Human FGF21 knockout HeLa cell line (ab265974)

Recommended control: Human Wild Type HeLa cell line (ab255928)

Please note a wild type cell line is not automatically included with a KO cell line order, if required please add recommended wild type cell line at no additional cost using the code WILDTYPE-TMTK1

Cryopreservation cell medium: Cell Freezing Medium-DMSO Serum free media, supplemented with 10% (v/v) DMSO

Handling procedure: Upon arrival, the vial should be stored in liquid nitrogen vapor phase and not at -80°C. Storage at -80°C will result in loss of viability.
1. Thaw the vial in 37°C water bath approximately 1-2 minutes.
2. Transfer the cell suspension to a 15 mL conical tube with pre-warmed 5 mL complete medium DMEM+10% FBS, spin 125×g for approximately 5 minutes at room temperature.
3. Resuspend the cell pellet with 1 mL pre-warmed complete medium DMEM+10% FBS and dispense into a 25 cm² culture flask containing 10 mL pre-warmed complete complete medium DMEM+10% FBS.
4. Incubate the culture at 37°C incubator with 5% CO₂.
5. A subcultivation ratio of 1:4-1:6 is recommended. Cells should be passaged when cells grow splitting at 80-90% confluence.
