Cell Line: MG-63

Cell Description: Human Osteosarcoma, bone

Culture medium: Minimum essential medium (Eagle) in Earle's BSS with sodium bicarbonate, 2 mM L-glutamine, 1,0 mM sodium pyruvate, 1% non-essential amino acids, 90%; heat-inactivated fetal bovine serum, 10%

Subculture routine: Remove medium, add fresh 0.025% trypsin solution for 2 to 3 minutes, remove trypsin and let the culture sit at room temperature for 10 to 15 minutes. Add fresh medium, aspirate and dispense into new flasks.
