at 37 degree Celsius/5% CO2 |
Freeze medium | CM-1 (Cytion catalog number 800100) or CM-ACF (Cytion catalog number 806100) |
Handling of cryopreserved cultures |

Quality control / Genetic profile / HLA
Sterility | Mycoplasma contamination is excluded using both PCR-based assays and luminescence-based mycoplasma detection methods. To ensure there is no bacterial, fungal, or yeast contamination, cell cultures are subjected to daily visual inspections. |
